*Aerosol transmission by close contact with clinically or subclinically affected animals
  −
*Severity depends on strain and host susceptibility
  −
*Slow spread of infection
  −
*50% morbidity; mortality rate high in severe outbreaks
  −
*Large colony type causes pleuropneumonia, mastitis, septicaemia and polyarthritis
  −
 
  −
*Clinical signs
  −
**Acute onset fever, anorexia, depression, lowered milk yield, hyperpnoea, coughing and a mucopurulent nasal discharge
  −
**Dyspnoea occurs with abducted elbows and extended necks and an expiratory grunt
  −
**Can be fatal within 1-3 weeks
  −
**Calves may suffer from [[Joints Inflammatory - Pathology#In Cattle|arthritis]], synovitis and endocarditis
  −
 
  −
*Gross pathology
  −
**Marbled appearance to lungs with consolidated grey and red lobules separated by emphysematous areas
  −
**Serofibrinous pleural fluid
  −
**Necrotic foci surrounded by fibrous capsules in chronic cases act as source of infection
  −
 
  −
*Diagnosis
  −
**Clinical signs and post-mortem appearance
  −
**PCR on pleural fluid, lung tissue, regional lymph nodes or bronchoalveolar lavage fluid
  −
**Fluorescent antibody test
  −
**Serological tests such as serum agglutination, haemagglutination, complement fixation, ELISA
  −
 
  −
*Treatment and control
  −
**Slaughter of affected cattle in counries where the disease is exotic
  −
**Movement restrictions, quaranteen and slaughter of carrier animals in endemic countries
  −
*''M. mycoides'' subsp. 'mycoides'' causes septicaemia, pleuropneumonia, arthritis and mastitis in goats
  −
**Vaccination in endemic regions
  −
*Caused by [[Mycoplasma mycoides subsp. mycoides|''Mycoplasma mycoides'']], small colony variant
  −
*Causes a fibrinonecrotic [[Pneumonia Overview#Infectious causes of pneumonia|pneumonia]] and [[Pleural Cavity & Membranes Inflammatory - Pathology|fibrinous pleuritis]]
  −
*Also affects caudodorsal areas
  −
*[[Bronchopneumonia|Bronchopneumonia]] -> [[Lobar Pneumonia|lobar pneumonia]] 
  −
*Sequestra are common
  −
*NB: similarity to pneumonic pasteurellosis but CBPP has more pronounced marbled effect
  −
*Interstitial septa are markedly widened by fibrinous exudate and the necrotic areas may have a fibrous capsule
  −
*Large colony variant will cause a similar disease in goats
