(Tshalaia, 1941) Morpho-biological characterization of new strains isolated from the environment, and a review of the literature

After an investigation carried out with samples from several sewage sludges from the town of Pavia (Italy) the AA. report the isolation of two new strains of Entamoeba moshkovskii. The usefulness and reliability of two methods, i.e. growth in hypotonic media and the thermoresistance tests in vitro for the biological typization of this species are analyzed and discussed. Both methods had already proven useful to characterize the Laredo-type strains of E. histolytica too, as reported by other AA
