[Epidemiologic interrelation among intestinal protozoans by direct count. Statistical analysis of 9,471 examinations and a comparison with the literature].

A statistical study of the results of coprological analysis allows us to appreciate the prevalence of the different parasites, depending on the geographic origin of the outpatients of a hospital situated in the suburbs of Paris. The multifactorial analysis shows, besides other problems, the epidemiological relations between these parasites or, in the contrary, the oppositions which can appear. These results are compared with those published since two decades; their study empowers to set the problem of the fiability of some statistics and, therefore, of the possibilities of an efficient epidemiological research.
