The results of Gram stains and cultures from 145 women with uncomplicated ano-genital gonorrhoea are presented. The site which gave the highest yield of gonococci was the cervix. Equally good results were obtained with Stuart's transport medium and direct plating in the clinic. Positive results from rectal specimens alone were obtained from 8.4% of the 119 women in whom the rectum was examined. In 89 women the results of rectal specimens taken through a proctoscope were compared with those of swabs passed blindly up the anal canal. When Stuart's transport medium was used swabs taken through a proctoscope gave better results than the swabs taken blindly; the latter gave more positive results when direct plating was used. Thus when Stuart's medium is used a proctoscope is essential for the collection of rectal samples. Up to three sets of investigations were carried out where necessary, but 95% of the 145 cases were diagnosed on the results of the first set. However, only 54% of those patients diagnosed at their first visit had positive Gram-stain results. Further refinement of culture results is unlikely to improve diagnostic yield; what is needed is better, rapid diagnosis in the clinic.
本文展示了145例无并发症的肛门生殖器淋病女性患者的革兰氏染色及培养结果。淋球菌检出率最高的部位是宫颈。在诊所中,使用斯图尔特运送培养基和直接接种法均取得了同样良好的结果。在接受直肠检查的119名女性中,仅直肠标本呈阳性结果的占8.4%。在89名女性中,比较了通过直肠镜采集的直肠标本与经肛管盲目插入拭子的结果。当使用斯图尔特运送培养基时,通过直肠镜采集的拭子比盲目采集的拭子效果更好;而直接接种时,盲目采集的拭子阳性结果更多。因此,当使用斯图尔特培养基时,直肠镜对于采集直肠样本至关重要。必要时进行了多达三组检查,但145例病例中有95%是根据第一组检查结果确诊的。然而,在首次就诊时被诊断出的患者中,只有54%的革兰氏染色结果呈阳性。进一步优化培养结果不太可能提高诊断率;需要的是在诊所中实现更好、更快速的诊断。
