Cryptosporidiosis in Neonatal Calves

Abstract

Cryptosporidiosis in calves is an ongoing problem, primarily because of the high prevalence and high morbidity associated with the infection. This article summarizes current knowledge of the host/parasite interactions associated with cryptosporidiosis. The infection process in intestinal mucosa, the pathophysiology of the disease process, and the immune responses initiated in the calf to control the infection are discussed. Methods for diagnosing C. parvum infection, treatments that have been tried, and management controls are also examined.
