Torque teno sus virus (TTSuV), infecting domestic swine and wild boar, is a non-enveloped virus with a circular, single-stranded DNA genome. which has been classified into the genera Iotatorquevirus (TTSuV1) and Kappatorquevirus (TTSuV2) of the family Anelloviridae. A molecular study was conducted to detect evidence of a phylogenic relationship between(More)

The major epitope region of the glycoprotein B (gB) gene of the porcine cytomegalovirus (PCMV), with a length of 270 bp, was cloned and expressed in Escherichia coli Rosetta (DE3). The major gB epitope was detected using an agar gel precipitation and Western blot analysis with the polyclonal antibodies specific for the major epitope. An indirect-blocking(More)
Porcine torovirus (PToV) was detected from intestinal samples of piglets with diarrhea from 20 farms in southwest China. The total prevalence of PToV was 45% (9 out of 20 farms); it was the first detection of PToV in China, and also the study analyzed the phylogenetic relationships between the Chinese PToV and PToV reference strains as well as other(More)
Porcine kobuvirus (PKoV) is a member of the Kobuvirus genus within the Picornaviridae family. PKoV is distributed worldwide with high prevalence in clinically healthy pigs and those with diarrhea. Fecal and intestinal samples (n = 163) from pig farms in Sichuan Province, China were obtained to determine the presence of PKoV using reverse transcription(More)
Porcine cytomegalovirus (PCMV) is an immunosuppressive virus that mainly inhibits the immune function of the macrophage and T-cell lymphatic systems, and has caused huge economic losses to the porcine breeding industry. Molecular epidemiological investigation of PCMV is important for prevention and treatment, and this study is the first such investigation(More)
Porcine torovirus (PToV) is a member of the genus Torovirus which is responsible for gastrointestinal disease in both human beings and animals with particular prevalence in youth. Torovirus infections are generally asymptomatic, however, their presence may worsen disease consequences in concurrent infections with other enteric pathogens. A total of 872(More)
Transmissible gastroenteritis virus (TGEV; Coronaviridae family) causes huge economic losses to the swine industry. MicroRNAs (miRNAs) play a regulatory role in viral infection and may be involved in the mammalian immune response. Here, we report a comprehensive analysis of host miRNA expression in TGEV-infected swine testis (ST) cells. Deep sequencing(More)
Porcine torovirus (PToV) is associated with swine gastroenteritis, but its pathogenesis is uncertain because there is limited information regarding PToV due to its difficulty to adapt in vitro. This study has developed a rapid one-step reverse transcription loop-mediated isothermal amplification (RT-LAMP) method for the detection of PToV. A set of four(More)
Porcine Torovirus (PToV) is widely distributed in the world with high prevalence rate in swinery. Due to the high detection rate in diarrhea pigs, PToV is thought to be a potential pathogen of swine diarrhea. In recent years, epidemic outbreaks of diarrhea with high morbidity and mortality in China have caused great economic losses. Intertypic recombination(More)
