- Peritonitis in sheep
- Permeability types of pulmonary oedema.
- Can be secondary to IBR
- Causes 'Snuffles' in rabbits
- Manheimia haemolytica biotype A serotype 1 (90%) and Pasteurella multocida cause pneumonic pasteurellosis
- Pasteurellosis in pigs
- Can cause vascular fragility, leading to haemorrhagic disease.
- M. haemolytica and P. multocida may contribute to Enzootic pneumonia of calves
- Often follows parainfluenza - 3 infection of cattle

- In pyothorax
- P. multocida in cellulitis in cats
Overview Pasteurella
- Found in the upper respiratory tract and gastrointestinal tract mucosa
- Usually opportunistic organisms, causing disease during times of stress, low resistance or concurrent infections
- Resist phagocytosis by their capsule
- Not part of the human bacterial flora
Bacteria Properties
- Short Gram-negative bacilli
- Oxidase-positive
- May show bipolar staining
- Catarrhal odour
- Produce endotoxins which cause host damage and death
Pasteurella multocida
- ===Typa A===
- Commensal in upper respiratory tract of animals in UK
- Commomly repsonsible for dog and cat bite wound infections in humans and animals
- Some strains involved in Atropic Rhinitis, and produce osteolytic toxin
- ===Type B===
- Causes Haemorrhagic Septicaemia of cattle in Southern Europe and Asia
- ===Type D===
- Causes Atropic Rhinitis along with Bordetella bronchiseptica
- Produces an osteolytic toxin, which stimulates osteoclast, inducing bone resorption
- ===Type E===
- Causes Afican Bovine Haemorrhagic Septicaemia
Pasteurella pneumotropica
- Carried in nasopharynx of many small rodents
- Causes pneumonia in rodents as a secondary disease
