Patients can develop two clinical phases: an acute septic phase and a chronic eruptive phase associated with skin lesions. [3] In the acute phase (also known as Oroya fever or fiebre de la Oroya), B. bacilliformis infection is a sudden, potentially life-threatening infection associated with high fever and decreased levels of circulating red blood cells (i.e., hemolytic anemia) and transient ...
It is caused by either Bartonella henselae or B. quintana. [2] B. henselae is most often transmitted through a cat scratch or bite, [3] though ticks and fleas may also act as vectors. B. quintana is usually transmitted by lice. It can manifest in people with AIDS [4] and rarely appears in those who are immunocompetent. [citation needed]

On microscopic examination, the chronic phase and its rash are produced by angioblastic hyperplasia, or the increased rates and volume of cell growth in the tissues that form blood vessels. This results in a loss of contact between cells and a loss of normal functioning. [2] [7] The chronic phase is the more common phase.
Bartonella henselae is a Gram-negative rod. [6] [7] It can be cultured in a lysis-centrifugation blood culture. [8] The presence of bacteria can be detected by Warthin-Starry stain, or by a similar silver stain technique performed on infected tissue. A pan-Bartonella PCR detection is non-invasive and uses blood or biopsies to diagnose. [9]
