Ef. Kaleta et Mb. Brinkmann, AN OUTBREAK OF PACHECOS PARROT DISEASE IN A PSITTACINE BIRD COLLECTION AND AN ATTEMPT TO CONTROL IT BY VACCINATION, Avian pathology, 22(4), 1993, pp. 785-789
An outbreak of Pacheco's parrot disease (PPD) is described in a psitta
cine bird collection of a municipal ornithological garden. A herpes vi
rus was isolated and judged to be the causative agent from the mortali
ty recorded. A formaldehyde/heat-inactivated experimental vaccine was
prepared from polyethyleneglycol purified virus. The vaccine was local
ly and systemically well tolerated by all birds. Seroconversion was de
monstrated by neutralization tests in most of the vaccinated birds of
the genera Ara, Anodorhynchus and Probosciger.
