Abstract


Numerous of Cases of skin nodules eruptions tied to lumpy skin disease virus (LSDV) are becoming more frequent in Qailubia Province, Egypt amongst cattle populations in 2014. In this study, a strain of LSDV (LSDV-Elkady-2014) associated with that outbreak was isolated from scabs of clinically infected Frisian cattle on chorioallantoic membrane (CAM) of specific pathogen free embryonated chicken eggs (SPF-ECEs). The isolate induced hemorrhage, enlarged liver, slight heart hypertrophy of chick embryos, with a pock lesion on CAM. Identification of LSDV-Elkady-2014 isolate was confirmed by histopathology, electron microscopy (EM), immunoflourescence (IF), and polymerase chain reaction (PCR) targeting LSDV envelope protein-like gene. Based on the partial sequence analysis of LSDV envelope protein-like gene. LSDV strain was phylogenetically related to LSDV- NI-2490, LSDV/ NW/LW, and LSDV/2/slemani/Kurdistan/ 2014. In conclusion, LSDV is still circulated in Egypt, and the isolated strain induced characteristic properties on chick embryos that were not previously recorded by LSDV.
