Taxonomy: f. Eimeriidae Animal: Isospora canis 1 19.jpg Isospora
canis containing 2 sporocysts with 4 sporozoites each from dog
faeces - 38 x 30 microns. It takes 4 days for the oocyst to
sporulate and usually the oocyst is unsporulated when excreted.
The dog becomes infected by ingesting a sporulated oocyst which
excysts in the small intestine releasing 8 sporozoites or by
ingesting a rodent which has the asexual stages in its tissues.
The infection is usually asymptomatic but in heavy infections in
puppies can cause severe watery diarrhoea but often there are
other organisms present too. First Picture | Previous Picture |
