By use of triple-culture tests of each site, Chlamydia trachomatis was isolated from 112 women: from cervical material from 110, urethral material from 32, and rectal material from 19. Triple swabs provided 89 (81%) of 110 diagnoses of cervical infection; the first swab yielded 65 (59%), the second an additional 15 (14%), and the third an additional nine (8%). Three sets of cervical scrapings provided 102 (93%) of 110 diagnoses of cervical infections; the first scrapings yielded 76 (69%), the second an additional 22 (20%), and the third another four (4%). Of 32 women with positive urethral cultures, the first swab was positive in 28 (88%), and the second in the remaining four. Of 19 women with positive rectal cultures, the first swab yielded 11 (58%), the second an additional five (26%), and the third an additional three (16%). The results show that positive culture results obtained by use of a single swab underestimate the prevalence of chlamydial infection.
通过对每个部位进行三联培养检测，从112名女性中分离出沙眼衣原体：110名女性的宫颈样本、32名女性的尿道样本和19名女性的直肠样本。三联拭子检测出110例宫颈感染中的89例（81%）；第一根拭子检测出65例（59%），第二根拭子额外检测出15例（14%），第三根拭子又额外检测出9例（8%）。三组宫颈刮片检测出110例宫颈感染中的102例（93%）；第一次刮片检测出76例（69%），第二次刮片额外检测出22例（20%），第三次刮片又检测出4例（4%）。在32名尿道培养呈阳性的女性中，第一根拭子检测为阳性的有28例（88%），其余4例第二根拭子检测为阳性。在19名直肠培养呈阳性的女性中，第一根拭子检测出11例（58%），第二根拭子额外检测出5例（26%），第三根拭子又额外检测出3例（16%）。结果表明，使用单根拭子进行培养获得的阳性结果低估了衣原体感染的患病率。
