Clark...and his colleagues have found two species of Lyme disease bacteria previously unknown to infect humans in patients. These two Lyme disease species, Borrelia americana and Borrelia andersonii

From Jacksonville's WJCT: "Clark and his team identified lone star ticks removed from humans who tested positive for Lyme bacteria, including the species of Borrelia burgdorferi already known to cause the disease in North America. Some of the ticks removed from the patients tested positive, too."

ALSO FROM SAME STUDY....

"Clark...and his colleagues have found two species of Lyme disease bacteria previously unknown to infect humans in patients. These two Lyme disease species, Borrelia americana and Borrelia andersonii, were found in symptomatic patients living in the Southeastern United States. The commonly found lone star tick, formerly believed by many to be incapable of transmitting Lyme disease, was implicated in some of these cases."
