Urogenital infection due to meningococcus in men and women

Article Abstract:

Gonorrhea is a sexually transmitted disease caused by the bacterium Neisseria gonorrhoeae. Symptoms usually include urethritis (inflammation of the urethra) in men, and vaginal discharge and acute salpingitis (inflammation of the fallopian tubes) in women. This bacterium normally infects tissues in the anogenital area. A closely related bacterium is Neisseria meningitidis, which usually infects the tissues of the nasopharyngeal (nose and throat) area. A few previous reports have indicated that N. meningitidis may infect the urogenital area and cause similar symptoms to those of gonorrhea. This study examined the test results of people suspected of having sexually transmitted diseases who were treated at a clinic in Mexico City. Over a three-year period, 1,540 men and 762 women were tested. Results showed that N. gonorrhoeae was found in 595 men (38.6 percent) and in 77 women (10.1 percent). N. meningitidis was found in 6 men and 3 women (0.4 percent for each). The nine subjects infected with N. meningitidis came to the clinic complaining of gonorrhea-like symptoms and were treated for gonorrhea. In none of the nine cases was N. gonorrhoeae found. These findings demonstrate that N. meningitidis should be considered a sexually transmitted (or transmittable) disease and that persons suffering from gonorrhea-like symptoms should be tested for both bacteria.

Prevalence, incidence, and determinants of syphilis in female commercial sex workers in Mexico City

Article Abstract:

Female prostitutes in Mexico City may have an overall low rate of syphilis infection, but the risk of infection may rise the longer they remain prostitutes. Researchers studied 3100 female commercial sex workers in Mexico City who asked to be tested for HIV at an AIDS clinic. The syphilis infection rate was 8.2%. Women who said they worked the streets had a 10.1% rate of syphilis infection, while women who worked primarily in bars had a 5.6% rate of infection. Risk factors for syphilis infection were age, young age at first sexual intercourse, and length of time as a prostitute. Syphilis infection was 2.2 times higher among women who reported using condoms than among women who said they did not use condoms. While the syphilis infection rate in Mexico City is fairly low, education may prevent an increase.

Hepatitis B markers in men seeking human immunodeficiency virus antibody testing in Mexico City

Article Abstract:

Gay men appear to have a higher risk of hepatitis B infection than heterosexual men. A study of 1,377 Mexican men who were tested for HIV and the hepatitis B virus (HBV) found that 15% of the men were HBV-positive. However, 30% of the gay men men were HBV-positive compared to 4.6% of the heterosexual men. Five percent of the gay men were in the infectious stage of hepatitis B compared to 0.3% of the heterosexual men. Older men were more likely to be HBV-positive than younger men and this was also true for HIV-positive men.
