GrapeTree view showing MLST phylogenetic relationship among Chlamydia psittaci strains in study of 3 fatal gestational psittacosis cases (FO-01, YO-02, and NO-03) caused by C. psittaci strains belonging to closely related MLST lineages, Japan, 2017–2024. A) ST; B) country; C) source host. Strains include ST269/ST335. Numbers in parentheses indicate number of isolates. The MLST alleles are concatenated, and the ST is determined using the Chlamydiales database hosted at https://pubmlst.org/chlamydiales. MLST, multilocus sequence typing; ST, sequence type.
