Abstract
Lumpy Skin Disease (LSD) is a notifiable viral disease caused by Lumpy Skin Disease virus (LSDV). It is usually associated with high economic losses, including a loss of productivity, infertility, and death. LSDV shares genetic and antigenic similarities with Sheep pox virus (SPV) and Goat pox (GPV) virus. Hence, the LSDV traditional diagnostic tools faced many limitations regarding sensitivity, specificity, and cross-reactivity. Herein, we fabricated a paper-based turn-on fluorescent Molecularly Imprinted Polymer (MIP) sensor for the rapid detection of LSDV. The LSDV-MIPs sensor showed strong fluorescent intensity signal enhancement in response to the presence of the virus within minutes. Our sensor showed a limit of detection of 101 log10 TCID50/mL. Moreover, it showed significantly higher specificity to LSDV relative to other viruses, especially SPV. To our knowledge, this is the first record of a paper-based rapid detection test for LSDV depending on fluorescent turn-on behavior.

Abstract
In this study, in order to reveal the immune response against the disease in naturally infected sheep with SPPV, the expressions of various pro- or anti-inflammatory cytokines such as tumour necrosis factor alpha (TNF-α), interferon gamma (IFN-γ), interleukin-1beta (IL-1β), interleukin-2 (IL-2), interleukin-6 (IL-6), interleukin-8 (IL-8), interleukin-10 (IL-10) and interleukin-12 (IL-12) were evaluated immunohistochemically. The material of this study consisted of tissue samples taken from 24 sheep, which were brought as dead for routine histopathological examination to the Department of Pathology. Avidin-biotin-peroxidase method was used for immunohistochemistry. Characteristic pox lesions were observed in the skin, lungs and kidneys. In histopathological examinations, pox cells, which are very characteristic for the diagnosis of the disease, were observed in all three tissues. Capripoxvirus nucleic acid was detected in 8 of the 24 tissues. Samples were sequenced, and a phylogenetic tree was constructed with reference strains from GenBank. Strains from the study clustered with sheeppox virus references. In conclusion, the levels of pro-inflammatory cytokines such as TNF-α, IFN-γ, IL-1β, IL-2, IL-8 and IL12 (Th1) were much more dominant compared to the levels of anti-inflammatory cytokines: IL-10 and IL-6 (Th2). This supported the fact that the cellular immune response is much more effective than the humoral immune response in sheeppox.

Abstract
Lumpy skin disease (LSD) is a transboundary, systemic, viral disease of cattle. The first outbreaks of LSD were reported in Lang Son Province of Vietnam (bordered to China), and an official document has been submitted to OIE on 1 November 2020. Here, we described first the genetic profiles of this pathogen based on four well-known marker regions. The LSD virus isolated in these first outbreaks was 100% identical to viruses isolated in China (2019) based on the p32 and RP030 genes. Additionally, it is very close to the virus isolated in Russia (2017) based on the p32, RP030, thymidine kinase and ORF103 genes (100%, 99.01%, 99.08% and 99.47% identities). This finding is new, and a success in LSD virus isolation using MDBK cells from first outbreaks is important for vaccine development to control and eradicate LSD in Vietnam.

Molecular phylogeny of Capripoxviruses based on major immunodominant protein (P32) reveals circulation of host specific sheeppox and goatpox viruses in small ruminants of India. INFECTION GENETICS AND EVOLUTION 2020; 85:104472. [PMID: 32711078 DOI: 10.1016/j.meegid.2020.104472] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Subscribe] [Scholar Register] [Received: 05/26/2020] [Revised: 07/16/2020] [Accepted: 07/18/2020] [Indexed: 11/26/2022]
Abstract
Sheeppox and goatpox are highly contagious viral diseases of small ruminants causing severe economic losses to the livestock farmers. The disease is enzootic in Asia including India, Middle East and African countries. In the present study, a total of 28 isolates from twenty five sheeppox and goatpox disease outbreaks were phylogenetically analyzed based on P32 gene/protein along with homology modeling and docking using heparan sulfate and UDP-glucose. Three distinct lineage-specific clusters as per their host origin were recorded. Multiple sequence analysis of P32 gene revealed that genetically similar sheeppox virus (SPPV) and goatpox virus (GTPV) strains are circulating in India. Phylogenetically, Lumpy skin disease (LSDV) and SPPV had a closer genetic relationship than GTPV. Comparative sequence alignment indicated conservation of various motifs such as glycosaminoglycan (GAG), chemokine like motif (CX3C) and Asp-Glu-any other residue-Asp (D/ExD), as well as viral specific signature residues in SPPV and GTPV isolates. Structurally, P32 protein of SPPV and GTPV with mixed α helices and β sheets resembled with crystal structure of homologue vaccinia virus H3L protein. Docking studies in P32 protein of SPPV and GTPV revealed conserved binding pattern with heparan sulfate which is involved in the virus attachment and varied glycosyltransferase fold with UDP-glucose. These findings may help in development of suitable vaccines/diagnostics and therapeutics against capripoxviruses.

Abstract
Capripox viruses are the causative agents of important animal diseases in cattle (Lumpy Skin Disease), sheep (Sheeppox) and goats (Goatpox) with severe socio-economic impact in case of wide scale outbreaks. Therefore there is a constant need for adequate diagnostic tools. The assays must be fit-for-purpose to identify the virus quickly and correctly and to be useful for surveillance and monitoring at different stages of an epidemic. Different diagnostic performance characteristics are required depending on the situation and the test purpose. The need for high throughput, high specificity/sensitivity and the capability for differentiating field virus strains from vaccine strains drives the development of new and better assays preferably with an advantageous cost-benefit balance. This review aims to look at existing and new virological and serological diagnostic tools used in the control against diseases caused by Capripox viruses.

Abstract
BACKGROUND Sheeppox (SPP) is one of the priorities, high-impact animal diseases in many developing countries, where live attenuated vaccines are routinely used against sheeppox virus (SPPV). In an event of an SPP outbreak, historically disease-free countries would hesitate to use of live vaccines against SPPVdue to the safety and trade reasons. Currently no killed SPPV vaccines are commercially available. In this study, we developed an inactivated Romanian SPPVvaccine and assessed its efficacy and potency in comparison with a live attenuated Romanian SPPV vaccine. Four naïve sheep were vaccinated once with the Romanian SPPV live attenuated vaccine and16 sheep were vaccinated twice with the inactivated vaccine. All sheep in the live vaccine group were included in the challenge trial, which was conducted using a highly virulent Moroccan SPPV field strain. Eight sheep of the inactivated vaccine group were challenged and the remaining sheep were monitored for seroconversion. Experimental animals were closely monitored for the appearance of clinical signs, body temperature and inflammation at the injection site. Two naïve sheep were used as unvaccinated controls. RESULTS The inactivated Romanian SPPV vaccine was found to be safe and confer a good protection, similar to the live vaccine. Specific antibodies appeared from seven days post vaccination and remained up to nine months. CONCLUSION This study showed that the developed inactivated Romanian SPPV vaccine has a potential to replace attenuated vaccine to control and prevent sheep pox in disease-free or endemic countries.

Abstract
CONCLUSION The c.235delC of GJB2 gene is the hotspot mutation of the hearing loss population in the Silk Road region of China. It is high time that some active interventions (such as hearing aids or cochlear implant) are provided to improve their language ability and quality of life. OBJECTIVES The first gene to be identified for humans with nonsyndromic hearing loss was GJB2 gene. We investigated the prevalence of GJB2 mutations in the Silk Road region of China to study the mutation spectrum in this area. METHODS Bidirectional sequencing was carried out for all PCR products of samples. The statistical analysis was carried out using SAS 9.0.1 software. RESULTS Pathogenic mutations were identified in 243 of 2398 patients, including 168 homozygous mutations and 75 compound heterozygous mutations. Three variants (c.225G>T, c.521G>A, and c.557C>T) are novel mutations.
