Polymerase chain reaction (PCR) phylogenetic trees. The trees were generated using the buffy coat of a 70-year-old female human granulocytic anaplasmosis patient admitted for the chief complaint of fever. a Phylogenetic tree after groEL nested PCR. b Phylogenetic tree after 16S rRNA nested PCR. c Phylogenetic tree after AnkA nested PCR
