[Synantrophic flies and other insects in the area of a hospital and microflora detected on their body surfaces].

During the summer period (June-September) 1988 the authors examined the incidence of synantropic flies and other insects on the grounds of hospital in Prague. By means of isolation tests the microflora of their body surfaces was recorded. A total of 521 flies of 35 species were collected; furthermore 1 wasp species and 1 ant species were found. This material was subjektes to 90 tests, in which 108 strains of 21 species of microbes were isolated. In 96% G-rods were found. The majority of the microbes were intestinal, potentially pathogenic microbes which currently occur in hospital environment. The authors discuss the possible role of flies and other synantropic insects in the mechanism of transmission of the detected microflora.
