Comparative studies on lumpy skin disease virus in human

Background: Lumpy Skin Disease Virus (LSDV), capripoxvirus, family poxviridae, was recently (2018-2019-till present) exhibiting its characteristic zoonosis [animal to human].Moreover, the person-to-person direct transmission [infectious disease] were recorded. Materials and Methods:Whole blood and tissue samples from skin nodules were collected from infected persons (showing characteristic pox nodules).LSDV was isolated on BHK-21 cell culture, and pathogen free embryonated chicken eggs (CAM).Diagnosis were confirmed by conventional Polymerase Chain Reaction and partial sequencing using the primers target gene ORF103 and Negative staining, direct electron microscopic examination.Results: LSDVh was successfully isolated from blood and skin nodules collected from infected persons.Confirmed diagnosis was achieved by the conventional PCR and sequencing procedures.The isolates were genetically characterized as Lumpy skin disease virus isolate Evros/GR/15 by partial sequence with 99 % identity.Meanwhile, LSDV virions and herpes virus particles were visualized by electron microscopic investigations (NS-DEM).The majority of LSD virions were nonenveloped showing Mulberry forms and some capsular form, and the enveloped forms.Herpes virus virions were also detected in large number, the enveloped and the non-enveloped.The apparent pathogenesis on infected human are comparatively similar to LSD in cattle however the progress of illness and stages of the disease depends on level of health care interventions.Unless the nature of human biology is greatly different from that of cattle.Conclusions: Lumpy skin disease virus is capable of infecting humans with direct transmission without the need for insects vector; that most probably by inhalation and certainly by the direct contacts with infected materials, infected persons [man to man], and as laboratory acquired infection.LSDVh causes skin nodules and may lead to death in cases of generalized infections and if involving the internal organs.However, it is obvious that Herpes virus gives hands and helping poxviruses during their pathogenesis in the infected subjects.
