[On the incidence of pathogenic staphylococci in feces of persons employed in the foof industry in the 7-year period of 1966-1972 in the province of Milan].

An inquiry on the diffusion of the carriers of faecal pathogen staphylococco between the alimentarist people was performed in the province of Milan during 1966-72. Among 29804 persons examined, 1374 carriers of staphylococci were detected with a frequency of the 4.61 per cent. The strains of isolated staphylococci were with the test of the mannite, coagulase and hemolysins alpha and beta classified as 170 pathogens (12.37 per cent), 511 partially pathogens (37.19 per cent) and 693 non pathogens (50.44 per cent). The strains were sensibles to Rifamycin, Nalidixic Acid, Gentamycin, Kanamycin, and much resistent to the Sulfametoxazin and Ampicyllin.
