Phylogenetic analysis of Ehrlichia canis trp36 sequences identified in Pakistan and other regions of the world. The figure shows the maximum likelihood phylogenetic tree inferred with nucleotide sequences of the pre-repeat region of trp36. Strains from Pakistan are labeled with asterisks. Ehrlichia chaffeensis trp47, the ortholog of trp36, sequences were used as the outgroup. The analysis involved 28 nucleotide sequences. All positions containing gaps and missing data were eliminated. There were a total of 387 positions in the final dataset. Reliability of internal branches was assessed using the bootstrapping method (1000 replicates)
