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...

Wheat-germ agglutination (WGA) was used to identify 168 strains of Neisseria gonorrhoeae and 105 strains of other Neisseria species in a routine laboratory. About one-third of the meningococci reacted with the lectin and titres with some organisms varied on repeat testing. The technique is regarded as unreliable for the identification of Neisseria species.

OBJECTIVES To determine the utility of urine-based ligase chain reaction assays for Neisseria gonorrhoeae and Chlamydia trachomatis in (1) the acceptability of such testing to adolescent detainees, (2) the potential use of these tests for identifying asymptomatic infections, and (3) the effectiveness of this approach for ensuring treatment of infected adolescents. DESIGN Cross-sectional scree...

Neisseria gonorrhoeae kháng thuốc là một vấn đề lớn của sức khỏe cộng đồng. Để hỗ trợ công tác điều trị tại Bệnh viện Đại học Y Hà Nội, chúng tôi đã tiến hành nghiên cứu mô tả hồi với số liệu từ tháng 1/2020 đến 5/2022. Qua 183 phân lập gonorrhoeae, tỷ lệ không nhạy cảm hoặc 18,03% ceftriaxone, 41,53% cefixime, 27,87% azithromycin, 98,16% ciprofloxacin và 74,32% tetracyclin. Tỷ đồng nhiễm bệnh ...

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...
