Neuraminidase activity of NAG vibrios and of some representatives of the intestinal group of bacteria.

It was studied 203 strains of NAG vibrios and 71 strains of different enterobacteria for the ability to produce neuraminidase. The most frequent neuraminidase producers were found among the strains isolated from humans (99 strain of 131). There was no correlation between neuraminidase production and other properties of the vibrios. The examined strains of the family Enterobacteriaceae did not produce the enzyme.
