Cryptosporidium infection is a zoonotic disease caused by Cryptosporidium spp. and transmitted by faecal-oral cycle. Young animals are most likely to develop symptomatic infections and shed high quantities of infective oocysts. But infection in adult animals is asymptomatic and number of oocysts shed is usually very fewer than from young animals. (Bukhari and Smith, 1999). The aim of present study was to investigate the prevalence of Cryptosporidium spp. in Turkish Van Cats.
