One hundred and thirty one strains of Yersinia sp. isolated in Italy from 1979 to 1982 were examined for their ability to produce hemolysis on blood agar. Hemolytic activity was shown by seventy four strains on chicken blood agar and rabbit blood agar with 0.5% lecithin at 28 degrees C. No hemolytic activity was shown at 37 degrees C.

The Authors intent was to study the convenience of exposing selective media for identification of finely atomized pathogenic bacteria such as Staphylococcus aureus, in the proximity of oxidation basins of the mechanical surface aeration-type purification plants, and also to assess the percentage of pathogenic elements spread throughout the air. The Authors consider the use of elective or selective media for the isolation of bacteria in the air hardly important and useful. But since the dishes exposed in the vicinity of the liquid sewage oxidation basin have revealed the presence of polluting aerosols, it would seem convenient to provide for an in-depth study on the mechanism governing the spreading of aerosol particles throughout the air, in relation to the estimate of the meteorological and climatic parameters of the area and to a survey of the persons therein exposed.
