| | + | |
| | + | ==Introduction== |
| | + | Porcine adenovirus causes [[Diarrhoea|diarrhoea]] and [[Alimentary System|gastrointestinal]] disease in piglets and also often being implicated in '''multifactorial [[Respiratory System|respiratory]]''' diseases. |
| | + | |
| | + | pADV-4 is thought to be the most pathogenic of the porcine [[Adenoviridae|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, anorexia''' |
| | + | |
| | + | '''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, dspnoea, 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<ref> Buller, C. R., Moxley, R. A. (1988) Natural infection of porcine ileal dome M cells with rotavirus and enteric adenovirus. Vet Path, 25(6):516-517; 9</ref>. |
| | + | |
| | + | '''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 testing|ELISA]].''' |
| | + | |
| | + | ==Treatment== |
| | + | '''None''' is usually necessary as disease is mild and/or transient. |
| | + | |
| | + | ==Control== |
| | + | '''None''' is usually practised although a study has demonstrated beneficial use of a vaccine<ref> Kadoi, K (1997) Beneficial use of inactivated porcine adenovirus vaccine and antibody response of young pigs. New Microbiol. 20:89-91</ref> |
