Determining the in vitro susceptibility of Neisseria gonorrhoeae isolates from 8 cities in Guangdong Province through an improved microdilution method.

A microdilution method for the antibiotic susceptibility testing of Neisseria gonorrhoeae was established and improved, and the antibiotic resistance of N. gonorrhoeae samples isolated from 8 cities of Guangdong in 2016 was determined. The improved microdilution method was compared with the agar dilution method recommend by the World Health Organization (WHO) Western Pacific Region by testing the susceptibility of 100 clinical N.

Overcoming barriers to health-care access: A qualitative study among African migrants in Guangzhou, China.

Guangzhou is China's third most populous city, and the region's burgeoning manufacturing economy has attracted many young African businessmen and entrepreneurs to the city. The aims of this study were to examine strategies that African migrants in Guangzhou have adopted in response to health-care barriers, and explore their perceptions of how to address their needs. Twenty-five semi-structured interviews and two focus groups were conducted among African migrants residing in Guangzhou, China.

Association of the in vitro susceptibility of clinical isolates of chlamydia trachomatis with serovar and duration of antibiotic exposure.

Background: The presence of persistent Chlamydia trachomatis infection after treatment does not always correlate with in vitro susceptibility testing.

Methods: The in vitro minimum inhibitory concentration (MIC) and minimal bactericidal concentration (MBC) of azithromycin, clarithromycin, roxithromycin, doxycycline, tetracycline, ofloxacin, and penicillin were tested against 61 clinical isolates of C. trachomatis on 6 serovars, and the MIC/MBC of azithromycin and ofloxacin at different points in time after antibiotic administration to infected cultures.

HIV prevalence, incidence and risk behaviours among men who have sex with men in Yangzhou and Guangzhou, China: a cohort study.

Introduction: In China, the prevalence and incidence of HIV among men who have sex with men (MSM) in large-sized cities have drawn much attention. In contrast, there has been a paucity of research focussing on the sexual health of MSM of medium-sized cities. This study fills this important gap in the knowledge by investigating the sexual health of MSM in a medium-sized city (Yangzhou) and a large-sized city (Guangzhou).

Antibiotic susceptibility of Neisseria gonorrhoeae isolates from Guangzhou, China, during 2002-2011.

Antibiotic susceptibility of Neisseria gonorrhoeae in Guangzhou during 2002-2011 showed that resistance to penicillin and ciprofloxacin was high, while ceftriaxone remained effective although there was a trend towards reduced sensitivity.

Expanding provider-initiated HIV testing at STI clinics in China.

Despite expanding sexually transmitted epidemics in South China, the majority of patients presenting to sexually transmitted infection (STI) clinics are not routinely screened for HIV infection. Identifying barriers to offering HIV testing among STI care providers is an important public health priority. The aim of this study was to investigate the frequency of offering HIV testing among STI care providers in South China and reported physician barriers to offering HIV testing.

Prior HIV testing among STD patients in Guangdong Province, China: opportunities for expanding detection of sexually transmitted HIV infection.

Background: Expanding HIV testing is important among individuals at increased risk for sexual HIV transmission in China, but little is known about prior HIV testing experiences among sexually transmitted disease (STD) patients.

Methods: This cross-sectional study of 1792 outpatients from 6 public STD clinics in Guangdong Province recorded detailed information about ever having been tested for HIV infection in addition to sociodemographic variables, health seeking, clinical STD history, and HIV stigma using a validated survey instrument.

Results: A total of 456 (25.

A twin response to twin epidemics: integrated HIV/syphilis testing at STI clinics in South China.

Background: HIV testing is still stigmatized among many high-risk groups in China, whereas routine syphilis testing has been widely accepted at sexually transmitted infection (STI) clinics. This project used the platform of a rapid syphilis screening test to expand HIV test uptake. The objective of this study was to use multilevel modeling to analyze determinants of syphilis and HIV-testing uptake at STI clinics in China.
