Four methods (streak plate, pour plate, selective broth, and direct fluorescent-antibody staining) were evaluated for their ability to detect group B streptococcal colonization in parturient women and their offspring. When colonization was defined as a positive culture by any method from any site, selective broth was the most sensitive method, detecting 100% of colonized mothers and infants at birth and 48 h of age. This method failed to detect only one colonized individual (infant at 24 h of age). The other three methods detected from 20 to 56% of colonized individuals.
评估了四种方法(划线平板法、倾注平板法、选择性肉汤培养法和直接荧光抗体染色法)检测产妇及其后代中B族链球菌定植的能力。当将定植定义为通过任何方法在任何部位培养呈阳性时,选择性肉汤培养法是最敏感的方法,在出生时和48小时龄时检测出100%的定植母亲和婴儿。该方法仅未检测出一名定植个体(24小时龄的婴儿)。其他三种方法检测出的定植个体比例为20%至56%。
