No information is currently available on porcine reproductive and respiratory syndrome virus (PRRSV) infection in wild boars (Sus scrofa) in Korea. In this study, the status of PRRS in wild boars was investigated. Blood samples were collected from 267 wild boars from eight provinces in Korea. Four of the samples tested (1.5%) were positive for PRRSV… (More)
In March of 2014, a variant of novel porcine epidemic diarrhea virus (PEDV) was first identified in South Korea and found to be most closely related to the U.S. variant strain OH851. The complete genome of the KOR/KNU-1406/2014 strain was sequenced and analyzed to investigate the U.S.-strain-like variant circulating in South Korea.
We address the mechanism by which adult intestinal stem cells (ISCs) become localized to the base of each villus during embryonic development. We find that, early in gut development, proliferating progenitors expressing ISC markers are evenly distributed throughout the epithelium, in both the chick and mouse. However, as the villi form, the putative stem… (More)
In late 2013, outbreaks of porcine epidemic diarrhea virus (PEDV) infection recurred in South Korea. Genetic and phylogenetic analyses showed that isolates from the outbreaks were most closely related to emergent US strains of PEDV. These US strain-like PEDV variants are prevalent in South Korea and responsible for recent outbreaks in the country.
In April 2014, porcine deltacoronavirus (PDCoV) was first identified in feces from diarrheic piglets in South Korea and found to be closely related to other PDCoV strains. The complete genome of the Korean PDCoV strain, KOR/KNU14-04/2014, was sequenced and analyzed to characterize PDCoV circulating in South Korea.
Porcine epidemic diarrhea virus (PEDV) is a highly contagious enteric pathogen of swine. Acute PEDV outbreaks have continually emerged in most swine-producing Asian countries and, recently, in the United States, causing significant economic losses in the pig industry. The spike (S) protein of PEDV is a type 1 transmembrane envelope glycoprotein and consists… (More)
A novel cytopathogenic paramyxovirus was isolated from a lung sample from a piglet, using continuous porcine alveolar macrophage cells. Morphologic and genetic studies indicated that this porcine virus (pPIV5) belongs to the species Parainfluenza 5 in the family Paramyxoviridae. We attempted to determine the complete nucleotide sequence of the first Korean… (More)
Gait asymmetry caused by hemiparesis results in reduced gait efficiency and reduced activity levels. In this paper, a portable rehabilitation device is proposed that can serve as a tool in diagnosing gait abnormalities in individuals with stroke and has the capability of providing vibration feedback to help compensate for the asymmetric gait.… (More)
The high genetic diversity of porcine reproductive and respiratory syndrome virus (PRRSV) has been an obstacle to developing an effective vaccine for porcine reproductive and respiratory syndrome (PRRS). This study was performed to assess the degree of genetic diversity among PRRSVs from Korean pig farms where wasting and respiratory syndrome was observed… (More)
Pseudomonas putida strain SJ3, which possesses caprolactam-degrading ability, was isolated from dyeing industry wastewater in Daegu, Republic of Korea. Here, we describe the draft genome sequence and annotation of the strain. The 5,596,765-bp-long genome contains 4,293 protein-coding genes and 68 RNA genes with 61.70% G+C content.
