Lumpy skin disease (LSD) is a severe disease of bovine characterized by nodules on the skin, mucous membranes, and profuse nasal discharge which causes severe economic losses. In October 2020, an LSD outbreak case was found in Inner Mongolia Autonomous Region, China. A total of 1,206 cattle were sold from the same imported animal quarantine field to 36 farms after the quarantine period finished, and over 30 farmers reported symptoms such as skin scabs found in newly arrived cattle shortly after that. A large-scale LSD outbreak investigation was launched after laboratory diagnosis confirmed LSD. The clinical samples of 1,206 cattle from 36 farms, including 1,206 whole blood, 1,206 oral and nose swabs, and 355 scabs, were collected for the qRT-PCR test. The result showed that 51 whole blood samples (4.23%), 580 swab samples (48.09%), and 350 skin scabs (98.59%) were lumpy skin disease virus (LSDV) positive, 33 of 36 farms were affected. This study aims to provide a basis for LSD epidemiological traceability, movement control, and measures for prevention and control.

The recent outbreak of lumpy skin disease virus (LSDV) in the wetland areas of Bangladesh presents a significant concern for both animal health and regional biosecurity. Epidemiological investigations into nine major outbreaks in the wetland areas revealed distinctive clinical symptoms in affected cattle, including elevated body temperature, excessive salivation, and the presence of skin nodules. Histopathological examination unveiled larger nodules compared to previous outbreaks, along with signs of secondary infection.

Capripoxviruses (CaPVs), such as lumpy skin disease, sheep pox, and goat pox, cause significant production and economic losses and are major constraints to the growth of livestock production in endemic areas. Understanding the pathogenic mechanism of CaPVs and their translation into clinical applications depends on the availability of a suitable cell line. In this study, we used a lentiviral packaging system to establish an immortalized hTERT-bOEC cell line by ectopic introduction of human telomerase reverse transcriptase (hTERT).

Lumpy skin disease (LSD) has emerged as a threat to cattle production in Asia, and India has been facing LSD epidemics since 2019. Although water buffalo (Bubalus bubalis) is susceptible to natural LSDV infection, there have been no confirmed reports of LSDV infection in water buffalo in India. In this study, we investigated suspected cases of LSD in water buffaloes from 12 Indian states and one union territory during 2020-2023.

Lumpy skin disease virus (LSDV), a member of the capripoxvirus genus, induces lumpy skin disease (LSD) in cattle and buffalo populations. The initial documentation of LSD dates back to 1929 in Zambia, with subsequent rapid dissemination within the cattle community in Africa and Asia. Described as the "smallpox" equivalent in cattle, LSD manifests through clinical features such as fever, extensive cutaneous nodules, body wasting, lymph node enlargement, and skin edema.
