Abstract

This study was carried out, during 2011, to determine the prevalence of Eimeria spp. and Cryptosporidium spp. infecting cattle in Kafr El-Sheikh province. Faecal samples (n=698) were examined with flotation technique for Eimeria and modified Ziehl-Neelsen staining technique for Cryptosporidium spp. Oocysts. Eimeria spp. were in 28.94% and Cryptosporidium spp. in 34.1 % . Eleven Eimeria spp. were identified and their prevalence were  E.ellipsoidalis (52.5%), E. cylindrica (34.2%), E. bovis (31.2%), E. zuernii (28.7%), E. subspherica (19.8%), E. alabmensis (6.9%), E. canadensis (3%), E. aubernensis (2%), E. wyomingensis (1.5%), E. brasiliensis (1%) and E.bukidnonensis (1%). Single infection of Eimeria species was found in 47.5% of the animals, while mixed infection of two and three species were found in 52.5% of animals. Cattle are grouped according to their age into four groups: <3, 3-6, 6-9, >9 months. Eimeria spp. infection were detected in 31.4%, 37.1%, 26.7% and 19.0%, while  Cryptosporidium spp. infection was detected in 42.1%. 41.4%, 26.7% and 19% of the calves in the respective age groups. Peak prevalence of Eimeria spp. and Cryptosporidium spp. infection was observed during winter 33.3% and 39.9%, respectively. Eimeria and Cryptosporidium spp. infection were detected in 40.4% and 46.5% of diarrhoeic calves, respectively. There was higher prevalence of infection in diarrhoeic than in non-diarrhoeic calves.
