Test results for Bartonella spp. in 296 patients examined by a rheumatologist, Maryland–Washington, DC, USA, August 25, 2008–April 1, 2009*
| Bartonella sp. | IFA–/PCR– | IFA+/PCR– | IFA+/PCR+ | IFA–/PCR+ |
|---|---|---|---|---|
| B. henselae | 196 | 60 | 7 | 33 |
| B. koehlerae | 177 | 65 | 24 | 29 |
| B. vinsonii subsp. berkhoffii | 141 | 145 | 3 | 7 |
| Genotype I | 217 | 75 | 2 | 1 |
| Genotype II | 189 | 101 | 1 | 5 |

*IFA, indirect immunofluorescent antibody results obtained by using B. henselae, B. koehlerae, and B. vinsonii subsp. berkhoffii antigens; PCR, results obtained after PCR amplification by using Bartonella intergenic spacer primers, followed by attempted DNA sequencing of each amplicon.
