Bartonella is inside red blood cells, on its outer membrane and in the water part of blood in capillaries and venous blood and lyme fluid. But these bacteria are also in 60.000 miles of tubing used by capillaries, venous and lymph tubing.
Therefore, Bartonella is in every mm (milliliter) of tissue and blood and lymph tubing.
What does this mean for the issue of symptoms? Bartonella can cause virtually every disease symptom we know. Talking about diagnosis based on large lymph nodes or straia red lines is an error since both are rare.
