Prevalence and molecular epidemiological typing of penicillinase-producing Neisseria gonorrhoeae and their bla(TEM-135) gene variants in Nanjing, China.

Background: This study aimed to investigate the prevalence of penicillinase-producing Neisseria gonorrhoeae (PPNG) and their blaTEM-135 gene variant in 2007 and 2012 in Nanjing, China. In addition, molecular epidemiological typing of all isolates was performed to elucidate the genetic relationships of the PPNG strains.

Methods: A total of 199 and 77 N.

Surveillance of antimicrobial susceptibilities in Neisseria gonorrhoeae in Nanjing, China, 1999-2006.

Objective: To monitor the frequency and types of antibiotic resistance of Neisseria gonorrhoeae in Nanjing, China, between 1999 and 2006.

Methods: beta-Lactamase production was determined by paper acidometric testing. Minimum inhibitory concentrations (MICs) to penicillin, ceftriaxone, tetracycline, ciprofloxacin, and spectinomycin were determined by agar plate dilution.

[Epidemiological and bacteriological characteristics of Neisseria gonorrhoeae isolates in China].

Objective: To investigate the antimicrobial susceptibility,auxotype, and plasmid profile of Neisseria gonorrhoeae isolates in China and to provide evidence for the development of treatment guideline and policy for control.

Methods: Agar dilution was used to detect antimicrobial susceptibility. The auxotype was determined by GC genetic medium.

Surveillance of antibiotic resistance of Neisseria gonorrhoeae isolates in China, 1993-1998.

Background: The prevalence of sexually transmitted diseases (STDs) has been increasing in China since the 1980s. Because gonorrhea is the most frequently reported STD there, information on the antimicrobial susceptibility of Neisseria gonorrhoeae will aid in its control.

Goal: To investigate the antimicrobial susceptibility of N gonorrhoeae isolates in China and to provide data for formulation of treatment guidelines and control policies.
