Abstract
We isolated and characterized three multidrug-resistant clinical isolates of group B streptococci with reduced penicillin susceptibility (PRGBS) that formed small non-beta-hemolytic colonies on sheep blood agar plates but grew well on chocolate agar plates. They can be overlooked in the bacterial identification step, leading to clinical misdiagnosis and treatment failure.
摘要
我们分离并鉴定了三株对多种药物耐药的B族链球菌临床分离株，这些菌株对青霉素的敏感性降低（PRGBS），在羊血琼脂平板上形成小的非β溶血菌落，但在巧克力琼脂平板上生长良好。它们在细菌鉴定步骤中可能被忽视，从而导致临床误诊和治疗失败。
