Parasit. Hung. 3. 133-146. 1970 Life Cycles Involving Sexual and Asexual Generations of Eimeria in Gallinaceous Birds Dr. László PELLÉRUY Veterinary Research Institute of the Hungarian Academy of Sciences, Budapest Although a textbook-like presentation of the life cycles of all eimerian parasites of gallinaceous birds is out of question, the reviewer follows the system of textbook descriptions, in order to add in right place all the new informations emerging from recent studies as well as some hypothetic conclusions that might initiate new approaches to one or another problem. Keeping this in mind, I tried to emphasise all details which seemed to be new,but

,naturally

, could not entirely avoid references to some long established characteristics of coccidian development. Life cycles of the eimerian parasites of birds in the order Gallif

ormes differ only in minor details. There is consistently an asexual and a sexual stage or, acc-rding to another school of thought, an endogenous and exogenous stage of development in the life cycle of all Eimeriae

. A single specific eimerian parasite (oocyst), settled in the susceptible avian host, gives rise to several hundreds of thousands of oocysts which, once discharged into the outside world, disseminate and infect further hosts to maintain the species.
