The following describes my organisms and the tests I have run:
Motility: nonmotile (subjective but almost certain)
FTM: facultative anarobe
Methyl red: +
H2S (KIA): -
Litmus milk: purple (confirms nonlactose fermenter)
Oxidase: -/+ (uncertain)
I thought it might have been shigella, but shigella is both citrate AND lysine negative, which clearly conflict. Any help from experienced microbiologists (or anyone with knowledge of these) would be appreciated!!!

As far as gas production, unfortunately I forgot to note the indicator inside of the tube when I took it out of the incubator, but I believe there were bubbles inside the tube. Does that make a great difference?
