Cryptosporidiosis: History, Etiology, Biology, Pathogenesis and Pathoanatomy - A Review

Summary Cryptosporidiosis is a protozoan disease, usually asymptomatic. However, in some cases, the infection can progress to gastroenteritis and, more rarely, to colitis. Intensive studies on the biology of Cryptosporidium started in the 20th century after the outbreak of a major waterborne epidemic. The interest in this parasitosis increased after the WHO identified it as an opportunistic parasitosis - an indicator of AIDS. In this regard, the purpose of this article is to provide a scientific overview of this parasitosis, analyzing the state and development of modern research in a global and national aspect.
