Cryptosporidiosis
Cryptosporidiosis, a protozoan disease of the intestinal tract, is caused by Cryptosporidium parvum and Cryptosporidium muris. It infects man, dog, cat, calves, foal, piglets, lambs, rabbit and poultry. The ingestion of protozoan oocysts is the principal mode of transmission. Fever, nausea, anorexia, vomiting, abdominal pain, diarrhoea and dehydration are the important clinical symptoms.
The demonstration of protozoan oocysts in faeces is done for confirmation of disease. Environmental sanitation, control of rodents and personal hygiene can help to reduce the risk of disease. Fluid and electrolytes should be given both by oral and parenteral route to check the dehydration in affected individuals.
