Mamalian coccidiosis

Coccidial Protozoa whilst most important in the chicken, can actually affect an entire host range.

• Isospora/eimeria strains. 
• Cattle, sheep, pigs and rabbits.
• Isospora== 2 sporocysts with 4 sporozoites. PPP= longer than eimeria (7 days eimeria). Differentiate by ID cysts. 
• Pathogenic and non pathogenic species.
• Few treatments available.

Sheep:

• Disease in lambs (2-3 months). 
• 10 species.
• Caecum/colon.
• Diarrhoea, dehydration, abdominal pain & anorexia. 
• Diagnose= clinical signs + oocysts. 

Cattle:

• Below 1 year old.
• 20 species.
• Housed, older animals.
• Caecum/colon.
• Dystentery, diarrhoea, and dehydration.
• Sulphonamide treatment. 
• Diagnose by clinical signs/oocysts. 

Pigs:

• Young piglets.
• Isospora suis-> S.I. 
• High morbidity, low mortality. 
• Diagnosis difficult-PM.
• Sow prophylaxis.

Rabbits:

• E.Stiedae.
• Wasting, diarrhoea & jaundice. 
• Bile duct epithelia. Enlarged liver & white nodules
• Diagnose-> PM, oocysts in faeces. 
• Treatment/prophylaxis.

Horses:

• E.Leukarti. 
• Intermittent diarrhoea. 
• Difficult diagnosis. 

Dog 

• Isospora.
• Differential diagnosis.
