Biological differences between FIM2 and FIM3 fimbriae of Bordetella pertussis: not just the serotype
Matczak S, Bouchez V, Leroux P, Douche T, Collinet N, Landier A, et al.
Microbes Infect
. 2023 May;
25(7):105152.
PMID: 37245862
Introduction: Bordetella pertussis still circulates worldwide despite vaccination. Fimbriae are components of some acellular pertussis vaccines. Population fluctuations of B. pertussis fimbrial serotypes (FIM2 and FIM3) are observed, and fim3...
