title: Two morphological types of oocyst of rabbit coccidia Eimeria media Kessel, 1929.
abstract: The morphology of oocysts of E. media Kessel, 1929, has been studied and two types have been found. Significant differences were observed in length of the oocysts (average values 29.05 microns with type I and 32.88 microns with type II), in width of the micropyle (5.21 and 3.72 microns, respectively) and in width of the sporocysts (6.67 and 8.00 microns). Marked differences were found even in the shape of the residual bodies of the sporocysts and in the structure of the oocyst wall in the region of the micropyle.
