Abstract

Macrolide-resistant Bordetella pertussis emerged in Vietnam during 2016−2017. Direct analyses of swab samples from 10 patients with pertussis revealed a macrolide-resistant mutation, A2047G, in the 23S rRNA. We identified the MT104 genotype of macrolide-resistant B. pertussis (which is prevalent in mainland China) and its variants in these patients.

Highlights

  • Macrolide-resistant Bordetella pertussis emerged in Vietnam during 2016-2017

  • We identified the MT104 genotype of macrolide-resistant B. pertussis and its variants in these patients

  • Macrolides are commonly used to treat pertussis, but macrolide-resistant B. pertussis (MRBP) strains have been observed in mainland China and Iran (1–4)
