Just back from his latest check-up after the removal of abcesses 2 & 3 and his culture and sensitivity results were back in. They showed the presence of Pasteurella which was completely expected and not a huge issue in the grand scheme of things as it registered susceptible to all antibiotics.
However it also showed a result of Pseudomonas, again, not unusual as it does tend to be a fairly widespread & opportunistic bacteria but what was unusual was it wasn't appearing as a surface infectant rather it was located inside a cross section of the abcess capsule itself which had been taken at the deepest point of the cavity (connecting with the mandible). It is also Penicillin resistant and resistant to all the other antibiotics (bacteriacidal) we have tried. The lab results showed it as susceptible to Baytril :? but given the poor tissue penetration of enrofloxacin it's not going to touch it.
So Mack is now on a Oxytetracycline injetion every third day as the lab indicated the use of a bacteriostatic antibiotic to make the abcess environment inhospitable might halt the growth of the bacteria. However the fact that Pseudomonas is showing a significant factor in Mack's issues has meant we are left with very few options for the long term and it looks like it is almost certainly now a case of control rather than cure.
Oh and to top it off, whilst waiting for our appointment, I noticed the poor little lad has started with a mite infestation.
