An outbreak of diarrhea in pigs started in Guangdong, South China in January 2011. Cases were characterized by watery diarrhea, dehydration and vomiting, with 80–100% morbidity and 50–90% mortality in suckling piglets. The causative agent of the diarrhea was ultimately identified as porcine epidemic diarrhea virus (PEDV). In this study, we isolated a PEDV… (More)
Since October 2010, an outbreak of porcine epidemic diarrhea (PED) has been observed in some provinces of China. Here we report the complete genome sequence of porcine epidemic diarrhea virus (PEDV) strain LC, which was recently isolated from sucking piglets that suffered from severe watery diarrhea in Guangdong. It will help in understanding the… (More)
Five of 21 different Newcastle disease virus (NDV) strains isolated from China in 2007 gave false-negative results when detected with a previously reported loop-mediated isothermal amplification (LAMP) method, and mismatches were found between the target gene and LAMP primers. Therefore, an improved, sensitive, specific, and accelerated one-step reverse… (More)
A 5' conjugated minor groove binder (MGB) probe real-time PCR assay was developed in this study for porcine sapelovirus (PSV) detection and quantitation. Two primers and a MGB probe for the 5' untranslated region (UTR) gene were designed. The assay was capable of detecting about 103copies/μl of standard template per reaction. Moreover, it does not detect… (More)
Sapelovirus is a member of the family Picornaviridae and is emerging as an enteric porcine, simian, and avian pathogen. Here, we report the genome sequence of a novel porcine sapelovirus strain YC2011 isolated from piglets with severe diarrhea. The availability of the genome sequence is helpful to further investigations of molecular characteristics and… (More)
A porcine reproductive and respiratory syndrome virus (PRRSV) QY1 was serially passed on Marc-145 cells. Virulence of different intermediate derivatives of QY1 (P5, P60, P80, and P100) were determined. The study found that QY1 had been gradually attenuated during the in vitro process. Pathogenicity study showed that pigs inoculated with QY1 P100 and P80 did… (More)
Physical-layer Network Coding (PNC) can significantly improve the throughput of two-way relay channels. An interesting variant of PNC is Analog Network Coding (ANC). Almost all ANC schemes proposed to date, however, operate in a symbol by symbol manner (memoryless) and cannot exploit the redundant information in channel-coded packets to enhance performance.… (More)
A reverse transcription loop-mediated isothermal amplification (RT-LAMP) assay was developed for the rapid identification of Infectious bursal disease virus (IBDV). The RT-LAMP assay used a set of 4 primers to amplify the viral protein 2 gene of IBDV for the detection of IBDV, showing not only high efficiency but also analytic specificity. The data… (More)
Porcine orthoreoviruses belong to the family Reoviridae and cause mainly mild enteritis in piglets. We present here the complete genome sequence of a novel porcine orthoreovirus strain (GD-1) isolated from a piglet in southern China. Our data will facilitate future investigations of the molecular characteristics and epidemiology of porcine orthoreoviruses.
QY2010 is a highly pathogenic North American-type porcine reproductive and respiratory syndrome virus (PRRSV). The complete genome sequence shows that QY2010 shares low sequence identity (60 to 88.7%) to all known PRRSV isolates. Phylogenetic analyses further reveal that QY2010 constitutes a novel subgroup within the North American genotype of PRRSV.
