Aims:
Psittacine birds such as parrots, macaws, cockatoos, lovebirds and parakeets, are widely reared as household
pets or at aviary due to their attractive features. However, the status of virus-causing diseases of psittacine species in
Malaysia is fairly under-documented. Therefore, this study was aimed to detect the presence of three common avian
viruses that infect psittacine birds, i.e. beak and feather disease virus (BFDV), avian polyomavirus and avian
papillomavirus.
Methodology and results:
Faecal samples from twelve asymptomatic captive psittacine birds of different species were
collected from an undisclosed animal garden in Serdang, Selangor, Malaysia. Briefly, the sample was homogenised and
resuspended with SM buffer with the ratio 1:1 (weight of sample/g: volume of SM buffer/mL) before centrifugation at
1,000 × g for 20 min. The supernatant was collected and filtered before subjected to genomic DNA extraction using a
commercialised kit. Polymerase chain reaction (PCR) technique was used to screen the V1, VP1 and L1 genes of beak
and feather disease virus (BFDV), avian polyomavirus and avian papillomavirus, respectively. Findings revealed that the
samples were negative for BFDV and avian polyomavirus. However, positive results of 1.5 kbp PCR amplicon were
detected for avian papillomavirus in four out of the 12 samples (33.33%), which was from the white-crested cockatoo,
African grey parrot, yellow-collared macaw and Senegal parrot. Sequence analysis of the L1 gene from the Senegal
parrot Poicephalus senegalus revealed 93% identity to a reference Psittacus erithacus timneh avian papillomavirus.
Conclusion, significance and impact of study
This study added to the limited prevalence data of three important
avian viruses which infect captive psittacines in Seri Kembangan, Selangor, Malaysia. Avian papillomavirus, but not
BFDV and avian polyomavirus, was detected in the collected captive psittacine birds. Therefore, a routine screening can
be performed to monitor the health status of birds despite their asymptomatic manifestation, in order to prevent possible
virus transmission.

Asian-lineage H5 highly pathogenic avian influenza (HPAI) viruses have caused continuous outbreaks in poultry and wild birds. Development of rapid and accurate diagnostic methods is needed for preventing further spread of the virus and reducing the time required for eradication of the virus. We developed a low-density microarray for the rapid detection and identification of avian influenza virus subtypes H5, H7, and H9 and their pathotypes in a previous study. In the present study, we evaluated previously developed diagnostic microarray using avian influenza viruses isolated in Mongolia, including H5 HPAI viruses. All H5 HPAI viruses isolated in Mongolia were shown as H5-specific and highly pathogenic pattern in the microarray. H2, H3 and H12 viruses isolated in Mongolia used in this study did not show any H5, H7 and H9 patterns. These results indicated that this diagnostic microarray has enormous potential for the rapid subtyping and pathotyping of influenza viruses, including viruses isolated in Mongolia.

Korea is located within the East Asian-Australian flyway of wild migratory birds during the fall and winter seasons. Consequently, the likelihood of introduction of numerous subtypes and pathotypes of the Avian influenza (AI) virus to Korea has been thought to be very high. In the current study, we surveyed wild bird feces for the presence of AI virus that had been introduced to Korea between September 2017 and February 2018. To identify and characterize the AI virus, we employed commonly used methods, namely, virus isolation (VI) via egg inoculation, real-time reverse transcription-polymerase chain reaction (rRT-PCR), conventional RT-PCR (cRT-PCR) and a newly developed next generation sequencing (NGS) approach. In this study, 124 out of 11,145 fresh samples of wild migratory birds tested were rRT-PCR positive; only 52.0% of VI positive samples were determined as positive by rRT-PCR from fecal supernatant. Fifty AI virus specimens were isolated from fresh fecal samples and typed. The cRT-PCR subtyping results mostly coincided with the NGS results, although NGS detected the presence of 11 HA genes and four NA genes that were not detected by cRT-PCR. NGS analysis confirmed that 12% of the identified viruses were mixed-subtypes which were not detected by cRT-PCR. Prevention of the occurrence of AI virus requires a workflow for rapid and accurate virus detection and verification. However, conventional methods of detection have some limitations. Therefore, different methods should be combined for optimal surveillance, and further studies are needed in aspect of the introduction and application of new methods such as NGS.
