Inactivation of Lumpy Skin Disease Virus Isolate Obtained from the Field Outbreaks using Binary Ethylenimine

Present study was aimed to isolate and inactivate the lumpy skin disease virus from the field outbreaks, clinically suspected samples like skin lesions, skin scabs, skin nodules and blood were collected from the affected bovine species. The samples were homogenised and processed, DNA was isolated and they were initially amplified for Capripoxvirus specific partial P32 gene, followed by LSDV-specific EEV glycoprotein gene-LSDV126 using respective forward and reverse primers. The PCR positive samples are subjected for isolation and propagation MDBK cells. Once the CPE was noticed in infected flasks, the cells were lysed by three cycles of freeze and thaw, the culture fluid was collected and stored at -20°C. The infected cell culture fluid was subjected for molecular detection by conventional PCR by primers targeting LSDV126 gene which is specific for LSDV. After molecular confirmation the viral isolates were assayed for titres and the infectivity titre was calculated by Reed and Muench (1938) and subjected for inactivation using BEI.
