first episode of NGU, and 1 of 39 with no urethritis. Serum IgM immunofluorescent antibody to chlamydia was demonstrated in 16 of 20 men with chlamydia culture positive NGU, and 3 of 39 with chlamydia culture negative NGU, and none of 34 with no urethritis. 9 of 10 culture positive men with cl10 days symptoms developed immunofluorescent antibody seroconversion in paired sera. U. urealyticum was...

BACKGROUND Several uncontrolled observational studies have suggested that the tetracycline class of antibiotics may not be effective in treating Mycoplasma genitalium infection. The present study compared the efficacy of 1 g of azithromycin given as a single dose with that of 100 mg of doxycycline given twice a day for 7 days in eliminating M. genitalium infection. METHODS Men with signs or s...

BACKGROUND Mycoplasma genitalium is a common cause of nongonococcal urethritis. Treatment trials have shown that doxycycline is inefficient, whereas a 5-day course of azithromycin eradicates the bacterium from 95% of infected men. The aim of the study was to establish the reason for the occasional treatment failures. METHODS Seven M. genitalium strains isolated from men who experienced azithr...

BACKGROUND Nongonococcal urethritis (NGU) is the most common male reproductive tract syndrome. Ureaplasmas spp. including U. urealyticum and U. parvum, have been increasingly reported to be implicated in NGU. However, there are still many contradictions about their pathogenic role in NGU. AIMS The goals of this study were to evaluate the association of Ureaplasmas spp. with NGU, and to compar...
