*Large grey colonies on blood agar
*Not haemolytic
*Do not grow on MacConkey
*Five capsular serotypes, A,B,D,E and F
*Primary and secondary pathogen
*Responsible for secondary infections following primary viral and mycoplasmal infections, especially in the lungs, for example during [[Respiratory Bacterial Infections - Pathology#Enzootic pneumonia of calves|Enzootic pneumonia of calves]] and pigs
* Can cause vascular fragility, leading to [[Haemostasis - Pathology#Haemorrhagic Disease Due To Vascular Fragility|haemorrhagic disease]]
*Involved in [[Bacterial skin infections - Pathology#Subcutaneous abscesses|subcutaneous abscesses]] due to cat bites
*Typa A
**Commensal in upper respiratory tract of animals in UK
**Primary pathogen in avian cholera - a septicaemia in chickens and turkeys
**Secondary pathogen commomly repsonsible for dog and cat bite wound infections in humans and animals
**Feline pyothorax and [[Muscles Inflammatory - Pathology#Abscesses|cellulitis]]
**Some strains involved in [[Nasal Cavity Inflammatory - Pathology#Bacterial rhinitis|Atrophic rhinitis of pigs]], and produce osteolytic toxin
**Involved in [[Respiratory Bacterial Infections - Pathology#In Rabbits|'Snuffles' in rabbits]], a mucopurulent rhinosinitis
**Can cause pneumonia and mastitis in sheep
**Associated with [[Respiratory Bacterial Infections - Pathology#Pneumonic pasteurellosis|pneumonic pasteurellosis]] in cattle, as well as enzootic pneumonia in calves
*Type B
**Causes Haemorrhagic Septicaemia of cattle in Southern Europe and Asia
*Type D
**Primary and secondary pathogen
**Causes [[Respiratory Bacterial Infections - Pathology#In Pigs|atrophic rhinitis]] along with ''[[Bordetella bronchiseptica]]'' in pigs
**Pneumonia in pigs
**''Pasteurella multocida'' adhere to epithelium damaged by ''[[Bordetella bronchiseptica]]''
**Produces an osteolytic toxin (Pmt), which stimulates osteoclasts, inducing bone resorption of the nasal turbinates
*Type E
**Causes African Bovine Haemorrhagic Septicaemia[[Category:Pasteurella and Mannheimia species]]
