Cryptosporidiosis is a disease caused by Cryptosporidium parvum (C. parvum) infection which is spread by contact with reservoir hosts, i.e. cattle, sheep and goats or the environment in which these are housed. It is a Zoonotic disease which means it can be spread to humans, particularly from contact with neonatal farm animals.
Most infections are sub-clinical, which means you may not see any signs of disease. Cryptosporidiosis is the most commonly diagnosed cause of calf diarrhoea. Older calves and adult cattle can shed Cryptosporidium parvum and act as reservoirs of infection to young calves. This has management implications: it is important not to mix different age group of calves.
