ABSTRACT

This research was carried out in order to determine the prevalence of Eimeria spp. Cryptosporidium spp. oocysts and Giardia cysts in calves less than 6 months of age in Van province. For this purpose, fecal samples were obtained from the rectum of 182 calves. Fecal samples (n: 182) were examined with the modified acid-fast technique for Cryptosporidium spp. oocysts. The same samples were examined by zinc sulphate flotation technique for Eimeria oocysts and Giardia cysts. During the laboratory examination of fecal samples, Eimeria spp. oocysts were identified in 22.53% (41/182), Cryptosporidium oocysts in 13.19% (24/182) and Giardia cysts in 9.34 % (17/182) of the dairy calves examined. The rate of infection was 69.78% (127/182). Single infections (45.05%) and mixed infections (24.73%) were identified.
