AbstractIntroductionAvian polyomavirus (APV) and psittacine beak and feather disease virus (PBFDV) induce contagious and persistent diseases that affect the beaks, feathers, and immune systems of companion birds. APV causes hepatitis, ascites, hydropericardium, depression, feather disorders, abdominal distension, and potentially death. PBFDV can induce progressive beak deformity, feather dystrophy, and plumage loss. We conducted the first prevalence survey of both APV and PBFDV infections in companion birds in eastern Turkey.Material and MethodsA total of 113 fresh dropping samples from apparently healthy companion birds were collected in a random selection. The dropping samples were analysed for PBFDV and APV by PCR. Positive samples were sequenced with the Sanger method. The sequence was confirmed through alignment and the phylogenetic tree generated through the maximum likelihood method computationally.ResultsPBFDV and APV were detected in a respective 48.7% and 23.0% of samples. Coinfection was found in 12.4% of the samples, these all being from budgerigars (Melopsittacus undulatus). APV and PBFDV were detected in budgerigar and cockatiel (Nymphicus hollandicus) samples.ConclusionThis report provides a foundation for future studies on the influence of these viruses on the health of companion birds. These high positive rates for both pathogens emphasise that healthy M. undulatus and N. hollandicus in eastern Turkey may be prone to the emergence and spread of APV and PBFDV with subclinical potential.

Nestling Mortality

High mortality of nestling cockatiels (<i>Nymphicus hollandicus</i>) was observed in one breeding flock in Slovakia. The nestling mortality affected 50% of all breeding pairs. In general, all the nestlings in affected nests died. Death occurred suddenly in 4- to 6-day-old birds, most of which had full crops. No feather disorders were diagnosed in this flock. Two dead nestlings were tested by nested PCR for the presence of avian polyomavirus (APV) and <i>Chlamydophila psittaci</i> and by single-round PCR for the presence of beak and feather disease virus (BFDV). After the breeding season ended, a breeding pair of cockatiels together with their young one and a fledgling budgerigar (<i>Melopsittacus undulatus</i>) were examined. No clinical alterations were observed in these birds. Haemorrhages in the proventriculus and irregular foci of yellow liver discoloration were found during necropsy in the young cockatiel and the fledgling budgerigar. Microscopy revealed liver necroses and acute haemolysis in the young cockatiel and confluent liver necroses and heart and kidney haemorrhages in the budgerigar. Two dead cockatiel nestlings, the young cockatiel and the fledgling budgerigar were tested positive for APV, while the cockatiel adults were negative. The presence of BFDV or <i>Chlamydophila psittaci</i> DNA was detected in none of the birds. The specificity of PCR was confirmed by the sequencing of PCR products amplified from the samples from the young cockatiel and the fledgling budgerigar. The sequences showed 99.6&minus;100% homology with the previously reported sequences. To our knowledge, this is the first report of APV infection which caused a fatal disease in parent-raised cockatiel nestlings and merely subclinical infection in budgerigar nestlings.
