Abstract
It was observed that 10% of urine culture isolates of enterococci tested for antimicrobial susceptibility failed to grow on commercially prepared Mueller-Hinton agar with low levels of thymidine and thymine. All strains could utilize exogenous thymidine and thymine and required only low levels (0.4-microgram disk) to support growth. All thymidine-thymine-requiring strains were resistant to trimethoprim-sulfamethoxazole.
摘要
据观察，在接受抗菌药敏试验的肠球菌尿液培养分离物中，有10%在含有低水平胸苷和胸腺嘧啶的商业制备的穆勒-欣顿琼脂上无法生长。所有菌株都能利用外源性胸苷和胸腺嘧啶，且仅需低水平（0.4微克纸片）即可支持生长。所有需要胸苷-胸腺嘧啶的菌株对甲氧苄啶-磺胺甲恶唑耐药。
