Abstract: Three types of lesion were identified and examined by light microscopy and by transmission and scanning electron microscopy: flat oocyst patches, raised oocysts patches and polyps. They all contained heavy concentrations of gamonts and oocysts of Eimeria bakuensis (syn. E. ovina). Small meronts were also present in small numbers. Cryptosporidium, where present, appeared to favour the intestinal wall rather than the polyp. The bases of polyps were saturated with small undifferentiated parasites, most of which were binucleate. Polyps appear to arise from oocyst patches as a result of the parasite's stimulating host cell replication and synchronizing its own division with that of the host cells. Resolution of the lesion appears to be brought about by macrophages destroying infected cells in the polyp base. |
