Phylogenetic analysis of the OmpA protein and ompA gene of Chlamydia psittaci in study of 3 fatal gestational psittacosis cases caused by C. psittaci strains belonging to closely related multilocus sequence typing lineages, Japan, 2017–2024. Red text indicates gestational psittacosis cases from in this study (FO-01, YO-02, and NO-03). A) Circular phylogenetic tree of the OmpA protein of 200 strains. Blue indicates representative C. psittaci strains. B) Phylogenetic tree of the ompA gene of the 3 strains from this study and representative C. psittaci genotypes. Scale bar indicates nucleotide or amino acid substitutions per site.
