Coccidial colonization of the cecum in the Eimeria infected partridge.  M. DUROJAIYE (1), V. LETKOVA (2), M. GOLDOVA (2), A.T. MARIASSY (3).  (1) Barry University, Miami Shores, FL, 33161, (2) University of Veterinary Medicine, Kosice, Slovakia, and (3) Nova Southeastern University, College Of Medical Sciences, Ft. Lauderdale 33328.  Coccidia cause specific patterns of intestinal lesions that vary with the coccidium and host species.  Experimentally infected partridge chicks were examined at day 1 through day 6 post infection.  Differential counts of parasitic forms were made in H&E sections.  Average counts ranged from 0 to 1000 of the 1^st, 2^nd, and 3^rd generations of schizonts and 0 to 575 gametocytes per cecal section.  A significant double wave of re-infection was observed as indicated by the fluctuation from 525 to 14 to 391 gametocytes at days 4, 6, and 12.  These results support the qualitative observation that coccidia colonize cecum in a progressively intensive fashion unequally.
