Single nucleotide polymorphism phylogeny. Maximum likelihood phylogenetic tree based on SNPs derived from a whole genome alignment. Diamonds on the tree branches indicate bootstrap support > 80. Colors on the right of the tree represent (A) the type of tissue: blue: conjunctival, green: respiratory, red: vascular; (B) country of origin; dark green: Taiwan, green: Belgium, dark blue: USA, light blue: Japan, yellow: Germany, orange: Austria; (C) year of isolation: dark red: 1965, light green: before 1996, orange: before 1992, green: 1983, purple: 1994, white: NA, light red: 1987, dark green: 1998–1999, light blue: 2001, dark blue: 2002, olive: 1998; (D)
tyrP coverage: the gray scale of the tyrP coverage indicates the estimated tyrP copy number from one copy (white) to two copies (dark gray).
