  "abstract": "Background: Bartonella species are vector-borne zoonotic pathogens responsible for a wide clinical spectrum of human infections, ranging from asymptomatic or subclinical presentations to self-limiting illnesses and severe, potentially life-threatening diseases. However, data on human infections caused by many newly described or lesser-known Bartonella species remain scarce or entirely lacking.\n\nCase presentation: We report two cases of lymphadenopathy caused by Bartonella species which are genotypically closely related with Bartonella gabonensis and “Candidatus Bartonella gerbillinarum”, in southern Iran. Bartonella DNA was detected in lymph node biopsy specimens using PCR-based assays. Both patients responded favorably to a combination of antibiotic therapy and surgical management, resulting in complete clinical recovery.\n\nConclusions: These rodent-associated Bartonella species have not previously been documented as human pathogens in clinical settings. Our findings raise significant concerns regarding the potential emergence of rodent-borne bartonellosis and underscore the need for heightened surveillance and further investigation within a One Health framework.\n\nClinical trial number: Not applicable.\n\nSupplementary Information: The online version contains supplementary material available at https://doi.org/10.1186/s12879-026-13964-6.",
