Bartonella spp. in Rats and Zoonoses, Los Angeles, California, USA
Figure A1. Phylogenetic classification of Bartonella spp. genotypes detected in Rattus norvegicus rats in downtown Los Angeles, California, USA, on the basis of citrate synthase (gltA) gene sequences. The phylogram was constructed by using the neighbor-joining method with the Kimura 2-parameter distance model. Only bootstrap values >70% obtained from 1,000 replicates are given. GenBank accession numbers for reference sequences are indicated in parentheses. Scale bar indicates nucleotide substitutions per site. Boldface indicates genotypes identified in rats.
