Four hundred and sixty-six questing Amblyomma americanum (L.) (Acari: Ixodidae) from Carolina County, VA, and 98 questing A. americanum from Chatham County, NC, were screened by polymerase chain reaction (PCR) for the Bartonella 16S-23S intergenic spacer region.

Two amplicons, ≈270-280 bp, were detected in two ticks from Virginia. Based upon PCR and sequencing, an adult male and adult female tick harbored DNA sequences closely related to Bartonella tamiae (DQ395180).

Bartonella DNA was not detected in A. americanum from North Carolina. Potential transmission ofBartonella spp. by A. americanum should be the focus of future experimental studies.
