Screening for Circovirus (PiCV), Herpesvirus (PiHV) and Adenovirus (FAdV)
Blood sample (in EDTA or just a drop on a sterile swab), chloacal swab, tissue
Duration of the investigation:
One to three days after receiving the sample
The Young Pigeon Disease Syndrome mostly affects livestocks of racing pigeons. The infectious agent is a circovirus which damages lymphoid tissue and suppresses the immune system, so that secondary bacterial (in particular E. coli) and fungal infections may occur. A causal involvement of Adenoviruses and/or Herpesviruses cannot be excluded.
Typically however only about 5% of the birds in a loft actually show symptoms, while the other 95% although infected with the virus do not develop clinical symptoms. Sick birds show typical signs like ruffled feathers, lethargy, weight loss, diarrhea and regurgitation. These birds mostly die within 3 to 7 days. In another form, sudden death can occur without being preceded by any perceptible signs of illness.
Mostly, the pathogens are transmitted by dust and contact between birds. An outbreak of the disease is promoted by stress factors such as heat, overcrowded lofts or young pigeon flights.
All birds newly integrated into the livestock should be tested for already existing infections.
