Which bacilli are gram positive oxidase negative and catalase positive?
Streptobacillus is a gram negative, oxidase negative, catalase negative, non motile organism, and 0.3-0.7 µm by 1-5 µm in lengthEscherichia coliMost of the Enterobacteriaceae are Catalase Positive. E. coli is Catalase Positive and Oxidase Negative. Do not report the previous as an answer.
