Frequency of species of the Genus Eimeria in naturally infected cattle in Southern Bahia, Northeast Brazil

Abstract: The aim of this study was to determine the presence of species of the genus Eimeria species in naturally infected bovines in Southern Bahia, Northeast Brazil. The study population comprised 117 Zebu crossbred cattle that belonged to 10 dairy herds with extensive or semi-extensive production systems. The modified Gordon and Whitlock technique was used to determine positive samples and number of oocysts per gram of feces. Statistical analyses were performed using the chi-square test with Yates correction and a 9… Show more

“…Ten species of Eimeria were identified: E. bovis (37.6%), E. zuernii (17.9%), E. ellipsoidallis (17.3%), E. auburnensis (9.5%), E. canadensis (4.9%), E. alabamensis (4.5%), E. subspherica (3.1%), E cylindrica (2.3%), E. wyomingensis (1.9%) and E. bukidnonensis (1.0%). A similar result was found by Rebouças et al (1994), in São Paulo, and Almeida et al (2011), in Bahia. Although E. auburnensis and E. wyomingensis were not identified (respectively), they both mentioned E. brasiliensis.…”

“…These results suggest that in Brazil, E. bovis is one of the most important species because it has repeatedly been found to be the most frequent species in many studies conducted in this country (REBOUÇAS et al, 1994;ALMEIDA et al, 2011;BRUHN et al, 2011). In the south of Minas Gerais, in addition to E. bovis, E. zuernii is also highly disseminated among calves, thus causing concern precisely because these are the species that are considered to be most pathogenic and most frequent among young cattle (TAUBERT et al, 2008;LASSEN et al, 2009 Bianchin et al (1992), Trichostrongylus spp.…”

“…Em 86 fazendas polonesas a prevalência nos animais investigados foi de 80,1% em bezerros de 3 a 9 meses, 18,2% naqueles de um a três meses e 1,7% entre os com 9 e 18 meses (KLOCKIEWICZ et al, 2007 GRISI, 1984;REBOUÇAS et al, 1994;ALMEIDA et al, 2011;BRUHN et al, 2012) Em estudo realizado por Lima et al (1997) em Minas Gerais com bezerros do nascimento aos 27 meses de vida, os animais começaram a se infectar por helmintos gastrintestinais antes dos 2 meses de idade, e apresentaram período crítico dessas infecções até os 18 meses. Neste estudo, a maior ocorrência de eliminação de ovos se deu nos animais com mais de 45 dias de vida, tendo idade média de 64,9 dias.…”
