NAD(+)-glycohydrolase productivity of haemolytic streptococci assayed by a simple fluorescent method and its relation to T serotype

FEMS Microbiol Lett. 1995 May 15;128(3):289-92. doi: 10.1111/j.1574-6968.1995.tb07538.x.

Abstract

The ability of haemolytic streptococci to produce NAD(+)-glycohydrolase was investigated by a fluorescent assay. Enzyme production was found in 31 (91%) of 34 group A, 17 (61%) of 28 group C and eight (27%) of 30 group G isolates. The high producers were found in 22 (65%) of group A, one (4%) of group C and none of group G isolates. The high producers of the group A isolates belonged to T-1, T-3, T-4 or T-12 serotype. These results suggest that NAD(+)-glycohydrolase productivity of streptococci is closely related to specific Lancefield's groups or T serotypes.
