may be asymptomatic or have symptoms similar to cat scratch fever and
- Swollen, red marks resembling scratches.
- Visibly swollen lymph nodes
- Complications of the heart, eyes, and spleen.
- Seizures and possible coma induced by encephalitis.
Diagnosis and Treatment
- Clinical signs and a history of exposure are most often used for diagnosis.
- Polymerase Chain Reaction may also assist in diagnosis by detecting the presence of Bartonella species DNA in serum.
CDC Treatment Recommendation
- Infection may resolve without intervention.
- The suggested dose of azithromycin is as follows:
- Adults and Children >45.5kg: 500mg on day 1 and 250mg for 4 days.
- Children < 45.5kg: 10mg/kg on day 1 and 5mg/kg for 4 days.
- Bartonella henselae will infect endothelial cells and white blood cells leading to complications in the eyes, spleen nervous system, kidney, and bones if left untreated.
- A strong immune response typically results in disease symptoms and will resolve within 2-6 months.
