Psittacine Herpes Virus (PsHV)
Blood sample (in EDTA or just a drop on a sterile swab), chloacal swab, liver
Duration of the investigation:
One to two days after receiving the sample
Pacheco’s disease is caused by a herpes virus which only affects psittacine birds.
An infection of a livestock usually occurs by clinically healthy carriers (infected birds without any symptoms). Due to stress the virus can then be reactivated and the birds spread it via feces. The incubation period (the time elapsed between exposure to the pathogen and when symptoms are first apparent) is from 3 to 10 days.
Sick birds show common symptoms like apathy, absence of appetite and sometimes regurgitation. A typical sign of Pacheco’s Disease is yellow-green diarrhea. In the majority of cases the birds die within a few hours or days. Mostly sudden death is to be seen without any previous symptoms.
A confirmed diagnosis is possible by detecting the viral DNA from blood samples, cloacal swabs and liver. All birds newly integrated into the livestock should be tested for already existing infections.
