Main Article

Figure 2

Maximum-likelihood phylogenetic tree generated by using the general time-reversible model using discrete gamma distribution for a total of 2,308 bp of the gltA, htrA, ompB, and ompA genes concatenated from a few members of the genus Rickettsia. Diamond indicates isolate obtained from ticks in Mexico. Bootstrap values >50% are indicated at the nodes (−In = −6514.38). Numbers in parentheses are GenBank accession numbers. Scale bar indicates nucleotide substitutions per site. NA, not available.
