Pasteurella multocida

Pasteurella multocida is a Gram-negative, non-motile coccobacillus that is penicillin-sensitive. Pasteurella multocida often exists as a commensal in the upper respiratory tracts of many livestock, poultry, and domestic pet species, especially cats and dogs.

Pasteurella multocida was first found in 1878 in fowl cholera-infected birds. However, it was not isolated until 1880, by Louis Pasteur - the man in whose honor Pasteurella is named.
