Abstract : The electron microscopic study of Rickettsia prowazecki in ultra-thin sections of chick embryo yolk sacs and also of intact rickettsia in stained preparations prove that the structure of the micro-organisms is quite complex. The preparations clearly show a membrane which is heterogeneous in respect to the density of its cytoplasm. In respect to its internal organization and methods of reproduction Rickettsia prowazecki resembles bacteria. In ultra-thin sections there are demonstrated destructive changes of the infected cells of the yolk sac at various stages of rickettsial accumulation. (Author)
