Question	Answer		Article
Identify this parasite.	An oocyst of Isospora felis.		[[|Link to Article]]
How would you manage this case?	Infection with Isospora is extremely common, particularly in kittens. Although Isospora can be a primary pathogen, in the majority of cases a self-limiting infection occurs in the absence of any clinical signs. A heavy infection may occur, in association with overcrowding, poor hygiene and stress, and may result in diarrhoea, vomiting, weight loss or poor growth. Where Isospora is identified, it is important to search for other causes of the clinical signs (Salmonella, Campylobacter, Giardia, intussusception, etc.) as the coccidia may be an incidental finding. If numerous oocysts are found in the faeces, and no other cause for the clinical signs is apparent, treatment is recommended with trimethoprim/sulphadiazine (30 mg/kg daily) or furazolidone (8 mg/kg daily), both given for 7–10 days.
