“…Although cockatoos appear to be readily susceptible to APV infection, disease in nestling and adult birds is extremely rare (Wainwright et al, 1987;Phalen et al, 1997). Mounting evidence suggests that these rare cases of APV-disease may only occur in cockatoos concurrently infected with and immunosuppressed by PsCV (Latimer et al, 1993(Latimer et al, , 1996D. N. Phalen, unpublished observation).…”

“…In domestically raised cockatoos, APV infection is common, yet APV disease is rare (Phalen et al, 1997). Increasing evidence suggests that APVdisease may only occur in cockatoos that are infected with both the psittacine circovirus (PsCV) and APV (Latimer et al, 1993(Latimer et al, , 1996; unpublished observation).…”

“…Co-infections of APV and psittacine beak and feather disease virus (PBFDV) have been revealed in China, Thailand, Poland, and other regions including Central America (Ramis et al 1998, Fungwitaya et al 2009, Piasecki and Wieliczko, 2010, Zhuang et al 2012, Dolz et al 2013. Concurrent APV and PBFDV infections have been reported in budgerigars, lovebirds, parrots, and several species of cockatoos (Latimer et al 1993).…”

ABSTRACT.A 6 week old Plum-headed parakeet (Psittacula cyanocephala) from a private bird collection in the Metropolitan Region of Chile died after presenting depression, ataxia, tremors of the head, subcutaneous hemorrhage and delayed crop emptying. Histological examination of liver tissue revealed intranuclear viral inclusion bodies and focal necrosis. Liver tissues and blood contained both avian polyomavirus (APV) and psittacine beak and feather disease (PBFD) viral nucleic acids (DNA), indicating dual viral infection. The purpose of this report is to describe the first case of concurrent psittacine beak and feather disease virus PBFDV and APV infection in a psittacine bird in captivity in Chile. PBFDV has not been reported until now in Chile.Key words: avian polyomavirus, psittacine beak and feather disease. RESUMEN.Una cotorra ciruela (Psittacula cyanocephala) de seis semanas de edad de una colección privada de aves en la Región Metropolitana de Chile, murió después de presentar depresión, ataxia, tremor de la cabeza, hemorragia subcutánea y enlentecimiento en el vaciamiento del buche. El examen histopatológico del tejido hepático reveló la presencia de cuerpos de inclusión intranucleares y necrosis focal. Hígado y sangre del ave contuvieron ácidos nucleicos virales de "avian polyomavirus" (APV) y "psittacine beak and feather disease virus" (PBFDV) indicando una infección viral dual. El propósito de esta comunicación es describir el primer caso de infección concurrente por APV y PBFDV en un ave psitácida en cautiverio en Chile. Hasta ahora, PBFDV no había sido reportado en Chile.Palabras clave: virus polioma aviar, enfermedad del pico y pluma de psitácidas.

“…The 4-/mi thick tissue sections were mounted on 3-aminopropyltriethoxylane-coated slides (Probe-On Plus slides, Fisher Scientific Inc, USA). A manual capillary-action work station (MicroProbe system, Biomeda Corp., Foster City, CA, USA) was used to facilitate the in situ technique which was performed following published guidelines with minor modifications (Garcia et al, 1993(Garcia et al, , 1994Latimer et al, 1993;Goodwin et al, 1996). Replicate tissue sections were placed in a rack, deparaffinized in a 3:1 solution of limolene: xylene and rehydrated by passage through graded alcohols to Automation buffer (Biomeda Corp., Foster City, CA, USA).…”

A dual natural infection with psittacine beak and feather disease virus and budgerigar fledgling disease virus in a breeding aviary of budgerigars (Melopsittacus undulatus) is described. One-hundred per cent of newly-hatched birds were affected and mortality was high (85%). Most surviving birds had diarrhoea, feather alterations and 30% mortality after a 5-to 10-week period. Necropsies of 1-week-old and 2-month-old birds demonstrated non-specific lesions, but histologically nuclear inclusions suggestive of viral infection (adenovirus, herpesvirus, polyomavirus) and also cytoplasmic inclusions suggestive of beak and feather disease were seen in integument and internal organs. Staining of tissues with viral specific DNA probes for psittacine beak and feather disease virus and for avian polyomavirus demonstrated simultaneous presence of viral DNA from both viruses in some birds. This is the first description of a concurrent outbreak of psittacine beak and feather disease virus and avian polyomavirus infection in a breeding aviary.
