ABSTRACT

Penicillinase producing Neisseria gonorrhoeae PPNG (66 strains have been examined for the presence of plasmids coding for bêta-lactamase. The 3.2 Mdal plasmid was present in 27/66 (41%) of strains. The 4.5 Mdal plasmid was present in 30/66 (45%) of strains. The association 2.6 Mdal 4.5 Mdal plasmids were only present in 9/66 (13.6%) of strains. The cryptic plasmid of 2.6 Mdal was always present.
