Résumé :

An epidemiological survey was undertaken from March to September 2010 to assess the prevalence and zoonotic aspects of scabies in small ruminants in two agro-ecological zones in southern Benin. Small ruminant (n = 444) smallholders and 1,807 of their animals (1,233 West African dwarf goats and 574 West African dwarf sheep) were included in the study. The animals underwent physical examination and, when scabies-like lesions were found, crusts and integument scrapings were collected for microscopic parasitological tests. The samples collected in each survey were coded in accordance with the owner-animal pairings in order to assess the degree of correlation between mange cases in humans (smallholders) and their animals. The overall prevalence of scabies was 28.33% and 9.5% in animals and smallholders (human cases) respectively. Infestations were significantly (p < 0.001) more frequent in goats (39.6%) than in sheep. The uniqueness of the etiological agent (Sarcoptes scabiei), the very high predictive value of human scabies in infected farms (83.67%) and a very high odds ratio (OR = 2,019.25) indicate that small ruminant scabies has been transmitted to smallholders by their animals. Close contact between these smallholders and their animals was a determining factor in this interspecies communicability of sarcoptic mange.

Résumé :

AbstractClose proximity between humans and large predators results in high levels of conflict. We investigated the extent of, and factors leading to, this conflict through focal group and individual interviews in all villages around Pendjari Biosphere Reserve, northern Benin. Livestock losses from 2000 to 2007 (n = 752) were reported to be mainly caused by spotted hyaena Crocuta crocuta (53.6%), baboon Papio anubis (24.8%), and lion Panthera leo (18.0%). These predators mainly predated sheep and goats (52.1%) and pigs (42.3%), with lions being the main predators of cattle (78.9%). Lion and hyaena diets were more diverse than that of baboons, which killed only small stock. The level of conflict increased during 2000–2007. Predation rate differs between predator species and is significantly influenced by month, rainfall of the month before the predation event, and length of the dry period in a year. The geographical position of the village, the distance of the village to the Park and the number of herbivores legally killed every hunting season also influenced predation intensity. Our findings suggest that improvement of husbandry techniques and education will reduce conflicts and contribute to improved conservation of these threatened predators.

Résumé :

The slaughterhouse of Cotonou and the surfaces of slaughtering of Porto-Novo, Abomey-Calavi, Sèmè-Kpodji and Ouidah constitute sources of animal solid matter flow in Large Nokoué. Within the framework of this research, it is refers to the contents of paunches considered for their potential of valorization in the production of biogas and the compost. Then, the quantitative evaluation their layers is a contribution to the efficient use of those as resources or raw materials, for a planning of future management. The methodological approach used is centered on the document retrieval, the datagathering by measurements or weighing of the roughs weight of contents of paunch of the animal species using balance of brand CAMRY as well as recovery of the statistics of slaughtering in the structures in charge of the breeding and the services of inspection of the activities of slaughtering units. The data obtained were treated then the analyzed results. The sample size selected is of 50 individuals of species cattle and 50 individuals of species of caprine sheep. The data analysis was analyzed, inter alia, thanks to software SPSS version 17.0 was used for the statistical analyses. It comes out from this research that each shot down cattle generate 48.5612 kg of waste (contained digestive). It is advisable to recall that the majority of the cattle taken as sample is race zebu and bull-fighting. As for the sheep and goats, each animal generates a quantity of approximately 4.0364 kg of waste. With this average of 48.5612 kg of contents of bovine paunch, and 4.0364 kg for the sheep and goats, the layer of contents the digestive ones was estimated at 1060 tons for the year 2011, and at 1298 tons for the year 2015 at the level of Large Nokoué. If this trend is maintained, this layer could border 2011 tons by 2030. The evaluation of the layers of contents of paunch produces by the activities of demolition the sector of the study regarded as largest parts of the fractions which may undergo beneficiation of the livestock wastes takes part in the installation of strategies of perpetuation of the actions of treatment and valorization within the framework of a sector.

Résumé :

Parapoxvirus infection in sheep and goats is usually referred to ascontagious pustular dermatitis/ecthyma, ororf, and the corresponding human infection is referred to asorf. In humans, after a brief incubation period of 3 to 5 days, lesions begin as pruritic erythematous macules and then rise to form papules, often with a target appearance. Lesions become nodular or vesicular, and orf lesions often ulcerate after 14 to 21 days. Erythema multiforme and bullous pemphigoid have been associated with parapoxvirus infections and they are rare complications of orf disease. In this case report, we presented a 36-year-old woman with history of contact with sheep, developing a typical orf lesion that is complicated with erythema multiforme and bullous pemphigoid-like eruptions.

Résumé :

Footrot in sheep is a chronic, infectious disease of the acropodium in sheep, less frequently in goats and mountain goats, of a multifactor nature, which is also considered to be a disease of poor management in sheep breeding. Over the recent years, Dichelobacter nodosus is given as the main cause, previously known as Bacteroides nodosus. Coaction with several other saprophytic and pathogenic bacteria is no longer so significant in etiopathogenesis, and it is considered more important to determine the virulence of the strain D. nodosus. The disease is called contagiousus ovine digital dermatitis (CODD) if the infection was caused by a very virulent strain of D. nodosus, and the disease often ends with the so-called removal of the foot. A speedy identification of the agent can provide insight into the clinical form of the disease, its course and predicted outcome. A benign strain of the agent causes only a mild to medium virulent laminitis, with poorly expressed interdigital dermatitis, when the animal openly limps on one or two legs. A very virulent strain leads to a grave form of infectious interdigital dermatitis, as a supurous-necrotic dermatitis, with significant damage to the bone and expressed limping of the animal. Footrot is present in sheep in almost all countries of the world, in particular in countries with a developed sheep production (New Zealand, Australia and the United Kingdom), where it causes significant economic damages. In our country, footrot in sheep occurs mainly in the Raska district, eastern Serbia and Vojvodina province, but the percentage varies from herd to herd. The irregular and incorrect processing of hoofs (an important zootechnical measure) significantly contributes to the occurrence and spreading of this disease, as well as a series of other contributing factors, such as soft and moist earch, bad climatic conditions (warm and humid weather). In activities on prevention and prophylaxis of this disease, as well as the treatment of footrot in sheep, which is complex in nature, there have been attempts to apply different disinfectants. For instance, disinfection with 10% copper sulphate, 5-8% formalin, as well as, more recently, zink sulphate, either in the form of a powder or as a solution (from 10-20% ZnSO4), several times during different time intervals, are recommended in literature and are being implemented in practice. There are a number of prescriptions for disinfection of hoofs and some of them have been shown to be very efficient. Zinc sulphate has certain advantages in hoof disinfection: it is a bactericide, it penetrates deeper into the tissue in the crucial spot, it protects the horny part of the hoof, it is less toxic, ecologically acceptable (more readily disposable), and less expensive than other mentioned disinfectants. The use of antibiotics is justified only in individual isolated cases, in the treatment of interdigital dermatitis diagnosed on several legs. However, the application of wide-specter antibiotics sprayed into the interdigital space has proven justified and efficient. Immunoprophylaxis yields different results and is mostly implemented in lambs and sheep in early stages of gravidity. Only regular and expert processing of hoofs, using a zinc sulphate disinfectant in the form of a solution according to a prescribed procedure, the use of antibiotics in rare cases, putting animals to pasture in well-drained soil, and vaccination of certain categories of animals can all significantly contribute to the efficient eradication of this persistent disease in sheep.

Résumé :

The theoretical analysis of possible single-factor regressions, which correspond to the decrease in the number of livestock of agricultural animals during the crisis period and increase their number at the exit from the crisis state, is made in the work. It is shown that during the crisis period, the dynamics of the reduction of the livestock correspond to the modified exponential regression. It is proposed to find two parameters of these regressions using the least squares method, the third one to be determined by the numerical method with a minimum of MAPE. With the growth of livestock caused by an increase in investments, this evolution corresponds to a modified logistic regression. The two logistic regression parameters find using the least squares method, the third and fourth parameters were determined by numerical method with a minimum of MAPE, as functions of two variables. The obtained theoretical conclusions are in good agreement with the statistical data that correspond to the dynamics of the number of cows, pigs, sheep, goats and poultry in Ukraine for the period 1995-2017. It was shown that changes in the number of cows during the whole period under investigation correspond to the modified exponential regression. The stock of pigs from 1995 to 2001 in agricultural enterprises of Ukraine also decreased under the exponential law. Since 2002 there has been a gradual increase in the number of pigs - including until 2013. In this period, the dynamics corresponded to the logistic regression of Pearl-Reed. Beginning in 2014, due to the loss of part of Ukraine's controlled areas and the complicated epizootic situation (African swine fever), the gradual decrease in the number of pigs began. The modified exponential regression also corresponded to the change in livestock of sheep and goats in agricultural enterprises of Ukraine in 1995-2005. From 2006 to 2010 there was a slight increase in livestock, then its gradual decrease, and from 2014 the total number of sheep and goats was again in line with the modified exponential regression. The dynamics of the number of poultry in agricultural enterprises in Ukraine resembles the process of changing the number of pigs. At first, it decreased, then grew. Between 1995 and 2000, the number of poultry decreased by exponential dependence. Starting from 2001 to 2013, the number of poultry increased annually, which is explained by the significant increase in the volume of state support for the poultry industry. During this period, the change in the size of the poultry fitted well with the modified logistic regression of Pearl-Reed. In 2014-2016, the number of poultry decreased annually, primarily due to changes in the geographical structure of exports. In order to begin the outbreak of the livestock sector from the crisis, it is necessary to increase the volume of domestic and foreign investment in fixed capital, increase the purchasing power of the population, the level of purchasing prices for milk and meat, improve the credit policy, and increase the amount of state aid to agricultural producers. In addition, it is necessary to create appropriate conditions for the expansion of product markets, first of all, by ensuring the process of modernization of production on an innovative basis, which will contribute to improving the quality characteristics of manufactured products in accordance with modern requirements of European and international standards. The said will allow to significantly increase the volume of agricultural production and will contribute to increasing the competitiveness of national agrarian commodity producers both in the domestic and world markets. Key words: animal husbandry in agricultural enterprises, logistic and exponential regression, forecasting.

Résumé :

Gastrointestinal nematodes limit the growth, production and welfare of goats but there are few reliable sources of information for recommending management practices across flocks. The effects of animal species (Angora goat, Merino sheep, mixed-grazed goats and mixed-grazed sheep at the ratio of 1 : 1) and stocking rate (SR: 7.5, 10, 12.5 animals/ha) on gastrointestinal parasitism were determined in a replicated experiment on improved annual temperate pastures in southern Australia, from 1981 to 1984. Detailed monitoring of gastrointestinal nematodes was undertaken on animals before, during (five times per year) and at the conclusion of studies using faecal strongyle egg counts (WEC) and total worm counts. Sheep had a greater proportion of nematodes as Teladorsagia spp. and goats a greater incidence of Trichostrongylus spp. Both goats and sheep developed resistance to Nematodirus spp. during the experiment. WEC was similar in goats and sheep at the start of the experimental period but, thereafter, was consistently greater in goats than in sheep. While WEC was highly related to total worm count, the regressions for sheep and goats were different. Increasing the SR increased the WEC of goats and mixed-grazed goats but not of sheep. During the experiment, WEC declined at 7 and 10 animals/ha but increased at 12.5/ha. Mixed grazing with goats provided beneficial effects for sheep at all stocking rates, but the effects for goats were dependent on the stocking rate, being beneficial at 7.5 and 10/ha but harmful at 12.5/ha. The WEC of separately grazed goats were generally higher than the WEC of mixed grazed goats. The WEC of mixed sheep were lower than those of separately grazed sheep. During the experiment, the WEC of mixed grazed sheep declined faster than the WEC of separately grazed sheep but the WEC of separately grazed goats at 12.5/ha and of mixed grazed goats at 10 and 12.5/ha increased. Under the environmental and pastoral conditions examined, Angora wether goats should not be grazed at SR above those recommended for wether sheep. In the present study, the impact of gastrointestinal-nematode infections in goats was reduced at lower SR. Further, mixed grazing of Angora wether goats with wether sheep at or below the recommended SR resulted in reduced gastrointestinal parasitism for both sheep and goats, compared with monospecific grazing conditions. Goats did not represent a gastrointestinal-nematode hazard to sheep.

Résumé :

The objective of the present work was to elucidate some of the possible choice determinants involved in diet selection by sheep and goats. The first experiment investigated the ingestive and digestive responses of these two species to a range of forage chemical composition attributes (i.e. nitrogen and fibre content). Forage DM intake was positively associated with their nutritive quality. Goats had higher voluntary DM intakes (P<0.05) and lower apparent digestibility coefficients (P<0.001) for any given forage than sheep, but the intake of digestible DM was similar for the two species. When forages were offered in pairs in a preference trial, the two species ranked forages similarly by favouring those of higher nutritive quality. The second experiment investigated the effects of different staple lengths of a single hay on the ingestive and digestive responses of sheep and goats. Goats had higher voluntary DM intakes (P<0.05) and lower apparent digestibility coefficients (P<0.001) for any given length than sheep, but the intake of digestible DM was similar for the two species. Goats allocated less time (P<0.001) than sheep to chewing the feed consumed and the mean retention time of the undigested residues in the animals' digestive tract was significantly shorter (P<0.01) for goats than sheep. When staple lengths of the grass hay were offered in pairs none of them was favoured and the choices were not significantly different between goats and sheep. In a third experiment a new method of feed presentation was developed and compared with conventional feed-bins. Goats had higher voluntary intakes than sheep (P<0.05), whereas there was no effect of the feed presentation method on DM intake.

Résumé :

Measurements of energy expenditures for domestic animals are used as a basis to determine the total energy requirements for maintenance and for production. Most studies on energy metabolism have been conducted under controlled, confinement conditions, and the results extrapolated to free - ranging animals. Such approaches do not always represent the real energy costs of free existence in the range or pasture environment. This study compared energy expenditures of sheep and goats under free-grazing conditions and assessed the accuracy of the carbon dioxide entry rate technique (CERT) as compared to the oxygen consumption method. In addition, 24-hour activity budgets were used to construct energy budgets for both animal species. These estimates were compared to CERT measurements. Dietary organic matter, crude protein, gross energy, digestible protein, and digestible energy intakes, as well as the apparent digestibility coefficients for crude protein and gross energy were compared for both species in one of the grazing trials. The validation of CERT yielded the linear regression equation: Y = 0.878 + 5.333 ER where Y energy expenditure in Kcal·min-1, and ER is the C02 entry rate in grams of C02 carbon·min-1. The coefficient of determination (r2) was 0.979, and the residual standard deviation of ± 0.12 Kcal·min-1. Daily energy expenditure of goats was higher (P<.OS) than that of sheep in all grazing experiments. The overall means were 127.1 and 88.4 Kcal·Bw-.75.d-1 for goats and sheep, respectively. High ambient temperatures during one of the grazing trials apparently caused heat stress to the grazing animals. Both species responded to this situation by using behavioral adaptations and avoidance mechanisms. The energy budget method over-estimated energy expenditures of sheep by 9 percent, and grossly underestimated the energy expenditures of goats by 39 percent. The nutritive value of the diets selected by both species was similar . However, goats had higher (P< .OS) organic matter, crude protein, gross energy, digestible protein and digestible energy intakes. The apparent crude protein digestibility coefficient for goats was 20 percent higher (P<.OS) than that for sheep. On the other hand, gross energy digestibility coefficients were similar for both species. Goats appeared to have an edge in meeting their dietary protein requirements under free- ranging conditions. CERT can predict energy expenditures within ± 8 percent of the mean. It is a feasible technique for assessing energy expenditures of small ruminants under range conditions. The energy budget method was not reliable for estimating energy costs in small ruminants, especially goats.

Résumé :

Mycobacterium avium subspecies paratuberculosis (Map) infects macrophages and causes severe lesions of chronic granulomatous enteritis in sheep and other ruminants (Johne's disease). In this study, ovine paratuberculosis cases were examined histologically, and the presence of two distinct forms of intestinal pathology confirmed, characterised by either multibacillary lesions which exhibited a positive correlation with the presence of a marked macrophage infiltrate (lepromatous cases), or paucibacillary lesions which showed correlation with a cellular infiltrate which was lymphocytic in nature (tuberculoid cases). The presence of acid-fast bacteria was also found to correlate with evidence of serum antibody. Genomic DNA was extracted from the ileum of infected sheep and polymerase chain reaction (PCR) performed using IS900 primers to confirm Map infection. Immunoperoxidase staining of ileum demonstrated that the lymphocyte populations differed in density and relative percentages between both histological groups. The tuberculoid group had higher densities of CD4+, CD8+ and γδTCR+ subsets, and the lepromatous group lower densities of CD4+ and CD8+ subsets, when compared with control animals. Tuberculoid cases were associated with an increase in the relative percentage of CD4+ lymphocytes, whereas lepromatous cases had an increased relative percentage of γδTCR+ cells. Flow cytometry of lamina propria lymphocytes (LPL) isolated from the ileum of infected and control animals confirmed increased percentages of γδTCR+ cells in lepromatous cases than in controls, and higher percentages of CD8+ and γδTCR+ cells than in tuberculoid cases, which had correspondingly higher percentages of CD4+ cells. Higher percentages of γδTCR+ cells were also noted in mesenteric lymph node lymphocytes (MLNL) from lepromatous cases compared with control animals. Peripheral blood lymphocytes (PBL) of infected animals had increased percentages of B cells, and an associated increase in the percentage of MHC Class II positive cells compared with normal controls. The findings of this study suggest that ovine paratuberculosis is a disease with an immunological spectrum broadly comparable with that described for leprosy, with an apparent Thl like response in the tuberculoid form and a Th2 like response in the lepromatous form.

Résumé :

Two experiments were conducted on sown grass/clover swards (Lolium perenne - Trifolium repens) to study the effect of domestic animal species (sheep, goats and cattle) on sward canopy structure and diet selection and animal performance of a subsequent grazing species. In Experiment 1, the effects of continuous grazing by sheep, goats or cattle at a sward surface height of 6 cm from mid-May to late July (Phase 1) were assessed. From late July until the end of August (Phase 2) swards were continuously grazed at 6 cm by sheep or goats. Sward composition and structure were measured by a stratified clipping technique taking account of short, medium and tall areas on the basis of their mean sward surface heights and separated into grass and clover morphological components. In Phase 2 the diet selected by oesophageally fistulated goats and sheep was measured. Swards previously grazed by cattle tended to have a higher percentage of clover than those previously grazed by sheep and by goats both in the whole sward and on the sward surface at the end of Phase 1 (sward: 11.8% versus 9.5% and 8.8% respectively; sward surface: 18.2% versus 11.1% and 7.60% respectively). This was particularly related to higher amounts of clover in short and tall areas. During Phase 2 sheep ingested a significantly higher percentage clover from cattle-grazed swards (cattle: 29.7%, sheep: 13.3% and goats: 12.6%; p<0.001) whereas the diet of the goats contained 17.3%, 14.0% and 18.9% from cattle, sheep and goats-grazed swards respectively. Furthermore, during Phase 2, there was a greater overall increase in the clover percentage on swards grazed by goats than in those grazed by sheep. Both sheep and goats ingested more clover from tall areas of the sward with 32.2% and 20.1% of the variation in the percentage of clover in their diets respectively attributed to the percentage of clover present in these areas.

Résumé :

A cell synchronization technique was used that consistently yielded numerous elongated chromosomes, which are necessary for producing high-resolution G-banding. The prometaphase stage of contraction was determined to have the greatest utility for detailed comparative analysis and, therefore, was used in the preparation of the proposed standard high-re solution karyotypes and idiogram. A proposed standard high-resolution G-band karyotype of the domestic sheep and goat is presented, along with a high-resolution G-band idiogram of the goat. The karyotypes presented contain considerably more bands than contemporary karyotypes and provide much greater resolution for linear differentiation. The X chromosome of the sheep is acrocentric, rather than having a minute p arm as recently reported. A side -by-side comparison of high-resolution G-band sheep and goat chromosomes indicates identical equivalence of banding patterns. Of special note is the homology of banding patterns for the six acrocentric autosomes of the goat and the respective three submetacentric autosomes of the sheep, reinforcing the evidence that the goat is representative of the ancestral karyotype. C-bands and NORs of the sheep and goat are also presented. When C-banded, the centromeric regions of the sheep and goat acrocentric autosomes were found to be densely stained. The centromeric regions of the X and Y, however, were not stained differently from the chromosome arms. In the sheep submetacentrics, chromosomes 1 and 3 showed weak C-bands while chromosome 2 showed stronger bands. In the sheep and goat, 10 NORs located terminally on five chromosomes pairs were found. Sheep NORs occurred on the three pairs of submetacentric autosomes and on one large and one small pair of acrocentric autosomes. Goat NORs occurred on four large and one small pair of acrocentric autosomes. Sine the banding patterns obtained when staining for NORs do not permit individual identification of each chromosome, duplicate G-banding and silver staining of elongated chromosomes of both sheep and goat would need to be conducted to identify specific NOR-bearing chromosomes.

Résumé :

Small-ruminant production is an important part of the agricultural economy of northeastern Brazil. However, mild-to-severe undernutrition of livestock is an annual occurrence. Goats can tolerate the marginal forage conditions better than sheep, but the mechanisms underlying their superior tolerance are not understood. An analysis of animal liveweights at the end of the year-long study indicated that reproducing mixed-race goats gained nearly twice (P<.05) the weight of reproducing hair-sheep of the Santa Ynez breed, and non-reproducing goats gained about 1.2 times more (P<.05) weight than non-reproducing sheep. Daily weight gains of lambs were less (P<.10) than those of Kids for their first 80 days of life. In the wet season, reproducing sheep and goats gained similar (P>.05) weight, while non-reproducing sheep gained more (P~.05) than non-reproducing goats. Non-reproducing goats had greater (P<.05) forage organic matter intake (OMI) than the corresponding sheep in the two wet periods. In the late-wet period, non-reproducing goats had greater (P<.05) digestible energy intake (DEI) than corresponding sheep did but had similar (P>.05) digestible protein intake (DPI) as sheep. In the dry season, reproducing sheep and goats lost similarbn(P> . 05) weight but only the five better performing sheep were weighed at the end of the dry season. The five poorer performers were removed from the study and given supplemental feed to keep them alive. The non-reproducing sheep lost weight during the dry season, while the non-reproducing goats gained weight . Non-reproducing sheep and goats had similar (P>.05) OMI and DEI during the dry periods. In the late-dry period when forage quality was lowest, the animals experienced their greatest weight loss, and both species had greatly reduced DPI; the goats had 83 percent greater (P<.05) DPI than the sheep. Digestion trials were conducted with actual diet samples selected by free-ranging animals. Goats had greater (P<.05) crude protein apparent digestibility than sheep in the late-dry period trial. This difference may be a key aspect explaining their responses to the dry season.

Résumé :

Brucellosis is a constraint to livestock production in Moçambique. Reproductive failure due to brucellosis has been reported in the country and abortions occur in cattle, sheep and goats on many of the farms in Maputo Province of Moçambique. Brucellosis is an infectious disease affecting mainly sexually mature animals and is caused by organisms of the genus Brucella. Brucella abortus is the species that mainly affects cattle throughout the world, while Brucella melitensis affects mainly goats and sheep. Control of bovine brucellosis using B. abortus S19 vaccine was undertaken before the civil war in Moçambique which started in 1978 and ended in 1992. During this period the vaccination status of animals was not known. The diagnosis of brucellosis is mainly based on serological surveys and conflicting results obtained previously emphasized the need for additional studies. The aims of this research were to determine the prevalence of brucellosis in cattle, goats and sheep due to B. abortus and B. melitensis in five districts of Maputo Province based on serology, and to assess the relationship between abortions and reproductive failure occurring in the study area by isolation of Brucella organisms or nucleic acid detection. A total of 971 adult beef and dairy cattle, 752 goats and 260 sheep from the study area were tested for Brucella antibodies using the Rose Bengal test (RBT), indirect ELISA and complement fixation test (CFT). Milk from 85 dairy cows and tissue samples from 32 cows and bulls from Gaza and Inhambane provinces slaughtered in Maputo municipal abattoir and Machava abattoir, and an aborted foetus were also examined. All serological test results for small stock were negative. An overall apparent prevalence of 14.0% (n=971) was found in beef and dairy cattle in the study area based on a 95% confidence interval. The highest prevalence was observed in Manhiça District (27.4% (n=180)) with a significant difference compared to other districts (p<0.05). The lowest prevalence was observed in Magude District (7.1% (n=241)). The prevalence in the remaining districts were 14.5% (n=138) in Matutuine, 8.7% (n=173) in Moamba and 14.6% (n=239) in Boane. Apparent prevalences of 15.5% (n=161) in small, 14.0% (n=578) in medium and 12.9% (n=232) in large livestock production sectors where found in the study area with no significant differences (p>0.05) between them. B. abortus was isolated from the spleen of an aborted foetus. A PCR amplification product of 600bp was generated from this isolate 584/05 and from the organs of five slaughtered cows using primers ISP1 and ISP2 for Brucella genus-specific sequences. The isolate 584/05 was confirmed as a B. abortus field strain when fragments of 498bp and 178bp were generated using a PCR assay for differentiation of B. abortus field strains and vaccine strains 19 and RB51. A correlation was made between the 584/05 isolate and serum from the cow that aborted. The results confirmed that the isolate was not a vaccine strain. The results from this study will supplement existing epidemiological data and aid brucellosis control programmes in Moçambique. Copyright
