I am trying to classify a bacteria that I isolated from
my red eared slider turtle tank. It's tested Gram negative, non-motile,
oxidase negative, but catalase positive and ferments glucose. Under a
microscope it looks cocci/bacilli shaped, but more on the round side . .
The tests you did give pretty typical results for many bacteria. Most
bacteria are catalase positive, many are glucose fermenters and most are
oxidase positive. You have ruled out Pseudomonas however, which is oxidase
positive. Some E. coli are nonmotile, some are motile. Proteus is motile so
that is ruled out also. You will have to do some other tests to be sure.
