I'm having trouble identifying my organism, since all of the dichotomous keys I have looked at are giving me conflicting results. I'm hoping someone can lead me in the right direction. Here are my results (subjective but accurate according to colors/results):
Motility: Non-motile (could be different, but unlikely)
FTM: Facultative anarobe
H2S (KIA): -
Methyl Red: +
Oxidase: +/- (unsure)
Litmus milk: purple, confirms nonlactose fermenter
Thought it could have been shigella, but shigella is citrate AND lysine neg, which contradicts my tests. Any opinions would be helpful.
