Resumo
The protozoa of the genus Cryptosporidium sp. are parasites that complete their life cycle on the surface of epithelial cells of the respiratory, gastrointestinal and urinary tracts of mammals, birds, reptiles and fish. Affected animals generally are asymptomatic but gastrointestinal disorders sometimes can be present. Criptoporidiosis is considered a zoonosis. Infected animals, especially cattle, are a source of infection for the environment and humans, because they eliminate large numbers of oocysts in their feces. The symptoms when present is characterized by watery diarrhea, dehydration, abdominal pain, weight loss and death, especially in immunosuppressed individuals, and especially in patients with human immunodeficiency virus (HIV) and children. Therapeutic methods effective to eliminate this agent in animals and humans has not been developed but it is necessary to applied support treatment. Criptosporidiosis is considered by the World Health Organization as an emerging disease. Basic sanitation, use of appropriate methods for the inactivation of oocysts and security of personal hygiene are recommended as Prophylactic methods to minimize the spread of Cryptosporidium. This literature review was aimed at describing the importance of cryptosporidiosis in public health.
