Determination of the Nucleotide Sequences of Heat Shock Operon groESL and the Citrate Synthase Gene ( gltA ) of Anaplasma ( Ehrlichia ) platys for Phylogenetic and Diagnostic Studies

The 1,670-bp nucleotide sequence of the heat shock operon groESL and the 1,236-bp sequence of the citrate synthase gene (gltA) of Anaplasma (Ehrlichia) platys were determined. The topology of the groEL- and gltA-based phylogenetic tree was similar to that derived from 16S rRNA gene analyses with distances. Both groESL- and gltA-based PCRs specific to A. platys were also developed based upon the alignment data.
