Full textThe two main objectives of this work are to propose tools for the selection of resistant animals to gastrointestinal nematodes and advance knowledge on mechanisms of resistance of creole goats. this work has analysed the genetic variability of resistance to digestive parasitism in order to determine which criteria best describes the resistance and can be use for selection. the overall results suggest that the egg excretion and the eosinophilia are the criteria most suitable for a breeding scheme because they have moderate heritability estimates and best represent the resistance. moreover, they do not seem in conflict with the weight, the main criterion of production. the genetic determinism of resistance to gastrointestinal parasites has been studied and has highlighted the existence of a major gene for resistance in creole goats. in addition, the primodetection of qtl identified 13 genomic regions that affect the resistance. the mechanisms behind the resistance to gastrointestinal parasites were also studied and first hypothesis regarding the involvment of the immune response in resistance have been made in goats. the overall results highlighted the role of eosinophils in the development of resistance to gastrointestinal nematodes. the activity of immunoglobulin e seems directed toward l3 larvae of haemonchus contortus and may be imply in the establishment of a protective response agasint nematode parasites. in creole goats, these two mechanisms seem to play an important role in the development of resistance to gastrointestinal nematode infections

Full textQ fever is a worldwide zoonosis, due to a strict intracellular bacterium: Coxiella burnetii. Domestic ruminants mainly shed the bacteria in parturition products, vaginal mucus and feces. Humans and animals infect by inhalation of circulating pseudo-spores into the environment.Public and veterinary health issues therefore motivated the implementation of this PhD project in order to better control C. burnetii infections on farms. The objectives of this thesis were to provide descriptive epidemiological findings about: (a) circulation dynamics of C. burnetii in a naturally infected flock of sheep; (b) the genotypic diversity of circulating C. burnetii strains on domestic ruminant farms in France; (c) the phenotypic diversity of these strains as demonstrated by the use of two virulence models, one in vivo and one in vitro; and (d) the involvement of horses in the epidemiology of C. burnetii, by studying their exposure and a potential symptomatology.Longitudinal follow-up in a flock of sheep provided relevant tools to rapidly assess the risk of C. burnetii transmission when a flock was identified as infected, in terms of animal pens, diagnostic tools, or sampling periods to be preferred. We also identified three main genotypic groups of circulating strains in domestic ruminant farms in France where Q fever abortion were recorded. Two genotypic groups mainly included small ruminants, with one group mainly composed of sheep and the other mainly composed of goats. The third genotypic group was comprised almost exclusively of cattle. We have shown that the IS1111 gene significantly impacts the genotypic MLVA diversity observed. In addition to this species specificity, we have shown that the circulating genotypes in France were also spatiotemporally stable. We then developed two models of infection, one in vivo by inoculating CD1 male mice in the footpad of and one in vitro by infecting two macrophage cell lines: one bovine (SV40) and one ovine (MoCl4). These two models allowed us to show that the genotypic clusters were not systematically correlated with both the four phenotypic clusters identified in vivo from the analysis of the bacterial load in the mouse spleens and the analysis in vitro of the C. burnetii multiplication kinetics.Finally, the seroprevalence observed in horses within hyperendemic areas for Q fever in humans (Camargue and Plain of La Crau) suggests that horses are exposed to the bacteria in the area and that they may be a relevant indicator of the zoonotic risk. Nevertheless, our results were inconclusive on the clinical forms associated with Q fever in horses.In the future, the findings found in our work will allow a global understanding of the circulation dynamics of C. burnetii on domestic ruminant farms as well as in others animal species. Thus, all these data will ultimately improve surveillance, diagnosis and management of Q fever in public and veterinary health

Full textIn mammals, the embryonic gonad can give either a testis or an ovary. The choice of gonad differentiation depends of the presence or not of a gene bearing by the Y chromosome: SRY. In its presence, the gonad differentiates into a testis and in its absence the ovary differentiation take place. A large number of studies are carried out in order to elucidate the molecular pathway involved in this gonad differentiation. This is also the goal of my thesis using the goat model. Our studies on the PrnD gene seem to show that Doppel protein may be involved in the gonad differentiation. Furthermore, our studies on the R-spondin gene brought new molecular data on the role of both important genes of the ovary differentiation: RSPO1 and FOXL2. For the first time, our results show that an ovary contains two types of somatic cells; those expressing RSPO1 which were in short relation with the germ cells and those expressing FOXL2 which were directly involved in the fetal ovarian steroidogenesis. Our results open different perspectives concerning the RSPO1 role on the germ cells, the link between FOXL2 and one of its putative target gene, RSPO2

Full textThe small ruminant lentiviruses (SRLV) display a high genetic diversity and are currently classified into several groups, and an increasing number of subtypes. While a high prevalence of SRLV infection has been reported in sheep and goats from France, the prevalent SRLV strains circulating in this country are still poorly known. In this study, a large-scale screening method (HMA) based on the sequences of gag and env genes has been developed for monitoring the genetic evolution of SRLV. Molecular epidemiological surveys in sheep and goats flocks from southern of France revealed a high prevalence of subtypes B1 and B2. Interspecies transmission of both subtypes was reported in mixed flocks, as well as co-infection and recombination. However, subtypes B1 and B2 were found with different frequencies in sheep and goats, suggesting a differential adaptation of SRLV subtypes in these hosts. The biological properties of two field SRLV isolates belonging to subtypes B1 and B2 were compared in vitro using different cell types, and in vivo in sheep and goats experimentally infected by intratracheal inoculation. These strains share similar phenotype but exhibit different replicative properties in macrophages and synovial membrane cells. The subtype B1 virus has been shown to be particularly prone to infect goats, compared to sheep. While the subtype B2 virus infects sheep and goats with the same efficiency, viral expression is more frequently detected in sheep than in goats. These results confirm those obtained from field investigations showing specific interaction between SRLV subtypes and their natural hosts

Full textThis study aimed at providing descriptive epidemiological knowledge about the infection of goats by Mycobacterium avium subspecies paratuberculosis, in order to design control schemes. A serological study confirmed that Map infection was widespread in goat herds in France (true prevalence estimated to 63%). Detection of infected animals can be made by ELISA, with a sensitivity of 53% and a specificity of 100%. Best values for ELISA tests were obtained for goats aged 2-3 years. For detection of infectious animals, PCR was the earliest test (from 8 months of age). With PCR as reference test, sensitivities for IFNγ test and ELISA test were estimated to 49 and 29%, respectively. Specificities for the 2 tests were estimated to 100%. Lastly, results are discussed in the perspective of the implementation of infection control schemes and further research topics are proposed

Full textTrans fatty-acids (TFA) are identified as undesirable nutrients in human diets to the documented adverse effects of these fatty acids resulting from partial hydrogenation of vegetable oils (PHVO). However, TFA not only occur in PHVO, but also in the ruminant products, in particular in dairy fats. In this case, the TFA have different isomeric profile with vaccenic acid (VA, trans-11 C18:1) being the major isomer, whereas PHVO mainly contain trans-9 and trans-10 isomers of C18:1. This difference is due in the first case to bacterial hydrogenation in the rumen (R-TFA for ruminant) and in the second case to catalytic hydrogenation (IP-TFA for industrial produced). During the development of this project, no study highlighted association between the R-TFA consumption and increase in the cardiovascular disease (CVD). The first objective of my thesis was to determine the impact of human consumption of dairy fat with fatty acid profile enriched in R-TFA on the biomarkers of cardiovascular risk factor (CVD). Another objective was to study R-TFA metabolism in ruminants. To achieve the 1st objective, three specific ruminant milk fats with increasing TFA content were distributed to human volunteers during 3 weeks nutritional intervention study. Then, in a second stage, was studied the metabolism of VA in the caprine lactating mammary gland by measuring the uptake and conversion of VA to C18:2 cis-9, trans-11 (rumenic acid, RA) using a chemical tracer strategy allowing an in vivo measurement of the delta9-desaturation of VA in goats fed lipid supplements. The clinical intervention study show that a 3 weeks period of consumption of products with 63. 3% of saturated fatty-acids (SFA) and 3. 5% of R-TFA decreases significantly total cholesterol, LDL-cholesterol, LDL-cholesterol/HDL-cholesterol and the CT/HDL-cholesterol compared to commercial dairy fat consumption (72% of SFA and 2. 5% of R-TFA) in human volunteers. Dairy fats with 63. 3% of SFA and 3. 5% of R-TFA appear the optimal balanced in relation to CVD risk. The second study demonstrates in goats fed lipipd supplements that the endogenous synthesis of RA from VA in the mammary gland is the major source of this fatty-acid, since 63 to 73% of RA secreted comes from to the delta-9 desaturation of 32% of VA collected
