Okay ..first I want to apologize ... I dont knowhow I didnt see or comment on this thread before ... my prayers andthoughts go out to you and Izsy!!
Okay from the reading I have done this is what I have gathered..
as stated before this is really only a bacteria you catch if it issomehow purposelyintroduced into your bloodstream, or thosewith a compromised immune system (nursing home patients seemed to bethe most common)
This bacterium is EXTREMELY resilient to treatment and may requiretrials of different antibiotics. It apparently has a very high mutationrate in which it becomes tolerant of the drug youre trying to kill itwith.
It is most common in the form of a lower respiratory infection and isoften confused with pneumonia before proper cutures are done.
one study I read, this bacteria is harbored in Sheep/Pasture/CastorTicks (Ixodes ricinus) so it may be a possibility that while outsideIzsy may have been bitten and this would be the direct introductioninto her bloodstream and rule out a compromised immune system.
Available antibiotics to treat this particular bacteria are (keep inmind this is for ppl so I dont know if it will help with Izsy, but atleast you will know the classes of drugs that kill it and your vet canpossibly relate this to an approved drug for animals):Meropenem (known as carbapenems),Fluoroquinolones(such as Cipro or Levaquin), Mezlocillin (aform of penecillin), and lastly super strong class of antibiotics knownas aminoglycosides .. they are usually injected directly into the siteif infection.
oh yeah and if it helps you vet, let them know it is a gram negative bacillus ..better help in deciding treatments.
hope this helps some !!
