New selective medium for the isolation of Neisseria gonorrhoeae.
GC-Lect, a new selective medium for the isolation of Neisseria gonorrhoeae which contains five antimicrobial agents, was evaluated with stock cultures and with 500 clinical specimens. With stock cultures, vancomycin-resistant Staphylococcus epidermidis that grew on modified Thayer-Martin medium (MTM) was inhibited on the new medium. Also, vancomycin-susceptible strains of N. gonorrhoeae were mu...
متن کاملCombined selective descriptive medium for the culture of Neisseria gonorrhoeae.
A selective identification medium for Neisseria gonorrhoeae was devised by incorporating antibiotics and a mixture of sugars into a yeast extract agar. The results were compared with those using a standard combined selective/non-selective blood agar medium. Recovery rates of N gonorrhoeae from specimens from 208 patients cultured on both media were comparable, but the selective descriptive medi...
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...
متن کاملNeisseria 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...
متن کاملFurther studies with a selective medium for cultivating Neisseria gonorrhoeae.
A culture medium that is selective for the gonococcus and the meningococcus has been described recently (Thayer and Martin, 1964). The medium with Polymyxin and Ristocetin added permits isolation of the gonococcus from sites highly contaminated with other bacteria. Overgrowth of gonococcal colonies by the commensal bacterial flora present in rectal, vaginal, and cervical specimens is almost com...
