A simple method for recovery of Bordetella pertussis is described using phosphate-buffered saline containing a casein hydrolysate for transporting secretions collected by nasopharyngeal aspirate. Bordetella pertussis was reisolated from 92% of clinical specimens held at 4 degrees C for 1 week and from all specimens held at -20 degrees C. This method will facilitate the centralization of laboratory facilities for the diagnosis of pertussis.
