Nipah virus causes periodic livestock and human disease with high case fatality rate, and consequent major economic, social and psychological impacts. Fruit bats of the genus Pteropus are the natural reservoir. In this study, we used real time PCR to screen the saliva and urine of P. vampyrus from North Sumatera for Nipah virus genome. A conventional reverse transcriptase (RT-PCR) assay was used on provisionally positive samples to corroborate findings. This is the first report of Nipah virus detection in P. vampyrus in Sumatera, Indonesia.

African swine fever (ASF) is a highly lethal and contagious viral haemorrhagic disease of domestic and wild pigs, caused by the ASF virus (ASFV). After entering China in 2018, the disease has continued to spread through Asia. In September 2019, a team from the Indonesian Research Center for Veterinary Science, Bogor, investigated outbreaks in backyard pigs in the Dairi and Humbang Hasundutan districts of North Sumatra province. In January 2020, three pigs purchased from a pig seller in Bogor District, West Java province were also tested. Real‐time PCR results confirmed ASFV DNA in sixteen out of twenty‐nine samples, with nine positive samples from North Sumatra and seven from West Java. Four partial or full‐length genes (i.e. p72, p54, pB602L and CD2v) and a 356‐bp fragment between the I73R and I329L genes were sequenced from representative samples. Phylogenetic analysis established that the ASFV in the samples from both North Sumatra and West Java were identical, indicating a common source of infection, and that they belonged to the p72 genotype II and serogroup 8. The sequences from the Indonesian ASFVs were also identical to other genotype II ASFV from domestic pigs in Vietnam, China and Russia.

<p class="00-6Abstrak2Wtz">African swine fever (ASF) is a highly infectious disease in pigs that caused by the double-stranded DNA virus of the Asfarviridae family. The disease is characterized by haemorrhages in the ears, back and legs. This virus causes death in pigs and has a large economic impact. However, ASF is not a zoonotic disease, hence it has no an impact on human health. This paper  will discuss about ASF disease, route of transmision, how to diagnose, and handling of ASF. This disease has spread throughout Asia in a relatively short time in 2019, and this exotic disease has been reported entering Indonesia at the end of 2019. There is no effective prevention and control of the disease. Several vaccines have been developed but are still considered ineffective while commercial vaccines are not yet available. Safety and effectiveness of vaccines are still being considered because ASF virus is very unique and different from other DNA viruses,. Therefore, prevention of ASF infection should be done by conducting strict biosecurity, applying regulations on the movement of pigs and pig products to the region or country.</p>

<p><em>Lumpy skin disease</em> (LSD) menyebabkan kerugian ekonomi bagi peternak sapi, yang disebabkan oleh  virus LSD, genus <em>Capripoxvirus</em>,  famili <em>Poxviridae</em>.  Penyakit ini di karakterisasi dengan adanya nodul pada kulit.  Virus ini hanya menginfeksi sapi dan kerbau rawa yang memiliki tingkat mortalitas rendah, namun tingkat morbiditas tinggi. Sedangkan virus ini tidak menginfeksi kambing dan domba. Hingga saat ini, LSD belum pernah dilaporkan di Indonesia, oleh karena itu pengenalan penyakit LSD diperlukan terutama bagi dokter hewan dan paramedis lapangan sehingga infeksi LSD dapat diketahui dan penanganannya dapat dilakukan  lebih dini. Tulisan ini akan membahas mengenai penyakit LSD, cara penyebaran penyakit, epidemiologi, diagnosis, faktor risiko  serta pengendalian penyakit LSD, sehingga diharapkan masuknya infeksi LSD dapat terdeteksi sedini mungkin  dan  diantisipasi dengan  lebih arif oleh pemangku kebijakan.</p><p> </p>
