Gastrointestinal diseases are caused by many of the apicomplexan protozoan parasites and cause significant clinical diseases. Cryptosporidiosis is one of the most important diseases of young ruminant livestock, particularly neonatal calves. This study investigates the prevalence of Cryptosporidium infection in Karbala farm cattle. Totally, 1360 fecal samples were collected from cows and calves between (1 week to 5years old) from both genders, from different regions of Karbala. Different fecal examination methods (direct fecal smear, fecal flotation with saturated salt solution and faecal smear stained by modified Ziehl-Neelsen were performed to determine Cryptosporidium spp. oocysts and other mixed parasites in the fecal samples. The results showed that 29.4% of the fecal samples were detected positive for cryptosporidiosis (400/1360). The highest infection rate appeared (41.9%) in the age group from 3-6 months old, and less rate was (15.1%) in 2 years (P≤0.05). Additionally, there was no significant variation found in infection rates between males (33.8%) and females (25.6%). Mixed infections have been reported with Eimeria spp. oocysts (7.3%), Giardia lamblia cysts (1.4%) and Trichostrongylus spp. eggs (5.1%) (P≤0.05). The results indicated the requirement for the eradication of the gastrointestinal parasites by deworming and a good management system in the sampled region.
