''Actinobacillus suis'' is a beta-haemolytic, Gram-negative bacterium of the Pasteurellaceae family. 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. Adult pigs may show signs relating to pneumonia, lethargy, anorexia, skin lesions similar to Erysipelas and sudden death. Diagnosis relies on the culture of sampled tissues to isolate the organism. Signs and necropsy findings may mimic diseases such as: Erysipelas, Glasser's Disease, ''Streptococcus suis'' and ''Actinobacillus pleuropneumoniae''. 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「Actinobacillus suis」の詳細全文を読む スポンサード リンク
