“…In this study two cattle species (E. bovis and E. auburnensis) were detected in sheep. These species were observed in previous studies in their specific host, where Ibrajim et al (26) recorded E. bovis 25.84% and E. auburnensis 7.78%, in Saudi Arabia in Subclinical bovine coccidiosis, also Bangoura et al (27) showed E. bovis was more effective and highly pathogenic.…”

Sheep eimriosis is one of the most important and common disease which infects sheep in all ages but it is more effective in lambs. The diarrhea with or without blood is the main signs of infection. Eimeria protozoan required single host to complete its life cycle which pass in different stages including schizogony, gametogony and sporogony. The study was designed for detection of sheep Eimeria species through the molecular method. This study was conducted in Al-Diwanyah province during the winter months of 2019. In which 200 sheep fecal samples were collected and examined traditionally to investigate the Eimeria oocytsts. Ninety-seven samples of highly intensity infection with Eimeria oocysts were selected to subject for DNA extraction process. The extracted DNAs were tested through amplification of internal transcribed spacer 1 (ITS-1) gene by conventional PCR, and then phylogenetic analysis was made to diagnose the sheep Eimeria species. All samples that examined microscopically were showed positive results of infections with Eimeria protozoan. Out of 97 molecularly examined samples, forty-five (46.39%) were given positive result in conventional PCR technique, where Eimeria spp. detected through succeeded amplification of internal transcribed spacer 1 (ITS-1) gene. Then phylogenetic analysis referred to that there are five species of Eimeria confirmed in sheep in Al-Diwanyah province including 6 (33.33%) samples diagnosed as E. ahsata, 4 (22.22%) samples E. weybridgensis, 3 (16.66%) samples E. ovinoidalis, 3 (16.66%) samples E. bovis and 2 (11.11%) samples E. auburnensis. So, the Eimeria protozoan appears as an endemic parasite and can infect sheep with different species in study area. The sheep can infect with both specific and nonspecific species.

“…This finding has been widely observed (Lassen et al 2009; Bangoura et al 2012; Dong et al 2012; Rehman et al 2012), and it is likely that an age-related immune effect occurs for this parasite (Fiege et al 1992). Protective immunity is generally dose dependent and is usually against infection with a homologous species (Rose 1971).…”

Eimeriosis is caused by a protozoan infection affecting most domestic animal species. Outbreaks in cattle are associated with various environmental factors in temperate climates but limited work has been done in tropical settings. The objective of this work was to determine the prevalence and environmental factors associated with bovine Eimeria spp. infection in a mixed farming area of western Kenya. A total of 983 cattle were sampled from 226 cattle-keeping households. Faecal samples were collected directly from the rectum via digital extraction and analysed for the presence of Eimeria spp. infection using the MacMaster technique. Individual and household level predictors of infection were explored using mixed effects logistic regression. The prevalence of individual animal Eimeria infection was 32.8% (95% CI 29.9–35.9). A positive linear relationship was found between risk of Eimeria infection and increasing temperature (OR = 1.4, 95% CI 1.06–1.86) and distance to areas at risk of flooding (OR = 1.49, 95% CI 1.17–1.91). There was weak evidence of non-linear relationship between Eimeria infection and the proportion of the area around a household that was classified as swamp (OR = 1.12, 95% CI 0.87–1.44; OR (quadratic term) = 0.85, 95% CI 0.73–1.00), and the sand content of the soil (OR = 1.18, 95% CI 0.91–1.53; OR (quadratic term) = 1.1, 95% CI 0.99–1.23). The risk of animal Eimeria spp. infection is influenced by a number of climatic and soil-associated conditions.

“…Outro aspecto que chama atenção é o fato de que, apesar de E. zuernii e E. bovis serem relatadas como as espécies mais prevalentes em bovinos, trabalhos realizados no Brasil, Tanzânia, Turquia, Pakistão, Alemanhã, Irã e Estados Unidos (Rebouças et al 1994, Chibunda et al 1997, Cicek et al 2007, Almeida et al 2011, Bruhn et al 2011, Rehman et al 2011, Bangoura et al 2012, Bahrami & Alborzi 2013, Lucas et al 2014, Rodrigues 2014, reportam que E. bovis foi a espécie mais prevalente nos rebanhos. Tais resultados fizeram com que estes pesquisadores descrevessem E. bovis como a mais frequente em bovinos no mundo.…”

Surtos consecutivos ocasionados por Eimeria zuernii em bezerros de corte de uma propriedade do estado de São Paulo

RESUMO: O presente trabalho tem como objetivo relatar surtos consecutivos (Agosto de 2015 e 2016) ocasionado por Eimeria zuernii em bezerros de corte, Canchim e Nelore, com aproximadamente 45 dias de vida, em uma propriedade rural localizada no município de São João da Boa Vista, estado de São Paulo. O primeiro surto foi diagnosticado em um lote composto por 78 bezerros, entre 35 e 55 dias de idade. Dos 78 bezerros, 32 eram Nelore e os outros 46 Canchim. Já o segundo, ocorreu em um novo lote de 66 bezerros (sendo 36 Nelore e 47 Canchim), com idade entre 30 e 45 dias. Alguns animais apresentaram diarreia sanguinolenta e desidratação. Colheitas de fezes de todos os animais (vacas e bezerros) foram realizadas para realização de exame coproparasitológico e quantificação de ovos e oocistos por grama (OPG e OoPG) de fezes de parasitos. Com base nos resultados encontrados neste estudo, é possível afirmar que os surtos consecutivos em bezerros de corte entre 30 e 55 dias de idade, na época seca do ano (agosto), foram desencadeados pelo elevado grau de infecção destes animais por E. zuernii. Analisando os dois anos em que os surtos ocorreram, a presença de sinais clínicos (diarreia sanguinolenta) e a mortalidade de bezerros desencadeada pela eimeriose/desidratação, aconteceram em 8,3% 1,4% do rebanho, respectivamente. Estes resultados destacam a importância em se realizar pesquisas de campo, com o objetivo de se melhor entender a dinâmica de parasitismo de E. zuernii e E. bovis em bezerros com idade inferior a três meses, em função dos motivos já discutidos neste estudo. Além disso, é necessário que se investigue as possíveis fontes de infecção, como a água ingerida pelos animais, para que condutas práticas possam ser adotadas/recomendadas aos proprietários, diminuindo desta maneira os prejuízos ocasionados por surtos de Eimeria spp em rebanhos bovinos.
