**3. Cultural, Phenotypic and Biochemical Characterization**

*Pasteurella multocida* is one of the most fascinating bacterial pathogens. It is a small, Gram-negative rod or coccobacillary, non-motile, non-spore forming, facultative anaerobe belonging to the family *Pasteurellaceae.* The organism can be identified on the bases of cultural, morphological and biochemical characteristics. The organism is a Gram-negative rod with bipolar staining characteristics, which is non-haemolytic on sheep blood agar, aerobic to facultatively anaerobic and produces indole, oxidase, catalase and produce indole and ferment carbohydrates with slight gas production [13–15].
