尿路感染反复发作者尿液普通培养与L型细菌培养

A Comparison of Ordinary Bacteria and L-Form Bacteria in Urine Culture of Cases of Recurrent Urethral Infection

69例反复发作尿路感染者尿的普通培养和 L 型细菌培养结果表明 ,前者阳性率为2 0 .3% ,而后者为 4 2 .1%。两者有显著差异 ( P<0 .0 5 )。药敏试验表明 ,同一患者尿液标本中的细菌及 L型细菌对药物的敏感性不同。提示反复发作尿路感染患者 ,应同时作尿普通培养和 L型细菌培养 ,并根据药敏结果合理选用抗生药。

Urine samples collected from 69 cases of recurrent urethral infection were studied . All the samples were cultivated both on ordinary media and on L-form media. The result showed that the positive rate in ordinary media was 20.3% and 42.1% in L-form media, with significant difference between the two (P<0.05). The microbial sensitivity test revealed that the sensitivity of the bacteria and L-form bacteria isolated form the urine samples of the same patient tended to be different, thereby suggesting that cases of recurrent urethral infection shuld simultaneously undergo ordinary urine culture and L-form culture and be treated with relevant antibiotics in accordance with the result of microbial sensitivity test.
