''P.multocida'' is a species of the [[:Category:Pasteurella and Mannheimia species|''Pasteurella'']] genus. It forms large, grey colonies on blood agar and is not haemolytic. It does not grow on MacConkey. It has five capsular serotypes, A,B,D,E and F and can be a primary and secondary pathogen. It is responsible for secondary infections following primary viral and mycoplasmal infections, especially in the lungs, for example during [[Enzootic Pneumonia - Calves|Enzootic pneumonia of calves]] and pigs. It can cause [[The_Pathophysiology_of_Haemorrhagic_Disease#Vascular_Fragility|vascular fragility]], leading to haemorrhagic disease. It is also involved in [[Bacterial skin infections - Pathology#Subcutaneous abscesses|subcutaneous abscesses]] due to cat bites.
