The bacterium has many strains and is the pathogen responsible for Actinobacillosis in pigs of all ages. It can also infect wild birds, domestic ruminants, dogs, cats and horses.
The organism can be found in the respiratory tract and tonsils of both infected and healthy pigs that act as carriers. Transmission is via the respiratory tract and piglets are usually infected early on in life.
Herds with a high health status are more at risk and outbreaks can be explosive.
Clinical Signs and Diagnosis
Affected piglets can develop septicaemia, multifocal infections, respiratory signs, and may die.
Diagnosis relies on the culture of sampled tissues to isolate the organism.
