SARCOCYSTIS-LIKE ORGANISMS IN MUSCULATURE OF A DOMESTIC DOG (CANIS-FAMILIARIS) AND WILD DOGS (LYCAON-PICTUS) IN KENYA

Three of six wild dogs (Lycaon pictus) which died of rabies, and one A lsatian dog which died of adenocarcinoma, were found to harbour sarcoc ysts in their cardiac and/or skeletal muscles. The bradyzoites and met rocytes of the cysts were smaller than those seen in a lion infected w ith Microbesnoitia leoni and the common Sarcocystis spp. found in rumi nants. It is proposed that Lycaon pictus is the natural intermediate h ost of the unidentified Sarcocystis-like species.
