Bartonella is a common coinfection of Lyme Disease...
"Bartonella doesn't always show signs of infection right away. It can become a stealth infection, living and reproducing in blood vessel linings, lymph nodes and various organs until it finally makes the patient feel sick. But this could happen months or years after initial infection."
"It can cause a surprisingly wide variety of symptoms -- fatigue, neurological, rheumatological, vascular, cardiac and others -- such thattwo people could have completely different symptoms."
"Standard lab tests aren't very good, and miss up to half of cases, making it difficult to diagnose. Our medical establishment is really behind the eight ball on this infection."
