Extended incubation of culture plates was studied to see if the recovery of Bordetella spp. from nasopharyngeal swabs could be improved. Forty-eight Bordetella isolates were recovered from 103 children (overall positive-culture rate, 46.6%) who met the clinical case definition of pertussis. Seven of 44 (16%) B. pertussis isolates and 2 of 4 (50%) B. parapertussis isolates were recovered only after extended incubation of nasopharyngeal cultures up to 12 days.
研究了延长培养平板的孵育时间,以观察是否能提高从鼻咽拭子中分离出博德特氏菌属的成功率。从103名符合百日咳临床病例定义的儿童中分离出48株博德特氏菌(总体培养阳性率为46.6%)。44株百日咳博德特氏菌分离株中的7株(16%)和4株副百日咳博德特氏菌分离株中的2株(50%)仅在鼻咽培养物延长孵育至12天后才被分离出来。
