Penicillinase-producing Neisseria gonorrhoeae: a molecular comparison of 5.3-kb and 7.4-kb beta-lactamase plasmids.

Restriction endonuclease analysis and heteroduplex studies indicate that the only difference between the 5.3-kilobase (kb) and 7.4-kb plasmids from beta-lactamase-producing Neisseria gonorrhoeae is that the latter is the 5.3-kb plasmid with a 2.1-kb insertion. The insertion is bounded by inverted repeats of approximately 300 base pairs. Several plasmids from beta-lactamase-producing N. gonorrho...

Penicillinase-producing Neisseria gonorrhoeae in the Netherlands: epidemiology and genetic and molecular characterization of their plasmids.

Penicillinase-producing Neisseria gonorrhoeae strains were isolated in the Netherlands with increasing frequency during the period of 1976 to 1979. About 3% of the gonococci isolated in the first half of 1979 produced penicillinase. In contrast to the period of 1976 to 1977, most penicillinase-producing N. gonorrhoeae infections during the period of 1978 to 1979 were contracted in the Netherlan...

Rapid penicillinase paper strip test for detection of beta-lactamase-producing Haemophilus influenzae and Neisseria gonorrhoeae.

A modified 1-min iodometric paper strip test for penicillinase activity was developed for detection of beta-lactamase-producing isolates of Haemophilus influenzae and Neisseria gonorrhoeae. The test is simple to perform and uses reagent-impregnated strips that may be stored for 1 year or more prior to use.

Identification of TEM-135 beta-lactamase in penicillinase-producing Neisseria gonorrhoeae strains in Japan.

Ten penicillinase-producing Neisseria gonorrhoeae (PPNG) strains isolated from 2000 to 2008 were characterized by multilocus sequence typing, multiantigen sequence typing, and plasmid typing. Sequence analysis showed that 8 strains contained a TEM-1 beta-lactamase gene. However, two other genetically distinct PPNG strains, isolated in 2004 and 2008, each contained a TEM-135 beta-lactamase on di...

Transfer of beta-lactamase plasmids by conjugation in Neisseria gonorrhoeae.

Conjugation experiments in vitro have been used in an attempt to explain certain epidemiological phenomena seen amongst penicillinase producing Neisseria gonorrhoeae (PPNG) isolated at St Mary's Hospital, London. These include changes in plasmid profiles, a lack of beta-lactamase encoding plasmids in PAOU-requiring strains and a difference in the serological classification of strains of PPNG an...
