Abstract

Summary

The role of neuraminidase in haemagglutination and adherence to colon WiDr cells by eight strains of and four strains of oral black-pigmented gram-negative anaerobes was studied. Neuraminidase treatment resulted in a very small increase of haemagglutination by some of the strains but had no effect on adherence to WiDr cells by all bacterial strains tested except one strain of (HG 110). Inhibition of neuraminidase had no effect on haemagglutination or adherence, nor was any correlation found between haemagglutinating ability and neuraminidase activity in the . strain. The results indicated that haemagglutination and adherence of . to WiDr cells were not mediated by neuraminidase.
