weird bacteria update

I also found this source after I posted my other message, that Proteus 
species can also inhabit soil, so you may have a non-clinical type of 
Proteus. We deal mostly with Proteus mirabilis and Proteus vulgaris in 
clinical specimens, and they are a pain because they swarm and cover all 
the other bacteria in a specimen. Selective media of different types are 
used to separate the bacteria from each other. Sometimes the Proteus are 
very resistant and all efforts to separate gram positive bacteria out 
from the gram negatives just doesn't work, even with media like CNA 
(Columbia based blood agar with Colistin and Naladixic acid added as 
antibiotics to suppress the gram negatives).

Good luck with your bug.
