Trichomonas vaginalis is one of the pathogens causing sexually transmitted infections. This microorganism is a common pathogen among women, but its significance as a cause of morbidity among men remains uncertain. We sought to determine the prevalence and morbidity of T. vaginalis infection in Japanese men with and without urethritis.
We examined urine specimens from 215 men with urethritis and 98 men without urethritis for the presence of urethral T. vaginalis by PCR assay.
Only four patients-one with gonococcal urethritis, one with non-gonococcal chlamydial urethritis, one with non-gonococcal non-chlamydial urethritis and one without urethritis-were positive for T. vaginalis. The prevalence of T. vaginalis was 1.4% in men with urethritis and 1.0% in men without urethritis. A possible relation between the appearance of T. vaginalis and clinical symptoms was not confirmed.
In the present study, the incidence of urethral T. vaginalis infection appears to be rare in Japanese men with or without urethritis, and T. vaginalis may be an uncommon pathogen in male urethritis in Japan.
阴道毛滴虫是引起性传播感染的病原体之一。这种微生物在女性中是常见的病原体，但它在男性中引起发病的意义仍不确定。我们旨在确定有和没有尿道炎的日本男性中阴道毛滴虫感染的流行率和发病率。
我们通过 PCR 检测法检查了 215 例有尿道炎的男性和 98 例没有尿道炎的男性的尿液标本中是否存在尿道阴道毛滴虫。
只有 4 例患者——1 例淋病性尿道炎，1 例非淋球菌性衣原体尿道炎，1 例非淋球菌性非衣原体尿道炎和 1 例没有尿道炎——阴道毛滴虫检测阳性。尿道炎患者中阴道毛滴虫的患病率为 1.4%，无尿道炎患者中为 1.0%。不能证实阴道毛滴虫的出现与临床症状之间存在可能的关系。
在本研究中，有或没有尿道炎的日本男性中尿道阴道毛滴虫感染的发生率似乎很少见，阴道毛滴虫可能不是日本男性尿道炎的常见病原体。
