Conteúdo: 	Abstract: The endogenous development and prepatent and patent periods of Eimeria ninakohlyakimovae were studied in 43 1-3-wk-old coccidia-free kids inoculated with 5.0 x 10(4), 1.5 x 10(5), 2.0 x 10(5), or 9.0 x 10(5) sporulated oocysts/kg. Twenty-five kids were killed at 24- or 48-hr intervals, 2-18 days after inoculation (DAI). Two generations of meronts, gamonts, gametes, and oocysts were found in sections stained with hematoxylin and eosin and examined using under light microscopy. The first generation of meronts developed in the endothelium of the lacteals, in the lamina propria, and in the lymphatic vessels of the ileum submucosa. Mature, first-generation meronts, 165.5 x 123.6 microm, were first found 10 DAI. Second-generation merogony developed in the crypt epithelial cells of the cecum and colon; mature meronts, 16.8 x 11.6 microm, were first seen 12 DAI. Gametogenesis occurred in the cecum and colon epithelium; mature microgamonts (16.1 x 13.0 microm), microgametes, macrogametes (14.7 x 12.5 microm), and oocysts (18.3 x 13.3 microm) were seen at 13 DAI. The course of the infection was followed in 18 kids examined every day until 24 DAI. The prepatent period was 14.7 (13-17) days and the patent period 6.8 (4-10) days. The sporulation time at 30 C, with constant aeration, was 2-3 days.
