Haemobartonella Felis

I'm not sure why the Vet is not more interested that Bob's Bartonella test came back positive for Haemobartonella Felis or Mycoplasma.

This effects Bob's red blood cells and can really make him sick, even die. He's being treated with Doxy, as mentioned in my last post, but I wonder how much this is putting a strain on Bob and if the treatment will help him feel MUCH improved?

Bob's night in the hospital passed without much incident. He vomited once. Is on his IV. The re-checked ultrasound showed some improvement in his pancreas. At noon, Bob will be sedated, the scary part of his day, and he will have the endoscopy done and biopsies taken. Hopefully, he will wake back up from sedation and be ready to come home later today.

All this has been like reading a mystery novel that's slowly beginning to reveal a thrilling conclusion.

What IS making Bob sick?
