Neisseria gonorrhoeae

Two fi-lactamase-producing strains of Neisseria gonorrhoeae were studied. The substrate profile, molecular weight, and isoelectric point of their ,8-lactamases were similar to those of the TEM-1 enzyme produced by many gram-negative bacilli. The gonococcal f8-lactamase was cell bound during exponential growth and was most likely located in the periplasm. Penicillin hydrolysis was efficient in i...

Neisseria gonorrhoeae

Expression of Type IV pili by the bacteria! pathogen Neisseria gonorrhoeae appears to be essential for colonization of the human host. Several N. gonorrhoeae gene products have been recently identified which bear homology to proteins invoived in pilus assembly and protein export in other bacterial systems. We report here the isolation and characterization of transposon insertion mutants in N. g...

Staphylococcin on Neisseria gonorrhoeae

Phage group 2 staphylococcal strain UT0002 contains a large 56S virulence plasmid with genes that code for both exfoliative toxin and a specific staphylococcin termed Bac R1. Four penicillinase-producing strains and three penicillinsusceptible strains of Neisseria gonorrhoeae were killed by Bac R1. Aftejr 30 min of growth of the penicillin-resistant TR1 strain in 62.5 arbitrary units of Bac R1 ...
