Objective: The resurgence of lumpy skin disease virus isolates of different genotypic natures abolishes the accuracy of assays that target either vaccine or field strain genome. The aim of the present study was to develop a universal real-time PCR assay using TaqMan chemistry to cover field, vaccine, and recombinant strains of lumpy skin disease virus isolates.
Results: The PCR assay was designed based on a LSDV044 target region that offers a unique identification locus to facilitate the sensitive and specific detection of all isolates known to date. The efficiency of amplification, determined over five orders of magnitude, was 93%, with the standard deviation remaining in the range of 0.11-0.23. Evaluation of the assay repeatability on three different days revealed that the inter-run variability ranged from 0.83 to 1.22 over five repetitions across three runs. This new screening assay is proposed as a fast, efficient, and sensitive tool that can be employed in the basic or applied surveillance studies regardless of the genotype. Moreover, the assay can be used for the routine laboratory testing of animal samples during eradication programs for lumpy skin disease.

The three members of the genus capripoxvirus (CaPV), lumpy skin disease virus (LSDV), sheeppox virus (SPPV), and goatpox virus (GTPV) have common hosts and areas of overlapping geographical distribution with Rift Valley fever virus (RVFV). Hence, to ensure more cost-effective disease surveillance we developed and evaluated a Luminex assay for the simultaneous detection of antibodies against CaPV and RVFV in domestic ruminants. In cattle, the assay had a sensitivity (Se) of 98.

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.
