Can anyone tell me why you should not perform the oxidase test on organisms
grown on certain media. A colleague at work says that it shouldnt be done on
organisms grown on media containing carbohydrate and so should be only done
on organisms grown on a non selective blood plate which is not always
practical in a clinical diagnostic laboratory (time,cost etc). However i
have read that the only limitations for the oxidase test are specifically
concerned with glucose or nitrate containing media. So does this mean that
media such as Maconkey or CLED are in the clear?
