Abstract
Sulfamethoxazole-trimethoprim blood agar (SXT-BA), neomycin blood agar (NEO-BA) and plain sheep blood agar plates (SBA) were compared for isolating group A streptococci in 1,954 throat cultures. SBA and SXT-BA had similar isolation rates (approximately 75% of all positive isolates). NEO-BA was significantly better (87% recovery). A combination of any two media gave 92-95% recovery of group A streptococci from throat specimens.
摘要
在1954份咽喉培养物中，比较了磺胺甲恶唑-甲氧苄啶血琼脂（SXT-BA）、新霉素血琼脂（NEO -BA）和平板羊血琼脂（SBA）用于分离A组链球菌的效果。SBA和SXT-BA的分离率相似（约占所有阳性分离株的75%）。NEO -BA的效果显著更好（回收率87%）。任意两种培养基联合使用时，从咽喉标本中分离A组链球菌的回收率为92%-95%。
