Lesion of Doom: How a Parasitic Bacterium Induces Blood Vessel Formation to Cause Lesions

Researchers discovered a bacteria of the genus Bartonella releases a protein, which they dubbed BafA, which stimulates the production of new blood vessels that support bacterial lesions. Bartonella henselae causes cat scratch disease. The findings provide new insight into the mechanisms by which infectious bacteria can produce lesions.
