The principal clinical manifestation is a watery diarrhea in young calves that can lead to dehydration and ultimately death of the infected animals No vaccine, limited chemotherapy. First cause of neonatal diarrheal disease (ruminants).

Cryptosporidiosis

Highly prevalent in cattle in France (40-60%). Economical loss for beef and dairy industry

In Humans

Zoonosis: 748 000 case/year US In developing countries: 8-19% of diarrheal disease In developped countries: 1-3% High prevalence in immunocompromised individuals; responsible for 25% of chronic diarrhea One Health issue: by controlling and understanding cattle infection we would be able to control human infection.
