A novel triplex real-time PCR assay for the differentiation of lumpy skin disease virus, goatpox virus, and sheeppox virus.

Introduction: Three members of (CaPV) genus, including lumpy skin disease virus (LSDV), goatpox virus (GTPV), and sheeppox virus (SPPV), are mentioned as notifiable forms by World Organization for Animal Health. These viruses have negatively impacted ruminant farming industry worldwide, causing great economic losses. Although SPPV and GTPV cause more severe clinical disease in only one animal species, they can transfer between sheep and goats.

Summary of the Current Status of African Swine Fever Vaccine Development in China.

African swine fever (ASF) is a highly lethal and contagious disease of domestic pigs and wild boars. There is still no credible commercially available vaccine. The only existing one, issued in Vietnam, is actually used in limited quantities in limited areas, for large-scale clinical evaluation.

A systematic review of genotypes and serogroups of African swine fever virus.

African swine fever virus (ASFV) is the causative agent of African swine fever (ASF). The virus causes an acute highly hemorrhagic disease in domestic pigs, with high mortality. Although the overall genome mutation rate of ASFV, a large DNA virus, is relatively low, ASFV exhibits genetic and antigenic diversity.

Genome comparison of African swine fever virus China/2018/AnhuiXCGQ strain and related European p72 Genotype II strains.

African swine fever was introduced into China in August 2018 and led to high mortality in domestic pigs. We reported the genome characterization of the China/2018/AnhuiXCGQ strain mainly based on next-generation sequencing and comparison with related European p72 Genotype II strains. The genome was 189,393 bp long, encoding 181 open reading frames.

Immunoproteomic analysis of Brucella melitensis and identification of a new immunogenic candidate protein for the development of brucellosis subunit vaccine.

In order to screen immunogenic candidate antigens for the development of a brucellosis subunit vaccine, an immunoproteomic assay was used to identify immunogenic proteins from Brucella melitensis 16 M soluble proteins. In this study, a total of 56 immunodominant proteins were identified from the two-dimensional electrophoresis immunoblot profiles by liquid chromatography tandem mass spectrometry (LC-MS/MS). Two proteins of interest, riboflavin synthase alpha chain (RS-α) and Loraine synthase (LS-2), which are both involved in riboflavin synthesis, were detected by two-dimensional immunoblots using antisera obtained from Brucella-infected human and goats.

Seroprevalence of Brucella infection in yaks (Bos grunniens) on the Qinghai-Tibet plateau of China.

The seroprevalence of Brucella infection in yaks was surveyed on the Qinghai-Tibet plateau of China in 2010. A total of 621 serum samples was collected from six counties and were tested by serum agglutination test. The results showed that 56 (9%) of the samples were positive for Brucella.

[Bone marrow mesenchymal stem cell transplantation aggravates postangioplasty aortic restenosis in rats].

Objective: To observe the effect of bone marrow mesenchymal stem cell transplantation on postangioplasty aortic restenosis in rats.

Methods: 48 SD rats were randomly divided into normal control group, balloon injury group, balloon injury and MSCs transplantation group. MSCs were pre-labeled by DAPI (25 microg/ml) and then infused into aorta through the balloon catheter (MSCs 2 x 10(6)/animal).
