They completed the titer and ruled out valley fever. Babesa has also been ruled out. 3 specialists have no idea what is is. The specialists has a arranged a 15 minute call to the 1 lab to talk about the findings but still no findings on what this is.Babesia wouldn't be something anyone would catch unless they are running a very specific test for it alone -- it has to be specially ordered (and many labs don't even offer it -- I think our sample had to be sent to a vet school lab, not the standard commercial one). It's just not something that's part of a the general search for answers unless a vet happens to think of it.
I believe Valley Fever may also require sending out for a specialty test that only looks for it in particular.
Unfortunately, these shot-in-the-dark diagnostics be keyed to the particular thing they're looking for, so it can start to get expensive, as you won't pick them up with "general" blood work or testing.
Can your vet also call the one in Topanga that had the dog with the rare infection to find out what it was, and whether they sent off blood/tissue for pathology?
About the nails he was checked and the vet said everything was fine he just said maybe he does not like going on walks probably becausewe walk him separate to our bloodhound and they like to stay together. I was asking about if it could have been a rattlesnake and they seem to think its not. This other doctor we took him to is a specialist and he is saying this is something he has never seen before but he wanted to see how to figure it out. From the blood taken yesterday he said the platelets are back up to 108,000 which is out of danger area. He said the red blood cells are now normal which is good. He also said anemia is gone. So he changed Duke off the Doxy and other antibiotics and placed him on a broad based antibiotic type of Amoxicillin because his fever is staying at around 104.7 most the day. We are trying everything this doctor appears up for the challenge and actually listens.About a month ago you had posted question about rattlesnake avoidance, I don’t know the first thing about rattlesnakes but could he have been bitten by a milder species or chewed on a sick or dead one or something. Also you had brought up issues with his nails being painful, was that figured out by a vet, maybe that could be tied in with his temp.
I really hope you get this solved.
