[Isolation and description of a new species of Eimeria in rabbits (Orychtolagus cuniculus) : Eimeria pellerdyi P. Coudert, 1977 (Sporozoa, Coccidia)]

Abstract

Several pure isolates of Coccidia have been obtained in coccidia-free Rabbits by methods taking advantage of differences in the duration of their life-cycle and their site of development, as well as by the inoculation of experimentally immunized animals. Among these isolates one has been shown to represent a new species for which we propose the name: Eimeria pellerdyi P. Coudert, 1977. The oocysts of this species are of medium size (21 x 30 mu), without oocystic residual body. The endogenous life-cycle is completed in 10 days. Schizogony takes place in the superficial epithelial cells of the caecum and the colon, and gamogony in the depth of the Lieberkühn's crypts of the same organs. E. perllerdyi seems to be one of the most pathogenic coccidia species in Rabbits.
