|a1= ''A. suis'' is a beta-haemolytic Gram-negative bacterium.

|q3=How do the strains of ''A. suis'' differ?
 +
|a3=
 +
Strains have differences in their:
 +
*Lipopolysaccharides (LPS) known as 'O' antigens - variants O1, O2 and O3.
 +
*Capsules (CPS) refered to as 'K' antigen - variants K1, K2 and K3.
 +
|l3=Actinobacillus suis#Introduction
 +
|q4=Which strains are most commonly isolated from clinical cases?
 +
|a4=
 +
*O1/K1
 +
*O2/K3
 +
|l4=Actinobacillus suis#Introduction
 +
|q5=Which strain is the most virulent?
 +
|a5= O2/K2
 +
|l5=Actinobacillus suis#Introduction
 +
|q6=What species does ''A. suis'' mainly casue disease in?
 +
|a6=
 +
*Pigs (majority)
 +
*Neonatal calfs
 +
*Waterfowl
 +
*Alpacas
 +
*Horses
 +
|l6=Actinobacillus suis#Introduction
 +
|q7=What toxins do ''A. suis'' encode for?
 +
|a7= Similar toxins to apxI and apxII of ''A. pleuropneumoniae'', but they are less virulent. Once an animal is infected with A. suis it can provide partial cross protection against ''A. pleuropneumoniae''.
 +
|l7=Actinobacillus suis#Introduction
 +
|q8=What are the wild hosts for ''A. suis''?
 +
|a8=
 +
*Anatidae (ducks, geese and swans)
 +
*Coypu
 +
A. suis can also affect domestic species including cattle, sheep, goats, alpacas, zebu, dogs, cats and tenuous links to equine disease have been recorded (''A. suis''-like microorganism rather than ''A. suis'' itself).

|a9=

*Actinobacillosis in pigs
 +
*Pneumonia and localised infections in neonatal calves
 +
*Airsaculitis in waterfowl
 +
*Polyarthritis in alpacas
 +
*Septicaemia, acute haemorrhagic pulmonary infarction and necrotizing pneumonia in horses (tenuous link)
 +
|l9=Actinobacillus suis#Clinical signs
 +
|q10=What is the epidemiology of ''A. suis''?
 +
|a10=
 +
*Spread via aerososl infection and invasion of the upper respiratory tract
 +
*Haematogenously spread via infected emboli, adhering to the endothelium of blood vessels or becoming trapped in smaller vessels
 +
*Colonise piglets in the first three weeks of life - not all become infected, some may be carriers
