In response to unknown bacteria posted by janz:


You mention that the organism is gram positive but list results for a number of tests commonly used with gram negative bacteria. Have I misunderstood?

What sample was the organism isolated from?
What media was it grown on?
What did it look like growing on the media?
Is it catalase positive?
