The numbers in parenthesis refer to the proportion of genes/proteins, found in each category, relative to the 874 analyzed genes/proteins. LGV, lymphogranuloma venereum.
a
Genes/proteins for which the phylogenetic tree differentiates at least one group of strains in a nonexclusive manner.
b
Genes/proteins for which the phylogenetic tree differentiates only one particular group of strains whereas the remainder are mixed.
c
Genes/proteins for which the phylogenetic tree shows three clades (ocular, genital, and LGV serovars).
d
Refers to all genital strains (prevalent plus non-prevalent serovars).
e
Genes/proteins for which the phylogenetic tree clusters the strains from prevalent genital and LGV serovars in the same clade.
