To determine need to culture multiple anatomic sites of homosexual men, we examined 1803 cultures from 791 men who had positive cultures for Neisseria gonorrhoeae from one or more sites. The men were examined during fiscal year 1982 at a health center that serves the gay community. Not included are 184 patients who had positive cultures from the only site tested. Of the 607 patients cultured from two or more anatomic sites, 34 (5.6%) had cultures positive for N. gonorrhoeae from each site, and 492 (81.1%) had N. gonorrhoeae isolated from one site only. Of these 492 patients, 36 (7.3%) had positive cultures from the oropharynx only, 232 (47.2%) from the urethra only, and 224 (45.5%) from the anal canal only. Of 405 patients cultured from the urethra, anal canal, and oropharynx, 92 (22.7%) had N. gonorrhoeae at two or more sites; 313 (77.3%) had the organism at one site only. Of 84 patients cultured from the anal canal and oropharynx only, 11 (13.1%) had positive cultures from the oropharynx and negative cultures from the anal canal. Since it is highly improbable that the infected site will be selected if only one site is cultured, routine culturing of the urethra, anal canal, and oropharynx of homosexual men is necessary for accurate diagnosis.
为了确定对男同性恋者多个解剖部位进行培养的必要性，我们检查了来自791名男性的1803份培养物，这些男性的一个或多个部位淋病奈瑟菌培养呈阳性。这些男性于1982财年在一家为同性恋群体服务的健康中心接受检查。不包括仅在唯一检测部位培养呈阳性的184名患者。在从两个或更多解剖部位进行培养的607名患者中，34名（5.6%）每个部位的淋病奈瑟菌培养均呈阳性，492名（81.1%）仅从一个部位分离出淋病奈瑟菌。在这492名患者中，36名（7.3%）仅口咽部培养呈阳性，232名（47.2%）仅尿道培养呈阳性，224名（45.5%）仅肛管培养呈阳性。在从尿道、肛管和口咽部进行培养的405名患者中，92名（22.7%）在两个或更多部位有淋病奈瑟菌；313名（77.3%）仅在一个部位有该菌。在仅从肛管和口咽部进行培养的84名患者中，11名（13.1%）口咽部培养呈阳性而肛管培养呈阴性。由于仅培养一个部位时极不可能选中感染部位，因此对男同性恋者的尿道、肛管和口咽部进行常规培养对于准确诊断是必要的。
