Newcastle disease (ND) is a contagious disease in poultry and numerous birds of various ages. Eagle is considered a potential reservoir for ND transmission as a wild bird. This research was conducted to molecularly characterize Newcastle disease virus (NDV) isolated from ND cases in Brontok Eagle and analyze the pathogenesis in chicken embryos. qRT-PCR was conducted as conﬁrmation of NDV without mixing Avian Inﬂuenza (AI). Sequencing the fusion (F) and haemagglutinin-neuraminidase (HN) genes from the three NDVs was performed with a speciﬁc primer. Amino acid sequence compared with other NDV from Genbank. Pathogenicity, genetic variation, distance, and phylogenetic studies were analyzed using bioinformatics software (MEGA-X). This study analyzed pathogenesis based on lesions and distribution of viral antigens in chicken embryos infected with NDV. Observations were based on tissue lesions with HE and IHC staining. NDV isolated from three Brontok Eagles is classiﬁed as velogenic strain, virulent NDV (KRQKRF), and belonging to Genotype VII subgenotype VII.2. The NDV was detected in various organ lesions, more severe in the pulmo, trachea, proventriculus, and intestine of chicken embryos. That is still similar to the previous case reports in the ﬁeld. These results show that NDV, which infected Brontok Eagle, has similar molecular characteristics and pathogenesis in chickens. These cases could be a threat to the poultry industry. Further research, surveillance, and monitoring of wild birds are needed to obtain more NDV epidemiological information in wild birds.

Introduction: Newcastle Disease (ND) is an infectious disease in various types of poultry caused by the Newcastle Disease Virus (NDV). Cases of ND in Indonesia have been reported in commercial and backyard chickens, pigeons, ducks and geese, even in eagles and peacocks. Peacock is a wild bird protected by Indonesia's Government Regulation No. 7 of 1999. This study aims to identify, isolate and characterize the NDV molecularly in cases diagnosed as ND in peacocks. Method: Samples were obtained from organs (lungs and spleen) of peacocks which showed neurological symptoms, diarrhoea and then died. Real-time RT-PCR ND was used to identify the cause of death of the peacock. Virus isolation and observation of embryonic changes and death were carried out on embryonic chicken eggs. Sequencing was carried out to characterize the F and HN entire genes of the NDV. The nucleotide sequences were analyzed using MEGA-X software, including amino acid prediction, analysis of genetic variation at the amino acid level, homology and construction of the phylogenic tree. Result: The results of the sample identification were positive for the Newcastle disease virus. Observations of chicken embryos are stunted, have few feathers, are haemorrhagic, and die in less than 60 hours. Virus isolation was obtained with a titer of 26. Molecular analysis showed that the RRQKRF cleavage site pattern in the F gene had homology of 95.8-97.6% and was in the same branching area as the previous ND virus in Indonesia. There were no amino acid mutations at the antigenic site, glycolysis and neutralization epitopes in the HN gene. Conclusion: The virus isolated from the peacock is a velogenic strain of NDV, subgenotype VII.2 and has a close genetic range to the NDV that has been previously reported in commercial and domestic poultry. This result shows that ND is also a threat to protected wild birds.

Penelitian ini bertujuan mengarakterisasi marmut sebagai hewan model untuk penyakit Alzheimer dengan mengamati histopatologis otak dan aktivitas seluler glial fibrillary acidic protein (GFAP) pada otak yang diakibatkan oleh deplesi hormon testosteron. Dua belas marmut dibagi dua kelompok berdasarkan umur, yaitu enam marmut umur 16-32 bulan dan enam marmut umur 32-48 bulan. Deplesi testosteron dilakukan dengan cara kastrasi. Dua marmut dari setiap kelompok dinekropsi untuk koleksi sampel otak pada waktu satu, tiga, dan lima bulan setelah kastrasi. Bagian otak yang diambil adalah korteks, lobus parietalis, temporalis, dan hipokampus. Sampel otak dilakukan evaluasi patologis dengan pewarnaan hematoksilin dan eosin dan immunohistokimia dengan antibodi GFAP. Hasil penelitian menunjukkan bahwa deplesi testosteron dapat menyebabkan kerusakan otak yang ditandai oleh kematian sel neuron, peningkatan aktivitas sel-sel glia dan ekspresi GFAP pada jaringan otak.Kesimpulan penelitian adalah penurunan kadar testosteron dalam plasma darah menyebabkan terjadinya kematian sel neuron dan peningkatan aktivitas sel-sel glia pada otak.

Universitas Gadjah Mada (UGM) Real Work Lecture (KKN) is a student service program to make a real contribution to society by applying the knowledge and skills they have. One of the problems faced is a decrease in the potential of tourism pilot areas due to the pandemic, namely the Das Miring tourism pilot in Kromodangsan, Lumbungrejo, Tempel. In order to overcome this problem, the UGM DPKM sent KKN PPM students to the area in the hope that they could find a solution and revive the Das Miring tourist destination armed with the knowledge they had gained during their studies. This research uses a qualitative method with a descriptive approach. The unit of analysis in this research is UGM KKN PPM Period 2 students in Kromodangsan, Lumbungrejo, Kapanewon Tempel, Sleman Regency. The data collection process was carried out through participatory observation and documentation. The results of this research show that the presence of students to carry out KKN in the area has made a significant contribution in developing the tourism potential of Das Miring. Students have made various efforts, including revitalization, development and promotion of the Das Miring tourist destination. In conclusion, this KKN program has succeeded in driving positive initiatives in supporting the recovery and development of neglected tourist destinations, proving the important role of students in providing concrete benefits to society.
