Increased detection of prolylaminopeptidase in Neisseria meningitidis by Identicult-Neisseria.

Identicult-Neisseria (Scott Laboratories, Inc., Fiskeville, R.I.), a rapid enzymatic method with chromogenic substrates, was tested in our laboratories for the identification of Neisseria gonorrhoea, Neisseria meningitidis, and Neisseria lactamica. The test correlated very highly in its identification of pathogenic Neisseria spp. with modified New York City fermentation medium. Identicult-Neisseria appeared to be more sensitive in its detection of prolylaminopeptidase activity in N. meningitidis than most of the currently available systems.
