咽頭の淋菌およびクラミジア感染者がどのくらい存在するかを調べるために, 当科および性感染症クリニック受診者のうち2005年11月からの6ヵ月間に咽頭の淋菌とクラミジアを検査した者を対象とした検討を行った. 咽頭スワブまたはうがい液を検体とし, 淋菌はプローブテックと培養, クラミジアはプローブテックとアンプリコアで検出した. 対象は当科12人, 性感染症クリニック543人で, 男性272人 (18～69歳, 平均36.8歳), 女性は283人 (17～55歳, 平均27.9歳) であった. 咽頭淋菌陽性者は男性35人, 女性36人, 咽頭クラミジア陽性者は男性7人, 女性25人で, 陽性者はすべて性感染症クリニック受診者であった.
To evaluate positive rates for gonorrheal infection and chlamydial infection of the pharynx, two pharyngeal specimens, throat washing and throat swab, were obtained from 555 cases visiting an otolaryngology department or a sexually transmitted disease (STD) clinic for 6 months from November, 2005. A nucleic acid amplification test (NAAT), Becton Dickinson strand displacement amplification (SDA), and gonococcal culture were performed for detection of <I>Neisseria gonorrhoeae</I>, and SDA and Roche PCR were performed for detection of <I>Chlamydia trachomatis</I> in the pharyngeal specimens.<BR>The number of cases, who got tested for <I>N. gonorrhoeae</I> and <I>C. trachomatis</I> at the otolaryngology department and at STD clinic, were 12 and 543 during the period. All 555 cases consisted of 283 females ranging in age from 17 to 55 years old (mean, 27.9 years) and 272 males ranging in age from 18 to 69 years old (mean, 36.7 years). The number (percentage) of cases in females to males of with gonorrheal infection and chlamydial infection of the pharynx were 36 (13%) to 35 (13%), and 25 (9%) to 7 (3%), respectively. All the positive individuals were patients at the STD clinic. The results of the study suggested the high degree of detection of cases with a positive result for <I>N. gonorrhoeae</I> and <I>C. trachomatis</I> at the STD clinic, while the number of subjects at the otolaryngology department was considerably less than at the STD clinic.
