**7.4 Clinical findings**

Infections that caused by Cryptosporidium andersoni, are usually asymptomatic, although depressed weight gain in calves and milk yields in milking cows have been reported (Taylor et al., 2007).

In Cryptosporidium parvum infections, clinical signs are characterised by anorexia, depression, weight loss, diarrhea, dehydration, high morbidity and possibly death because of dehydration. Cryptosporidium parvum can cause diarrhea in calves 5to15, and in lambs and kids 5to10 days of age (Navarre and Pugh, 2002; Radostits et al., 2008). Relapses of diarrhea are quite common, and Cryptosporidium parvum usually occurs as a component of mixed infections (Navarre and Pugh, 2002).
