For at least 15 years uniform coproscopic methods have been recommended for Polish sanitary-epidemiologic centres. This is expected to result in comparison of results from various regions and development of epidemiologie maps of the country. Hitherto, 4 methods have been advocated: direct smear, decantation, after Rivas and NIH procedures for enterobiosis. Some recent techniques such as PVA, MIF fixation, trichrome staining, MIFC, procedures after Engelbrecht, Kato and Miura are being advanced. The pertinent comparative studies showed that the modifications of the Telemann's method, for instance, after Miyagava (1913) or Rivas (1928) yield results inferior to those obtained by other methods and consequently should be abandoned in the field practice. Quite satisfactory is the method of decantation, for instance with MF-fixed material. For better recognition of Protozoa the recommended method is that of PVA with subsequent trichrome staining. The pepsine-ether method of Engelbrecht is very good, but only for thick shelled eggs of parasites. The method of Kato and Miura is more efficient than an ordinary smear, but far less recommendable as to the yield. The presented views are debatable, and of course the freedom of choice is left for the investigator
