چکیده
BACKGROUND/AIM Non-gonococcal urethritis (NGU) is a very common sexually transmitted disease. The etiology of the disease is complex and not completely solved. The aim of this study was to determine the bacteriological finding in the urethra in men with and without non-gonococcal urethritis. METHODS The study group comprised 200 men with symptoms of urethritis. The control group consisted of 60 men without symptoms of urethritis. The diagnosis of nongonococcal infection was made by finding of an increased number of polymorphonuclear leukocytes (> or = 5) under the microscope in a sample of Gram-stain of urethral smear (x 1 000) and without evidence of Neisseria. gonorrhoeae in specimens (negative direct microscopy and cell culture). Bacteriological examination included: direct microscopy with the Gram-stained and methylblue-stained smears of urethral discharges, and cultivation of specimens under the aerobic/unaerobic conditions. In addition to standard bacterial examination and performinig direct imunofluorescence test to detect Chlamydia trachomatis (bioMerieux, France), urethral smears were also examined for the presence of Ureaplasma urealyticum and Mycoplasma hominis by commercially available Mycofast Evolution 2 test (International Microbio, France). The finding of mycoplasmas > or = 10(4) CCU/ml was positive. The data were statistically analyzed using Pearson chi2 and Student t test. RESULTS C. trachomatis was predominant bacterial species found in urethra in men with nongonococcal urethritis. It was isolated alone and/or mixed with mycoplasmas and/or other bacteria in 86 (43.0%) of examinees. There was statistically significant difference in finding of C. trachomatis between the study group and the control group (p < 0.001). U. urealyticum was found in men with NGU: 30.2% were with C. trachomatis and 36.0% were without C. trachomatis (p > 0.05). In 16 (8.0%) men with NGU, C. trachomatis was isolated alone, while in 13.0% examinees it occurred with U. urealyticum. Staphylococcus saprophyticus was isolated in one subject with NGU, alone. Streptococcus agalactiae was found in 1.5% of men with urethritis. Anaerobic bacteria were found in 38 (19.0%) subjects with NGU and in 7 (11.7%) subjects from the control group. CONCLUSION C. trachomatis was predominant bacterial species found in urethra in men with nongonococcal urthretitis. Mixed infections were frequent.

Urethral specimens from 477 men were collected with endourethral swabs and examined for Chlamydia trachomatis by cell culture on McCoy cells pretreated with idoxuridine. Of these men, 141 had gonococcal urethritis, 262 non-gonococcal urethritis (NGU), and 74 showed no evidence of urethritis. Of 118 men with heterosexually acquired gonococcal urethritis, thirty (25 per cent.), and of 23 men with...

Men with non-gonococcal urethritis (NGU) were divided into two groups and treated with either lymecycline or tinidazole; anaerobic cultures were performed before and after treatment. Neither treatment affected the anaerobic flora. However, the men treated with lymecycline were relieved of symptoms and signs, while those treated with tinidazole were not. The anaerobic bacteria found are consider...

Of an unselected group of 159 women attending a sexually transmitted diseases (STD) clinic 20% (32) had symptoms of urethritis. A positive correlation existed between the finding of more than 10 polymorphonuclear leucocytes (PMNL) per high-power field in the Gram-stained urethral smear and the presence of Neisseria gonorrhoeae, Chlamydia trachomatis, and Trichomonas vaginalis. Conversely, these...
متن کاملMycoplasma genitalium: a cause of male urethritis?
BACKGROUND Male urethritis may be caused by mycoplasmas. Since Mycoplasma genitalium has previously been isolated from the urethra of two men with non-gonococcal urethritis (NGU), it was the aim of the study further to elucidate its role by measuring the prevalence of this organism in men with NGU. MATERIAL AND METHODS The polymerase chain reaction was used. Two different sequences of the gen...

Twenty-two men with non-gonococcal urethritis (NGU), 19 with gonorrhoea, and 22 without urethritis were examined for various micro-organisms. Chlamydia trachomatis was isolated from the urethra of 45% of men with NGU, 21% of those with gonorrhoea, but from none without urethritis. Ureaplasma urealyticum but not Mycoplasma hominis was recovered from a larger proportion of men with NGU than from ...
