parrot bornavirus (pabv)-2 isolate causes different disease patterns in cockatiels than pabv-4.psittaciform 1 bornavirus (pabv) has already been shown to be the aetiologic agent of proventricular dilatation disease, a significant disease of birds. however, the pathogenesis of pabv infection has not yet been resolved and valid data regarding the pathogenicity of different pabv species are lacking. thus, the present study was aimed to characterize the influence of two different pabv species on the course of disease. eighteen cockatiels were inoculated intracerebrally (i.c.) or intravenously ...201627100150
investigation of different infection routes of parrot bornavirus in cockatiels.the aim of this study was to determine the natural infection route of parrot bornavirus (pabv), the causative agent of proventricular dilatation disease (pdd) in psittacines. for this purpose, nine cockatiels ( nymphicus hollandicus ) were inoculated orally, and nine cockatiels were inoculated intranasally, with a pabv-4 isolate. to compare the results of the trials, the same isolate and the same experimental design were used as in a previous study where infection was successful by intravenous a ...201728301249
