Adherence properties of Bacteroides vulgatus, the preponderant colonic organism of adult humans.
Bacteroides vulgatus is the predominant intestinal bacterium of adult humans. The adhesins of this species were studied by using haemagglutination of rabbit erythrocytes and inhibition of this haemagglutination. Eleven haemagglutinating strains were tested after incubation with chicken albumin, bovine serum albumin, human serum fibronectin, fibronectin fragment and N-acetyl neuraminic acid, and after they had been heated, treated with NaIO4, trypsin and D(+)-mannose. Rabbit erythrocytes treated with neuraminidase served as controls. Four different types of adhesins could be distinguished as characterized by different substrate specificities.
