Growth pattern and cell division in Neisseria gonorrhoeae

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...

The changing pattern of antibiotic resistance of Neisseria gonorrhoeae.

A Study Of The Antimicrobial Susceptibility Pattern Of Neisseria Gonorrhoeae

Background and objectives: Rapidly emerging antimicrobial resistance of Neisseria gonorrhoeae isolates to currently recommended antibiotics is a setback for effective treatment and control of disease. This study was carried out to determine the antimicrobial susceptibility profile in the isolates obtained from female sexual workers and male patients attending STI clinics in Hyderabad. Materials...

In vitro inhibition of Neisseria gonorrhoeae growth by strict anaerobes.

Thirty two anaerobic bacterial strains were screened for their in vitro inhibitory activity toward 21 Neisseria gonorrhoeae strains, including two penicillin-resistant strains. From this screening, six anaerobic bacteria belonging to the genera Bacteroides, Peptostreptococcus, and Eubacterium were selected for their large antigonococcal spectrum of activity. The inhibitory activity of these six...
