*Synonym: '''Shipping fever'''
*Caused by [[Mannheimia haemolytica|''Manheimia haemolytica'' biotype A serotype 1 (90%)]] and ''[[Pasteurella multocida]]''
*In young, growing cattle
*In clinically normal cattle ''Mann. haemolytica'' serotype 2 is present in low numbers, only in nasal cavity and tonsils
*Clinical signs: depression, anorexia, rapid shallow respiration, crusty nose with mucopurulent discharge, serous ocular discharge
*Acute [[Bronchi and Bronchioles Inflammatory - Pathology#Infectious causes of bronchitis or bronchiolitis|bronchopneumonia]] and may progress to [[Lungs Inflammatory - Pathology#Lobar pneumonia|lobar pneumonia]] with toxaemia
*Pathology
**Lobar, cranioventral exudative pneumonia with fibrin, [[Pleural Cavity & Membranes Inflammatory - Pathology|fibrinous pleuritis]], areas of coagulative necrosis
*Histology
**Large numbers of bacteria are usually associated with necrotic lesions
