Hello Tania All strains of bartonella can be tested at Himmunitus in Belgium and Galaxy in the USA. I had a bone tumor in '99 and the bone is still not healed, glomus tumor, thrombocytopenic purpura when I was pregnant, my newborn nearly died in IC due to an unknown infection (ahum) in 1995, my face looks as if I have lupus due to overvascularisation caused by bartonella, my bones hurt all the time as well, I lost weight as if I had aids, my chest hurts horribly, ... I tested positive for bartonella in 2008 but the doctor said it was nothing because all other infections (Pfeiffer, CMV, ...) were positive as well. I know now that bartonella deadlocks your immune system and hell breaks loose. My last pregnancy was did the trick. Bartonella got the chance to break out again.
