Cryptosporidium spp. is a protozoan frequently observed in mammals, with worldwide distribution, that may cause disease in the respiratory and/or digestive tract, with economic loss. In order to find the frequency of Cryptosporidium spp. in lambs aging 0-60 days, four communities in Tlalpujahua, Michoacan, Mexico, were sampled. One hundred and twenty two faeces samples were taken directly from the anus. Samples were processed and stained using ZN for parasite identification. Chi-square test was calculated according to location, age, sex, breed and farm’s type of production. A frequency of 90-100% was obtained, with no statistical difference in variables. It is concluded that high frequency (90-100%) of Cryptosporidium spp. was found using ZN stain in lambs aging 0-60 days in Tlalpujahua, Michoacan, with no difference regarding location, age, sex, breed and production system. |
