The role of fimbriae and flagella in the mechanism of attachment of S. typhimurium to poultry skin was examined by using cells with (1) type 1 fimbriae (flagella present), (2) cells from which fimbriae and flagella were removed by physical means, (3) cells grown at 18°C which produced relatively thick, mannose‐sensitive type 1 fimbriae only, and (4) cells grown in the presence of D‐mannose which produced thin, mannose‐resistent fimbriae. When broiler skin was immersed in the above cell suspensions, S. typhimurium cells adhered firmly and equally well in all instances except that fewer cells attached when grown in the presence of D‐mannose. When fimbriated and nonfimbriated cells were spread on broiler skin, thus avoiding effects of water uptake, cells attached, but in lower numbers than when skin was immersed in a cell suspension. It was concluded that bacterial attachment to poultry skin is a complex phenomenon which involves mechanisms other than fimbriae, flagella or water uptake, though a combination of these and other factors may be involved.
