===''Actinobacillus equuli''===
*Commensal of the equine intestinal mucosa
*Infection at birth causes severe enteritis and septicaemia within 24 hours, known as sleepy foal disease
*In foals that survive neonatal infection the condition progresses to cause joint infections and purulent nephritis
*''A. equuli'' in [[Joints - inflammatory#In Horses|arthritis of horses]]
*Abortion in mares
*Septicaemia in piglets
*Arthritis and enteritis in pigs
*Enteritis in calves
*RTX group cytotoxin present
===''Actinobacillus suis''===
*Fatal septicaemia in piglets 1-8 weeks old
*Causes abscesses in joints and lungs of older pigs
*Carried in the nasopharynx of pigs and nose of horses
*Carriage may confer immunity to the more severe pleuropneumonia
*Septicaemia and pneumonia in foals
*Pneumonia in pigs and horses
===''Actinobacillus seminis''===
