Pigeon Adenovirus testing

Pathogen overview

The main cause of "adenovirus disease" (vomiting, diarrhoea, watery droppings), especially after basketing and transport stress. A major threat to race form.

Transmission

Spread by the faecal-oral route through contaminated feed and drinking water and through contact with the droppings of affected birds; stress such as basketing and transport is an important trigger.

Main impact

Causes severe vomiting, throwing of feed and watery diarrhoea, leading to rapid dehydration and sharp weight loss and, in severe cases, death; it is one of the main diseases that cause a major drop in performance during the racing season.

Why testing matters

Rapidly confirms adenovirus infection and differentiates it from other causes of diarrhoea such as Newcastle disease and rotavirus, guides fluid therapy and supportive care, and shortens the time out of competition.

Common symptoms

• ◆ Vomiting, throwing feed
• ◆ Watery diarrhoea, green droppings
• ◆ Complete loss of appetite
• ◆ Sharp weight loss

Differential diagnosis

Must be differentiated from other diarrhoea-causing pathogens such as Newcastle disease and rotavirus; adenovirus typically causes vomiting and watery diarrhoea after basketing stress.

Incubation period

Incubation period is short, often 1–3 days; outbreaks are common after stress such as basketing and transport, and spread is rapid.

Diagnostic methods

Collect cloacal swabs or faeces for qPCR detection of adenovirus nucleic acid for confirmation, interpreted together with the typical vomiting and diarrhoea.

Management and treatment

Treatment is mainly supportive — fluid therapy, control of diarrhoea and control of secondary infection; stress should be minimised during the racing season, and medication must follow veterinary guidance.

Prevention

Reduce transport and basketing stress, strengthen nutrition and immune support, and isolate affected birds promptly.
