Analysis of Neisseria gonorrhoeae for In Situ β-Lactamase Production by Reagent-Impregnated Filter Paper Replica Methods

Reagent-impregnated filter paper replica methods are described which can be used to detect all penicillinase (β-lactamase)-producing Neisseria gonorrhoeae (PPNG) colonies in an entire population of Neisseria gonorrhoeae growing on primary isolation plates. Images
