  • Title: The pathogenicity of rabbit coccidium Eimeria coecicola Cheissin, 1947.

    Abstract:
    The pathogenicity of Eimeria coecicola for rabbits has been demonstrated in our experiments. The animals suffered from prolonged affection of appendix lasting at least 20 days. Pathological changes appeared with the development of merogony since day 4 post infection (DPI) and were characterized by an inflammatory infiltration and abundant pyogenic component in lamina propria, swelling and coalescence of upper parts of appendix mucosa above atrophied domes, where spaces filled with stagnating inflammatory exudate, endogenic stages of coccidia, and desquamated epithelia are formed. The alteration of the epithelium and exposure of the appendix lamina propria occur in relation with the gametogony in the period of about 10 DPI. Since 8 DPI, the epithelium of the infected endogenic stages of coccidia becomes hyperplastic, proliferates into lamina propria and is subjected to necrosis. Groups of immature oocysts and their fragments remain in lamina propria and are resorbed, at least for 10 days, by granulomatous inflammatory structures with abundant multinucleate cells of the type of foreign body cells.
