Bartonella rochalimae is a recently discovered strain of Gram-negative bacteria in the Bartonella genus, isolated by researchers at the University of California, San Francisco|University of California at San Francisco (UCSF), Massachusetts General Hospital, and the United States Centers for Disease Control and Prevention.[2] The bacterium is a close relative of Bartonella quintana, the microbe which caused trench fever in thousands of soldiers during World War I.[3] Named after Brazilian scientist Henrique da Rocha Lima,[4] B. rochalimae is also closely related to Bartonella henselae, a bacterium identified in the mid-1990s during the AIDS epidemic in San Francisco as the cause of Cat scratch fever, which still infects more than 24,000 people in the United States each year.[5]
Scientists discovered the bacterium in a 43-year-old American woman who had traveled to Peru for three weeks.[3][1] She suffered from possibly life-threatening anemia, an enlarged spleen, a 102 degree Fahrenheit (39 degree Celsius) fever, and insomnia two weeks after returning to the United States,[6] symptoms akin to those of typhoid fever and malaria.[5] The patient's sickness was first attributed to Bartonella bacilliformis, a known related species with a similar appearance under a microscope that is spread by sand flies and infects 10% of the human population in some regions of Peru with Oroya fever. Antibiotic treatment based on this diagnosis rapidly cured her infection, but further investigation proved the bacteria were of a formerly unknown species. It is possible that other cases diagnosed as Oroya fever result from this species.[2]
The findings were published in the New England Journal of Medicine on June 7, 2007.[1] According to the senior author of the paper, Marryan Gaal, professor of infectious diseases at UCSF, the new discovery is the sixth identified Bartonella species that can infect humans.[2]
