Abstract

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.
