摘要
The aim was to assess the prevalence of etiologic agents of diarrhea in single and mixed infections and their relationship with age in Holstein calves. Fecal diarrheic samples (n=90) were taken to determine the causative agent (E. coli (K99), Salmonella spp., Cryptosporidium spp., Coronavirus, and Rotavirus). Samples tested were positive at least to one pathogen (87.7%), most of the positive cases were mixed infections (62%; P<0.01); from these, affected by two (59%) and by three or more agents (41%; P=0.07). Cryptosporidium spp. and Rotavirus were the most common agents and most of infections occurred during the first two weeks of age.
