New bacterium discovered in the Amazon is closely related to Andean species that causes human bartonellosis

A new species of bacteria of the genus Bartonella has been found in the Amazon National Park, Brazil. The DNA is similar to that of two other Andean species, B. bacilliformis and B. ancashensis, which cause Carrión's disease. No evidence suggests this new species can cause disease, but further studies are needed.
