[Penicillinase production by Neisseria gonorrhoeae strains isolated from the patients of Dermatology and Wenerology Clinic, Warsaw Medical University in 2006 - 2009].

In recent years the resistance of Neisseria gonorrhoeae to antibiotics is increasing in many countries. The aim of the study was to investigate penicillinase production by Neisseria gonorrhoeae strains isolated from the patients of Clinic of Dermatology and Wenerology WUM in a period between 2006 - 2009. We cultured the bacteria on Roiron medium and we used the iodometric test or BBL Cefinase discs to detect penicillinase. The enzyme was produced by 1,1% of 183, 0,9% of 111, 1,1% of 94 and 0% of 91 of investigated strains, respectively in 2006, 2007, 2008 and 2009 year - on average by 0,8%. This is the lowest result in Europe and one of the lowest in the world.
