Emergence of Lumpy Skin Disease Virus Infection in Yaks, Cattle-Yaks, and Cattle on the Qinghai–Xizang Plateau of China
Lumpy skin disease (LSD) is a viral disease caused by lumpy skin disease virus (LSDV), which mainly infects cattle and can cause huge economic losses. In May 2023, yaks, cattle-yaks, and cattle in Tibet (Xizang), China, developed fever, skin nodules, and severe discharges and were suspected to be cases of LSD. Samples from these animals were analyzed using molecular biology and serological methods. The RPO30, P32, and GPCR genes were amplified by PCR and sequenced, and the whole genome of the virus was determined using viral metagenomics technology. Sequencing results showed that it was indeed an LSDV infection, and enzyme-linked immunosorbent assay results confirmed the presence of LSDV antibodies. The whole genome phylogenetic tree shows that LSDV/CHINA/Tibet/2023 is different from the previous epidemic strains in China, but clusters with India 2022 strain. This is the first report of LSD in yaks, cattle-yaks, and cattle on the highest altitude plateau in the world.
期刊介绍：
Transboundary and Emerging Diseases brings together in one place the latest research on infectious diseases considered to hold the greatest economic threat to animals and humans worldwide. The journal provides a venue for global research on their diagnosis, prevention and management, and for papers on public health, pathogenesis, epidemiology, statistical modeling, diagnostics, biosecurity issues, genomics, vaccine development and rapid communication of new outbreaks. Papers should include timely research approaches using state-of-the-art technologies. The editors encourage papers adopting a science-based approach on socio-economic and environmental factors influencing the management of the bio-security threat posed by these diseases, including risk analysis and disease spread modeling. Preference will be given to communications focusing on novel science-based approaches to controlling transboundary and emerging diseases. The following topics are generally considered out-of-scope, but decisions are made on a case-by-case basis (for example, studies on cryptic wildlife populations, and those on potential species extinctions):
Pathogen discovery: a common pathogen newly recognised in a specific country, or a new pathogen or genetic sequence for which there is little context about — or insights regarding — its emergence or spread.
Prevalence estimation surveys and risk factor studies based on survey (rather than longitudinal) methodology, except when such studies are unique. Surveys of knowledge, attitudes and practices are within scope.
Diagnostic test development if not accompanied by robust sensitivity and specificity estimation from field studies.
Studies focused only on laboratory methods in which relevance to disease emergence and spread is not obvious or can not be inferred (“pure research” type studies).
Narrative literature reviews which do not generate new knowledge. Systematic and scoping reviews, and meta-analyses are within scope.
