Diagnosis of 22 new cases of Bartonella endocarditis

Article Abstract:

The Bartonella species of bacteria may be responsible for a significant number of infections of the heart and its valves. Researchers analyzed the blood of 22 patients from France, England, Canada, and South Africa with endocarditis, an infection of the inner layer of the heart. All 22 patients were diagnosed with endocarditis, with five infected with Bartonella quintana, four with B. henselae, and 13 with other Bartonella infections. Nineteen patients had heart valve surgery; six patients died. Risk factors included homelessness, alcoholism, and owning cats.
