A total of 744 Escherichia coli strains isolated from 830 fecal samples of healthy cattle and pigs in all provinces of Korea were examined for resistance to 16 antimicrobials. The most frequently observed resistance in cattle isolates was to tetracycline (30.5%), followed by resistance to streptomycin (20.4%), ampicillin (12.0%) and chlorampenicol (6.9%).(More)
The population structure of the Bacillus cereus group (52 strains of B. anthracis, B. cereus, and B. thuringiensis) was investigated by sequencing seven gene fragments (rpoB, gyrB, pycA, mdh, mbl, mutS, and plcR). Most of the strains were classifiable into two large subgroups in six housekeeping gene trees but not in the plcR tree. In addition, several(More)
Lactic acid bacteria originated from swine feces and intestines were selected for potential probiotics based on their bile-salt resistance, low pH tolerance, potential adhesion to epithelial cells and especially functional properties, including production of antimicrobial substances, bile-salt hydrolase (BSH) and amylolytic activity. Results showed 7(More)
Comparative sequence analysis was performed upon Bacillus anthracis and its closest relatives, B. cereus and B. thuringiensis. Portions of rpoB DNA from 10 strains of B. anthracis, 16 of B. cereus, 10 of B. thuringiensis, 1 of B. mycoides, and 1 of B. megaterium were amplified and sequenced. The determined rpoB sequences (318 bp) of the 10 B. anthracis(More)
The complete genome sequence of porcine enterovirus B (PEV-B) from a Korean isolate was analyzed. The genome size was 7,393 bp. Previously, full genome sequences of PEV-B had been reported from the United Kingdom, Hungary, and China. The Korean PEV-B isolate presented polyprotein gene nucleotide sequence similarities of 77.9, 73.7, 78.9, and 80.3%,(More)
The hepatitis C virus (HCV) genotype is the most important factor in predicting the outcome of chronic hepatitis C treatment. Therefore, convenient and accurate HCV genotyping methods for routine laboratory testing are needed. In this study, to identify the HCV genotypes, an oligonucleotide DNA chip was designed using 15 probes from the 5'-untranslated(More)
The mitochondrion is the organelle responsible for generation of most usable energy in a cell. It also plays an important role in a series of physiological processes such as apoptosis and proliferation. Although previous studies have demonstrated that nicotine modulates the morphology and function of mitochondria, the mechanism(s) underlying these effects(More)
PURPOSE The Japanese encephalitis virus (JEV) genotype circulating in Korea has changed from G3 to G1. Therefore, the purpose of this study was to compare the antigenic relationship between the two genotypes by using antibody tests. MATERIALS AND METHODS Blood samples from 42 sows and 216 horses were collected, and their seroprevalence was monitored using(More)
Gram-negative bacteria (GNB) with multidrug resistance pose a serious threat to public health. They are environmental pathogens frequently isolated from raw milk and mastitis in dairy cattle. This study was to examine the in vitro antimicrobial activities against 225 isolates belonging to six important species of GNB from mastitic raw milk samples of dairy(More)
OBJECTIVE Prostaglandin E2 (PGE2) has a wide range of regulatory action in diverse cell types. To investigate the role of PGE2 in rheumatoid arthritis (RA), we tested the effect of exogenous PGE2 on the production of cytokines in synoviocytes. METHODS Fibroblast-like synoviocytes (FLS) were prepared from the synovial tissue of patients with RA and(More)
