Also Known As: pADV 1-5 — pADV A-C
Introduction
Porcine adenovirus causes diarrhoea and gastrointestinal disease in piglets and is also often implicated in multifactorial respiratory diseases.
pADV-4 is thought to be the most pathogenic of the porcine adenoviruses.
Distribution
Worldwide
Transmission is faecal:oral
Signalment
pADV is only known to affect swine.
Clinical Signs
pADV is a low grade pathogen, associated with short duration mild clinical signs.
Diarrhoea, inappetance, dehydration and anorexia often present in various degrees of severity.
Dullness, depression, lethargy, listlessness and tremors may develop, often secondary to dehydration.
Reproductive disease may present as abortion and stillbirth pigs.
Respiratory disease, e.g. cough, dyspnoea, blue extremities etc. often develops when combined with other pathogens.
Subclinical and asymptomatic infections are common.
Diagnosis
Histologically, pADV causes formation of nuclear inclusion bodies in the intestinal cells[1].
Viral isolation can be performed in tissue cultures. Cells infected become rounded and enlarged and then detach from the vessel.
Viral particles can be seen via electron microscopy up to 6 days post infection.
Immunoperoxidase and immunofluorescent staining can demonstrate viral antigen.
Antibodies can be detected serologically with immunodiffusion, complement fixation, serum neutralisation and ELISA.
Treatment
None is usually necessary as disease is mild and/or transient.
Affected animals can become dehydrated and so symptomatic treatment with fluid replacement solutions is recommended.
Control
None is usually practised although a study has demonstrated beneficial use of a vaccine[2]
