In 1878, Pasteurella multocida was discovered in birds infected with cholera. Then in 1880, Louis Pasteur isolated it. P. multocida is a small, gram-negative bacterium. It is non-motile coccobacillus and penicillin-sensitive. It can cause infections in humans, as a result of cat or dog bites and scratches. Mammals and birds have it as part of their normal respiratory microbiota and display infections. P. multocida live in the upper respiratory tract of many vertebrate hosts. These include cats, dogs, rabbits, cows, pigs, and fowl. The host species provides these bacteria with nutrients, and if the bacteria are present in an external environment, it is only temporary. This bacteria is located in a wide range of environments. Cholera outbreaks are usually reported in the United States in north central California, the MidWest, and the Muleshoe National Refuge in Texas. | |||

Genome structure
Describe the size and content of the genome. How many chromosomes? Circular or linear? Other interesting features? What is known about its sequence? Does it have any plasmids? Are they important to the organism's lifestyle?
Cell structure and metabolism
Describe any interesting features and/or cell structures; how it gains energy; what important molecules it produces.
Ecology
Describe any interactions with other organisms (included eukaryotes), contributions to the environment, effect on environment, etc.
Pathology
How does this organism cause disease? Human, animal, plant hosts? Virulence factors, as well as patient symptoms.
Application to Biotechnology
Does this organism produce any useful compounds or enzymes? What are they and how are they used?
