Screening for the A2047G mutation by PCR–restriction fragment length polymorphism analysis. The 521-bp fragment of the 23S rDNA gene amplified by PCR from the Bordetalla pertussis clinical isolates (FR4229, FR4930, and FR4991) and controls (A228 and Tohama I) was digested with the endonuclease BbsI. Lanes 1 and 7, M, 100-bp ladder (SM0321; Fermentas, St. Leon-Rot, Germany); lane 2, B. pertussis FR4929; lane 3, B. pertussis FR4930; lane 4, B. pertussis FR4991; lane 5, control B. pertussis A228 (e
