==In general==
 
 
 
*Main clinical expression is as secondary invaders of previously damaged lung tissue due to viral or parasitic involvement or environmental stress
 
*Some are initial pathogens in their own right while others can damage the tract allowing invasion by more pathogenic types

*Caused by [[Haemophilus pleuropneumonia|''Haemophilus (Actinobacillus) pleuropneumonia'']]
 
*Seen mainly between 6wks-6mths of age but will affect any age
 
*Highly pathogenic strains are capable of initiating disease on their own with high mortality in young pigs
 
*A fibrinonecrotic [[Bronchi and Bronchioles Inflammatory - Pathology#Infectious causes of bronchitis or bronchiolitis|broncho]][[Lungs Inflammatory - Pathology#Infectious causes of pneumonia|pneumonia]] with [[Pleural Cavity & Membranes Inflammatory - Pathology|pleurisy]]
 
*Foci of haemorrhagic consolidation or necrosis, mainly around major bronchi, tend to sequestrate
 
*Tending to spread throughout all lung lobes: therefore a cranioventral distribution may not be particularly evident
 
 
 
===Glasser's disease===
 
 
 
*Caused by ''[[Haemophilus parasuis]]''
 
*May cause suppurative [[Bronchi and Bronchioles Inflammatory - Pathology#Infectious causes of bronchitis or bronchiolitis|broncho]][[Lungs Inflammatory - Pathology#Infectious causes of pneumonia|pneumonia]] and [[Pleural Cavity & Membranes Inflammatory - Pathology|pleuritis]] (as part of polyserositis)
 
*Stress of mixing, weaning and adverse environmental conditions are predisposing to the disease
 
 
 
===Streptococcal pneumonia===
 
 
 
*Caused by ''[[Streptococcus suis]]'' type II
 
 
 
===Tuberculosis in pigs===
 
 
 
*Pigs are susceptible to the [[:Category:Mycobacterium species|''Mycobacterium'' spp.]] causing tuberculosis [[Respiratory Bacterial Infections - Pathology#Tuberculosis|in cattle]]
 
*Rarely extends to lungs after haematogenous spread from ingested bacteria causing tubercles with various degrees of calcification, encapsulation and caseation
 
 
 
==In Rabbits==
 
 
 
===Snuffles===
 
 
 
*Caused by [[Pasteurella multocida|''Pasteurella multocida'']], less commonly and/or ''[[Bordetella bronchiseptica]]''
