fundet ved fugle. V: Schizogoni H: Gametogony |
Eimeria tenella- Blindtarmcoccidier hos fjerkræ V: Schizogony is predominant 4-5 days after infection with many schizonts. The first schizogony phase is characterized by small round cells named meronts. The second schizogony phase is characterized by numerous elongate crescent shaped cells, named merozoites. H: Gametogony is predominant with many gametocytes and oocysts. Two types of gametocytes: 1) Macrogametocytes (female) with a big central nucleus surrounded by coronal granula. 2) Microgametocytes containing microgametes. And finally syngamy resulting in formation of zygotes transforming into oocysts (rounded greyish cells between the epithel cells) when covered with shell material. Hosts: Poultry. Location: Epithelial cells of the caeca. |
