Abstract:
Coccidiosis is a protozoan disease of the Eimeriidae family, mostly caused by Eimeria species, sometimes Isospora species, seen in all domestic and wild animals, especially in young animals, which can result in hemorrhagic diarrhea, depression, weakening, weight loss, and sometimes death. Eimeria bovis, E. zuernii, E. auburnensis, E. ellipsoidalis, and E. alabamensis cause clinical coccidiosis by showing pathogenic properties. The disease is more important for young people. In its diagnosis, the age of the animal, the hygienic condition of the environment and clinical signs are evaluated. Clinical findings and stool consistency in calves and calves are also important in diagnosis. In the treatment of coccidiosis is based on the principles of killing the causative agent or preventing its development, eliminating fluid loss, and treating secondary infections. The treatment of coccidiosis in calves naturally infected with E. zuernii and E. bovis, oral administration of 15mg/kg dose of toltrazuril is reported to be very effective and reduces economic losses by positively affecting the growth performance of animals. In studies conducted in our country, 11 Eimeria and 1 Isospora species have been found in cattle. In studies on bovine coccidiosis in Turkey, the prevalence of Eimeria species in calves and calves was found to be 16-93.3%. In line with the results obtained, it has been observed that coccidiosis continues to be a problem even in cattle farms with relatively good care and feeding conditions in Turkey. It was concluded that routine checks should be made in the enterprises, necessary precautions should be taken and hygiene rules should be followed.

Abstract:
The goal of the present research was to figure out the prevalence and risk factors of coccidiosis in goats and sheep in Dera Ghazi Khan. For this 752 (goats=376; sheep=376) fecal specimens were obtained, and were analyzed by coprological examination. The prevalence of coccidiosis in sheep (52.92 %) was significantly higher (P<0.05) than the goats (44.41 %). In females, infection with Eimeria was significantly higher (P<0.05) as compared to male animals. Coccidiosis was significantly more common (P<0.05) in sheep and goats aged ≤6 months compared to sheep and goats older than 6 months but less than a year, and older than a year. There was a clear distinction (P<0.05) in prevalence of coccidiosis in animals that are stall fed and housed in comparison with the animals that graze in open grasslands. Prevalence of coccidiosis in animals with low BCS was considerably higher (P<0.05) as compared to the animals in good health. The prevalence of Eimeria infection and fecal score had a significant correlation (P<0.05). Prevalence of coccidiosis was higher in August while in October it was lowest. The highest prevalence (56.78%) was of E. ovinoidal is followed in order by 47.23 % E. ahsata, 35.67 % E. parva, 30.15 % E. intricate, 26.63 % E. faurei and 19.09 % E. pallid in sheep. In case of goats, highest prevalence (68.86%) was of E. ninakohlyakimovae, followed by 59.88% E. alijevi, 53.29% E. arloingi, 46.70 % E. caprinaand 22.15 % E. hirci were among the most common Eimeria spp. It was concluded that different Eimeria spp. Prevailing in study area with variable risk factors and the incidence of coccidiosis in research area was affected by various risk variables.

Abstract:
Avian coccidiosis is a huge problem worldwide. Heavily infected animals that show severe clinical signs and coccidiostat resistance are causing important economic losses. The present study aimed to update the recent cases of coccidiosis in Central Java, Indonesia, and to show the importance of the disease in the region. A total of 699 samples were obtained from different chicken breed. Different Eimeria species were detected in 175 individuals (25.04%). Three different groups of chicken breed were considered: local chicken (autochthonous chickens of Sentul and Jawa), commercial broiler, and layer. Broiler chickens showed the highest prevalence of infection (34%), followed by layer (26.26%) and local chickens (10.45%). Mild to severe clinical signs of avian coccidiosis were observed in 42% of the infected animals, while 58% of the infected animals showed no clinical signs other than low feed conversion rates. Seven different Eimeria species were identified: E. tenella was the most prevalent (43.3%), followed by E. maxima (26.3%), E. necatrix (15.7%), E. acervulina (8%), E. praecox (3.1%), E. mitis (2.2%), and E. brunetti (1.3%). Coinfections with several Eimeria species were diagnosed. With this study we found massive usage of coccidiostat in the region even though its usage cannot guarantee coccidiosis-free chicken production.

Abstract:
Background and aim: Coccidiosis is a host-specific protozoan disease caused by several species of Eimeria genus, resulting in variable economic drawbacks due to loss in performance and even mortality. The current study investigated the prevalence rate of coccidiosis in goats and sheep in Wasit province (Iraq), morphological detection of the main Eimeria species found in these animals, and identification of the relation between positive infections and specific epidemiological risk factors. Materials and methods: Fresh fecal samples of 300 animals involving 150 goats and 150 sheep of various ages and sexes were collected during January-December (2022), prepared, and examined microscopically. Results: The overall prevalence rate of coccidiosis among study animals was 32.33%, including 38.67% in goats and 26% in sheep. Based on their morphology, 7 and 4 Eimeria species were identified in goats and sheep, respectively, with a significant prevalence of E. arloingi in goats and E. ahsata in sheep. Mixed infection patterns appeared significantly in goats and sheep compered to single and bilateral patterns. An insignificant association between body temperature, pulse, and respiratory rates of infected and non-infected animals was observed, while values of body condition score were recorded as poor scores in goats and medium scores in sheep. Age, sex, region, and season showed a significant association with coccidiosis. Conclusion: Coccidiosis remains highly prevalent, subclinical parasitic disease in small ruminants in particular goats. Therefore, successful and economical control can be achieved once detailed knowledge about management characteristics and the time course of infection in a given flock is collected. Also, implementing of advanced diagnostic assays such as molecular phylogeny could help increase the sensitivity and specificity of an assay in identifying different Eimeria species and their association with other local and global strains

Abstract:
Coccidiosis have been reported to cause severe economic losses in small ruminants livestock industry. Subclinical coccidiosis is common among small ruminants and clinical occurs mainly in young's animals. Coccidiosis is caused by highly host-specific Eimeria species. Strategies to control traditionally rely on the use of management practices combined with anticoccidial treatments. The development of alternative, safer, and ecofriendly anticoccidial agents have become priority in most parts of the world. Essential oils have been shown to exhibit antiparasitic activity and may control protozoal pathogens. The purpose of this review is to provide an overview of Eimeria species in sheep and goats and demonstrated life cycle, clinical signs, diagnosis, treatment and potency use of essential oils in the treatment of coccidiosis.

Abstract:
Coccidiostats are a group of veterinary antibiotics, the residues of which in, e.g. meat or other edible tissues, are potentially dangerous to human health and life. Thus, it is important to effectively prevent intoxications. For that purpose it is essential to gather data on those antibiotics. Coccidiostats are used mainly in treating and preventing coccidiosis – a disease of the intestinal track of animals, especially of the poultry, caused by parasitic protozoans of the Eimeria genus. Two major groups are used – polyether ionophores and chemical coccidiostats, which differ in origin and mechanisms of action. Their application is governed by the Regulation (EC) No 1831/2003 of the European Parliament and of the Council, in which the application of the following 11 coccidiostats was authorized: salinomycin, narasin, monensin, maduramicin, semduramicin, lasalocid, robenidine, nicarbazin, halofuginone, diclazuril and decoquinate. Each of the mentioned coccidiostat present in the products of animal origin can lead to intoxication resulting from production errors and poor manufacturing practices. The effects of those compounds in food include symptoms such as: polyneuropathy, rhabdomyolysis, hypercalcaemia, respiratory failure and even death of patients. The coccidiostats are irreplaceable in treating coccidiosis, which can always be associated with the possibility of their occurrence in food. The present-day methods used to identify these medicines make it possible to monitor the products as regards the occurrence thereof and to reduce the risk of exceeding safe dose limits as set out in the relevant legal acts.

Abstract:
"Infection with coccidia is one of the most common and damaging sheep diseases, particularly young lambs and economically important diseases of sheep. Coccidiosis is caused by parasitic protozoa in the genus Eimeria. Coccidial infection is virtually universal in sheep and large numbers of oocysts may be found in the faeces of clinically normal animals. Usually it is presented at animals at 4-10 weeks.Lamb and kids infection had moderate morbidity and low mortality rate. Environmental contamination and resulting clinical disease is generally influenced by local weather conditions and the grazing management practices of the flock. In our paper, we present measures to control coccidiosis in sheep kept in frame breeding conditions."

Two studies were carried out to evaluate, trough meta-analysis, the relationship between parasitosis and animal performance of broiler and growing pigs. Databases totaled 43,976 broilers (69 articles published between 1982 and 2010) and 1,279 growing pigs (18 articles published between 1971 and 2010). Meta-analyses followed three sequential analyses: graphic, correlation and variance-covariance. Pigs challenged by endoparasites presented reduction (P<0.001) of 5% on feed intake and 31% on weight gain. Broilers challenged by E. acervulina and E. tenella presented feed intake similar (P>0.05) to control group. However, the groups challenged by E. maxima and Pool presented increase on feed intake by 27% and 5% compared to control group. In relation to broilers weight gain, all challenged groups presented reduction (P<0.05) compared to control group. The average reduction was 10%, with the exception of the group challenged by E. maxima which showed a 23% reduction in daily weight gain compared to control group. The average age and average body weight of challenged animals, and the crude protein intake were the variables that most adjusted the determination coefficient in the equations for estimating the weight gain of parasitized pigs. Considering parasitized broilers, the reduction in feed intake was the variable that best explains the reduction in weight gain. Variance decomposition showed that parasitosis were responsible by a 6% reduction in weight gain for pigs and coccidiosis were associated by less than 1% for broilers. In addition, this analysis showed that most of the variation in weight gain was explained by the variation in feed intake (59% in pigs and 91% in broilers, on average). Parasitosis influences the performance of broilers and pigs. However, the magnitude of these effects varies with the parasite species, sex, age and line of the animal as well as nutritional factors.
Dois trabalhos foram desenvolvidos com o objetivo de estudar, através de meta-análise, a relação das parasitoses com o desempenho de frangos de corte e suínos. As bases de dados totalizaram 43.976 frangos de corte (69 artigos, publicados entre 1982 e 2010) e 1.279 suínos (18 artigos, publicados entre 1971 e 2010). A meta-análise foi realizada através de três análises sequenciais: estudos gráficos, de correlação e de variância-covariância. Suínos desafiados por endoparasitas apresentaram (P<0,001) redução de 5% no consumo de ração e de 31% no ganho de peso. Frangos de corte desafiados por E. acervulina e E. tenella apresentaram consumo de ração semelhante (P>0,05) em relação ao grupo controle. Já os grupos desafiados por E. maxima e Pool apresentaram aumento (P<0,05) no consumo de ração de 27% e 5% em relação ao grupo controle. Em relação ao ganho de peso dos frangos, todos os grupos desafiados apresentaram redução (P<0,05) quando comparados com o controle, A redução foi em média de 10%, com exceção do grupo desafiado por E. maxima que apresentou 23% de redução no ganho diário de peso em relação ao grupo controle. A idade média e o peso médio dos animais desafiados, bem como o consumo de proteína bruta, foram as variáveis que mais ajustaram o coeficiente de determinação nas equações para estimar o ganho de peso dos suínos parasitados. Para os frangos de corte parasitados, a redução no consumo de ração foi a variável que melhor explicou a redução no ganho de peso. Por decomposição da variância, foi verificado que as endoparasitoses foram responsáveis por 6% da redução no ganho de peso para os suínos, e as coccidioses foram responsáveis por menos de 1% para as aves. Além disso, a decomposição da variância mostrou que a maior parte da variação no ganho de peso foi explicada pela variação no consumo de ração (59% nos suínos e, em média, 91% nas aves). As parasitoses influenciam o desempenho dos frangos de corte e suínos. No entanto, a magnitude destes efeitos varia com o a espécie de parasita; o sexo, a idade e a linhagem do animal; bem como com fatores nutricionais.

Abstract:
Eimeria maxima é uma das principais espécies que causam a coccidiose aviária. Visando uma maior compreensão dos mecanismos moleculares envolvidos na esporulação de oocistos de E. maxima, o perfil da expressão gênica em oocistos não esporulados, parcialmente esporulados e esporulados foi avaliado utilizando a técnica ORESTES. As 20.149 leituras geradas foram pré-processadas, agrupadas, anotadas empregando-se a plataforma Egene e em seguida, analisadas estatisticamente. Um total de 1.207 contigs e 2091 singlets foi gerado. Cerca de 72% dos transcritos foram classificados como proteínas hipotéticas, 20% eram similares a proteínas de função conhecida e 8% eram proteínas conservadas. Após a análise estatística, 32% dos transcritos foram classificados como diferencialmente expressos, dos quais, a maioria (65%) era estágio-específica. Para validação dos perfis de expressão obtidos por ORESTES, a expressão diferencial de um pequeno conjunto de genes foi quantificada por RT-qPCR. Os resultados demonstraram boa correlação entre as duas técnicas.
Eimeria maxima is one of the most important causing agents of poultry coccidiosis. Aiming at obtaining a better understanding of the molecular mechanisms involved in oocyst sporulation of E. maxima, the gene expression profiles of unsporulated, sporulating (sporoblast phase) and sporulated oocyst were studied using the ORESTES methodology. The 20,149 reads generated were pre-processed, grouped, annotated employing the platform Egene and statistically analyzed. A total of 1207 contigs and 2091 singlets were generated. About 72% of the transcripts were classified as hypothetical proteins, 20% were similar to proteins of known function and 8% were conserved proteins. After statistical analysis, 32% of the transcripts were classified as differentially expressed of which 65% were stage-specific. For ORESTES validation, the differential expression was quantified by RT-qPCR to a small set of genes. The results demonstrated a good correlation between the two techniques studied.

The objective of this study was to evaluate the supplementation of L-glutamine in the diet of chickens on the floor and fed diets without anticoccidial agents and promoters of growth. Were used 500 chicks, males, Cobb distributed in randomized blocks design with five treatments and four replicates with 25 birds each. The treatments consisted of increasing levels of glutamine in the diets (0.0, 0.5, 1.0, 1.5 or 2.0%) throughout the rearing period, 42 days old. Were evaluated performance, digestibility (18-21 days), carcass yield and Histomorphometry of small intestine (18 and 42 days old). Data were submitted to polynomial regression analysis and means compared by Scott Knott (0,05) test. There was an effect of glutamine supplementation only during pre-starter feed, and the best level of feed addition of 1%. The results for performance up to 42 days of age, carcass yield and nutrient digestibility of the diet showed no difference (P> 0.05) between the levels of glutamine in the diet. histomorphometry at 18 days of age difference was observed for crypt depth in the small intestine (duodenum, jejunum and ileum) (P <0.05), being the duodenum and ileum the best level of glutamine was 2% and jejunum 1%. For the results of histomorphometry at 42 days old, significant effect of glutamine to crypt depth in duodenum, jejunum and ileum, with the highest levels found in 1, 0.5 and 2% respectively. It is recommended the addition of 1% L-glutamine in the pre-started the improvement of feed conversion rate at 1-7 days of age and better development of the small intestine.
Objetivou-se com este estudo avaliar a suplementação da L-glutamina na ração de frangos criados no chão e alimentados com rações sem agentes anticoccidianos e promotores de crescimento sobre desempenho, rendimento de carcaça, digestibilidade e desenvolvimento intestinal. Foram utilizados 500 pintos, machos, da linhagem Cobb distruibuídos em delineamento em blocos ao acaso com cinco tratamentos e quatro repetições com 25 aves cada. Os tratamentos estudados foram níveis crescentes de glutamina nas rações (0,0; 0,5; 1,0; 1,5 ou 2,0%) durante todo o período de criação, 42 dias de idade. Foram avaliados desempenho, digestibilidade (18 a 21 dias), rendimento de carcaça e histomorfometria da mucosa intestinal (18 e 42 dias de idade). Os resultados foram submetidos a análise de regressão polinomial e as médias comparadas pelo teste Scott Knott (0,05). Houve efeito da suplementação de glutamina somente no período pré-inicial para a conversão alimentar, sendo o melhor nível de adição na ração de 1%. Os resultados para o desempenho até 42 dias de idade, rendimento de carcaça e digestibilidade dos nutrientes da ração indicaram que não houve diferença (P>0,05) entre os níveis de glutamina nas rações. Na histomorfometria aos 18 dias de idade foi observada diferença para profundidade de cripta na mucosa intestinal (duodeno, jejuno e íleo) (P<0,05), sendo que para duodeno e íleo o melhor nível de inclusão de glutamina foi 2% e para jejuno 1%. Para os resultados de histomorfometria aos 42 dias de idade, houve efeito dos níveis de glutamina para profundidade de cripta no duodeno, jejuno e íleo, sendo os melhores níveis encontrados de 1, de 0,5 e 2 % respectivamente. Recomenda-se a adição de 1% de L-glutamina na ração pré-inicial considerando a melhora na conversão alimentar no período de 1 a 7 dias de idade e no melhor desenvolvimento da mucosa intestinal.

This experiment was carried out using 504 one-day-old Hubbard female chicks, in order to evaluate the effect of a mixture of organic acids added to the ration, on the control of Salmonella in birds experimentally confronted with S. enteritidis and S. enteritidis associated with Eimeria tenella. The birds were distributed following a totally randomized sequence in factorial way 3x2, added or not the organic acid to the ration and the presence of challenge with S. enteritidis and E. tenella, isolated S. enteritidis or without challenge at all, totalizing six treatments with six repetitions each one, using 14 birds by experimental unit. The statistic data was analyzed using the program SAS, adopted to compare the averages, the Tukey test (quantitative variables) and Kruskal-Wallis (qualitative variables) to p< 0,05. The birds that received organic acid enriched ration had improvement in the performance at 7, 21 and 28 days. The birds inoculated only with S. enteritidis and the birds inoculated with S. Enteritidis and E. tenella presented worse levels of zootecnic performance (p<0,05) at 21, 28 and 35 days of life. The spleen weight and the thin intestine and cecum pH were not influenced (p>0,05) by the addition of organic acids to the ration. All the treatments challenged with S. enteritidis and which received acids presented minor frequency of bacteria isolation in the analyzed organs. It was also observed a reduction on the number of oocists of E. tenella in the excretes and in the cecum content in the treatments which had organic acids, as well as reduction of intestinal damage scores caused by infection with E. tenella. The organic acids promoted improvement on the zootecnic performance on cut chicken, improving intestinal health with positive consequences on control of S. enteritidis together with Eimeria tenella
Foi conduzido um experimento utilizando-se 504 pintainhas de um dia, de linhagem comercial Hubbard para corte, com o objetivo de avaliar o efeito de uma mistura de ácidos orgânicos adicionada à ração, no controle da Salmonella em aves experimentalmente desafiadas com S. Enteritidis e S. Enteritidis associada à Eimeria tenella. As aves foram distribuídas seguindo-se um delineamento inteiramente ao acaso em esquema fatorial 3x2, com a adição ou não de ácido orgânico na ração e a presença de desafio com S. Enteritidis e E. tenella, S. Enteritidis isolada ou sem nenhum desafio, totalizando seis tratamentos com seis repetições cada um, utilizando-se 14 aves por unidade experimental. Os dados estatísticos foram analisados empregando-se o programa SAS sendo adotado para comparação entre as médias, o teste de Tukey (variáveis quantitativas) e Kruskal-Wallis (variáveis qualitativas) para p<0,05. As aves que receberam ração contendo ácidos orgânicos apresentaram melhorias no desempenho zootécnico aos sete, 21 e 28 dias. As aves inoculadas apenas com S. Enteritidis e as aves inoculadas com S. Enteritidis e E. tenella apresentaram piores índices de desempenho zootécnico (p<0,05) aos 21, 28 e 35 dias de vida. O peso do baço e o pH do intestino delgado e dos cecos não foram influenciados (p>0,05) pela adição de ácidos orgânicos na ração.Todos os tratamentos desafiados com S. Enteritidis e que receberam ácidos apresentaram menor freqüência de isolamento da bactéria nos órgãos analisados. Foi também observada redução no número de oocistos de E. tenella nas excretas e no conteúdo cecal nos tratamentos que receberam ácidos orgânicos, bem como redução dos escores de lesão intestinal provocadas pela infecção por E. tenella. Os ácidos orgânicos promoveram melhorias no desempenho zootécnico dos frangos de corte, beneficiando a saúde intestinal com reflexos positivos no controle da Salmonella Enteritidis juntamente com a Eimeria tenella

Abstract:
Coccidia are obligate intracellular parasites belonging to the phylum Apicomplexa. Many coccidia are of medical and veterinary importance such as Cystoisospora species and Toxoplasma gondii. The need to discover new anticoccidial therapies has increased due to development of resistance by the parasite or toxicity issues in the patient. The goals of this work were to develop a model for canine coccidiosis while proving that Cystoisospora canis is a true primary pathogen in dogs and to determine the efficacy of a new anticoccidial agent. A canine coccidiosis model would be useful in evaluating new anticoccidial treatments. Oral infections with 5 X 104 (n=2) and 1 X 105 (n=20) sporulated C. canis oocysts were attempted in 22 purpose bred beagle puppies. Clinical signs associated with disease were observed in all dogs. Bacterial and viral pathogens were ruled out by transmission electron microscopy (TEM) and bacterial growth assays. Development of C. canis in cell culture was also evaluated. The efficacy of ponazuril, a new anticoccidial drug, was examined in T. gondii. In vitro studies were conducted to determine the activity of ponazuril on tachyzoites and how this agent affects development of apicomplexcan parasites. The tachyzoite production assay was conducted. Ponazuril at a dose of 1.0 µg/ml had a significant affect on tachyzoite reproduction. Comparisons were made on how ponazuril affects T. gondii and Neospora caninum. Inhibition of T. gondii tachyzoites occurred after the second round of replication and with N. caninum tachyzoites after 4 rounds of replication. Results of TEM revealed ponazuril affects replication of T. gondii and N. caninum differently. The efficacy of ponazuril to prevent and treat acute and chronic toxoplasmosis was investigated. Mice treated prophylactically with ponazuril were completely protected from developing an acute T. gondii infection. Fatal toxoplasmosis was prevented in mice starting treatment 3 and 6 days post infection at a dose of 20 mg/kg. Immunohistochemistry was used to evaluate ponazurilâ s effect on chronic toxoplasmosis. Sections of brain were scored according to the number of tissue cysts present. Ponazuril also proved to be highly active against toxoplasmic encephalitis in an interferon-gamma knockout mouse model.

Abstract:
Coccidian parasites of the genus Eimeira cause coccidiosis in farm animals, which develop in both the small and the large intestines. Coccidiosis is a major economic concern in many livestock, especially in young animals, as a result of losses caused by clinical infection (diarrhea) and subclinical (poor weight gain in particular) and the required treatment costs. Herein, we summarize geographical distribution of Eimeria parasites, their life cycle, pathogenesis, clinical signs, economic losses due to coccidiosis, diagnosis, recent information on control and prevention, and anticoccidial drugs for Eimeria infection in goats. With regard to poverty alleviation in most developing agricultural countries, it is important to maintain and develop goat-related industries. Proper management should be used to prevent losses and reduce the productivity from coccidiosis in young animals by: reducing the level of environmental contamination by infectious oocysts; minimizing stress; and avoiding overcrowding.
