Overview
Disease caused by the parasite cryptosporidium.
Diagnosis
- Faecal smear
- Ziehl-Neelson (ZN) stain
- Oocysts stain red against a blue/green background
- Immunoassays
- Detect oocysts in faeces
Control
- Isolate/quarantine bought-in calves
- Treat if signs of diarrhoea present
- Good hygiene, adequate bedding and disinfection of calf pens is important
- Prevention/treatment
- Halofuginone
- Halocur or Intervet
- Oral dosage
- Halofuginone
Villus Atrophy in Enteritis
- Affects calf, lamb, piglet, kitten.
- Increasingly important as part of the neonatal diarrhoea complex in calves.
- Zoonosis.
Pathology
Gross
- Intestines diffusely reddened, with fluid contents.
Histological
- Tiny parasites on surface of epithelium.
- Villus atrophy and fusion.
- Iinflammation (mainly lymphoid) in crypts and lamina propria.
