Neuraminidases of Bacteroidaceae die neuraminidasen von bacteroidaceen.

Neuraminidases can be detected in members of the anaerobic gram-negative non-sporing rods (Bacteroidaceae), especially in the genus Bacteroides. B. fragilis, the most virulent species, has the highest neuraminidase activity, while the other intestinal species exhibit markedly lower activities or the enzyme is completely absent. Members of the Bacteroides oralis group, so far investigated, degrade only substrates of lower molecular weight.
