We report a thorough microbiological analysis of 1,688 lymph node biopsy specimens collected in our bartonellosis reference center. We studied lymph node biopsy samples from patients with suspected regional infectious lymph node enlargement from January 2008 to December 2012. To evaluate a useful strategy for the diagnosis of infectious lymphadenitis, specimens were cultured and subjected to molecular assays. Histologic analysis was done when possible. A total of 642 (38%) biopsy specimens were infected with a bacterial agent, and quantitative PCR (qPCR) was significantly better than 16S rRNA gene PCR (\n            <jats:italic>rrs<\/jats:italic>\n            ) for the detection of\n            <jats:named-content content-type=\"genus-species\">Bartonella henselae<\/jats:named-content>\n            (\n            <jats:italic>P<\/jats:italic>\n            = 0.05),\n            <jats:named-content content-type=\"genus-species\">Mycobacterium tuberculosis<\/jats:named-content>\n            (\n            <jats:italic>P<\/jats:italic>\n            = 0.05), and\n            <jats:named-content content-type=\"genus-species\">Mycobacterium avium<\/jats:named-content>\n            (\n            <jats:italic>P<\/jats:italic>\n            = 0.007).
