Background:
Rectal gonorrhea in men has been increasing in San Francisco since 1995.
Goal:
The goal was to determine behavioral risk factors associated with rectal gonorrhea (RGC) among men who have sex with men (MSM) by HIV serostatus.
Study Design:
All men reporting receptive anal sex in the last 6 months are screened for RGC, regardless of reported condom use, at San Francisco's municipal sexually transmitted disease (STD) clinic. We surveyed a convenience sample of men screened for RGC at the clinic.
Results:
Among 564 MSM surveyed, 7.1% had RGC. HIV-positive MSM were significantly more likely (relative risk, 3.5, 95% confidence interval, 1.9-5.8) to have RGC. Behavioral risks for RGC infection varied significantly by HIV serostatus. HIV-positive MSM engaging in anonymous sex were at highest risk for RGC infection. Drug use during anal sex was the strongest risk factor for RGC infection among HIV-negative or unknown HIV status MSM.
Conclusion:
Our data suggest that STD and HIV prevention efforts among MSM in San Francisco must consider the role that HIV serostatus plays in acquisition of new infections.

Factors Affecting the Risk of Infection
The integrity and count of the white blood cells help the body resist pathogens and fight infection. When impaired, it reduces the body's resistance to pathogens. The acidic pH levels of the gastrointestinal, genitourinary tracts, and skin create...

Causative Organism
The primary infectious agent causing tuberculosis is Mycobacterium tuberculosis, a slow-growing, acid-fast, aerobic rod that exhibits sensitivity to heat and ultraviolet light. Instances of Mycobacterium bovis and Mycobacterium avium contributing to the development of TB infection are rare.
