Consensus phylogenetic tree showing relations of the FhcD phylotypes uncovered in the present study (in boldface) to previously known FhcD sequences. In parentheses, alternative names are shown (13; the present study). The sequence that was also detected via RT-PCR is marked by an asterisk. The nodes that separate the novel sequences (denoted by gray circles) are supported by bootstrap values of at least 75% in at least two out of three analyses performed (see Materials and Methods).
