I'm having extreme difficulty identifying this bacteria... here are the results of some of the tests I've performed. Any insight is greatly appreciated!
TTC Motility: strongly motile
Gram stain: negative
Shape: short rods/cocci
O2 requirements: facultative anaerobe
Temperature requirements: 25°C - 37°C (possibly higher temperatures)
Thioglycolate growth within tube: growth around stab
TSI slant: red (no sucrose or lactose fermentation)
TSI butt: yellow (glucose fermentation)
Methyl Red: positive
Voges-Proskauer: positive
MacConkey: fair growth, no colour
Preferred growth media: TSA
O/F dextrose: positive
O/F sucrose: negative
O/F xylose: positive
O/F mannitol: negative
O/F lactose: negative
O/F glucose: positive
Oxidase: negative
Catalase: positive
Gelatinase: negative
Urease: positive
Nitrate reduction: positive
Arginine: positive
Citrate: negative
Lysine: negative
Ornithine: positive
Casein: negative
Starch: negative
**Edit: I've gone through Bergey's Manual of Determinative Bacteriology 9th volume, and there are bacteria that have very similar characteristics, but I've found nothing to match perfectly. I believe it's somewhere in group 5, but have yet to find a bacteria that has everything I'm looking for. Usually, the VP and citrate tests are off.
Whatever happened to your Bergey's Manual of Determinative Bacteriology? Better still, go on and sequence it except you want to work on speculations.

It's very odd that you have chosen the longest and the oldest way to identify one bacterial strain!? it's 2020, and vey easily you could do a 16s rDNA sequencing or even a WGS (whole genome sequencing # with only 350 US dollar) to know what is exactly your bacteria?
