Consider a gram-negative pathogen isolated from marine mammals. this pathogen is subjected to a series of tests and found to have the following characteristics:.
a) oxidase-positive,
b) does not hydrolyze urea,
c) produces indole,
d) does not produce acetoin.

Option A and Option C

Explanation:'

A gram negative bacteria is isolated from marine water. They are pathogenic in nature and is found on the body of the marine mammals.

The pathogen is subjected to various types of biochemical tests which includes various tests in it.

The cell membrane of the gram negative bacteria shows the presence of oxidase and is capable of producing indole.

The gram negative bacteria has the ability to produce indole by the IPyA pathway cycle. and also has oxidase in its outer membrane.
