  • 🧍 According to Bartlett et al. (2022), this species is an established human pathogen. Publication: Bartlett A, Padfield D, Lear L, Bendall R, Vos M. A comprehensive list of bacterial pathogens infecting humans. Microbiology 2022; 168:0.
  • 🧍 Based on genetic and biological differences, Everett et al. 1999 propose three biovars within Chlamydophila pneumoniae: Chlamydophila pneumoniae biovar TWAR (reference strain: TW-183), Chlamydophila pneumoniae biovar Koala (reference strain: LPCon), and Chlamydophila pneumoniae biovar Equine (reference strain: N16). — In the paper by Everett et al. 1999, the type strain is erroneously cited as ATCC VR 2282 (without dash). — Tang J.
