Porcine adenovirus (aka pADV 1-5 or pADV A-C) is a virus in the family Adenoviridae. It causes mild gastrointestinal diseases in pigs and is thought to contribute to multifactorial porcine respiratory diseases complexes.[1] Several strains of the virus can be found worldwide, and transmission occurs horizontally by the fecal-oral route.
Infection is often subclinical, and when clinical signs are seen they are mild and short-lived.[citation needed]
Gastrointestinal signs such as diarrhoea, anorexia and dehydration are most commonly seen in piglets. Reproductive signs such as abortion can be seen in adult sows.[citation needed]
Respiratory signs such as coughing can be seen if the infection is part of a multifactorial respiratory disease complex.[citation needed]
Histology, virus isolation, electron microscopy, immunoperoxidase and immunofluorescent staining, immunodiffusion, complement fixation, virus neutralisation and ELISA can all be used to confirm diagnosis.[citation needed]
Generally no treatment is required.[citation needed]
