Effects of route of inoculation on the site of development of Caryospora bigenetica (Apicomplexa: Eimeriidae).
The sites of infection by Caryospora bigenetica in Swiss-Webster mice (Mus musculus) were demonstrated after 7 routes of inoculation: oral, intraperitoneal, intravenous, intramuscular, subcutaneous, dermal, and intraocular. All mice exhibited clinical signs of dermal coccidiosis 9 days after inoculation regardless of the inoculation route. Signs included swelling of the facial tissue, footpads, and scrota (male mice). Developmental stages of the parasite were found in the muzzle, tongue, footpad, lumbar subcutaneous tissue, biceps femoris muscle, conjunctiva, and eye; the latter 3 sites represent new sites of development. The site of development of the parasite in the host tissue was independent of experimental inoculation route.
