Genetic diversity of Neisseria gonorrhoeae housekeeping genes.
Molecular typing of Neisseria gonorrhoeae strains is an important tool for epidemiological studies of gonococcal infection and transmission. The recently developed multilocus sequence typing (MLST) method is based on the genetic variation among housekeeping genes. As a preliminary investigation for the development of such a method, we characterized the genetic diversity at 18 gonococcal houseke...
متن کاملNeisseria 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...

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...
متن کاملMolecular epidemiology of tetM genes in Neisseria gonorrhoeae.
OBJECTIVE To examine the epidemiology of the tetM gene in Neisseria gonorrhoeae strains with high level resistance to tetracycline (TRNG) using a polymerase chain reaction (PCR) assay. METHODS A single tube PCR was developed which distinguishes between the American and Dutch variants of the tetM gene. Between 1988 and 1995, 518 strains of TRNG (tetracycline MIC > 8.mg/l) were referred to the ...
متن کاملTranscriptional landscape and essential genes of Neisseria gonorrhoeae
The WHO has recently classified Neisseria gonorrhoeae as a super-bacterium due to the rapid spread of antibiotic resistant derivatives and an overall dramatic increase in infection incidences. Genome sequencing has identified potential genes, however, little is known about the transcriptional organization and the presence of non-coding RNAs in gonococci. We performed RNA sequencing to define th...
