Varicella-zoster virus (VZV) causes chickenpox in children and shingles in older people. Currently, live attenuated vaccines based on the Oka strain are available worldwide. In Korea, an attenuated VZV vaccine has been developed from a Korean isolate and has been commercially available since 1994. Despite this long history of use, the mechanism for the(More)
Human cytomegalovirus (HCMV) is a ubiquitous human pathogen and contains double stranded DNA genome with approximately 230 kbp. Because of its huge size, comparative genomic studies of HCMV genome have been limited. In this study it was attempted to obtain and analyze the full genome sequence from clinical isolate from Korea. The strain JHC was isolated(More)
INTRODUCTION The National Polyp Study demonstrated that removal of adenomas with at least a three-year follow up reduced the incidence of colorectal cancer. However, compliance with follow up colonoscopy may affect the estimates of reduction in colorectal cancer incidence demonstrated by the National Polyp Study. While an 80% compliance rate for follow up(More)
The development of rapid and effective methods to detect water- and food-borne enteric viruses is important for the prevention and control of mass infection. This study represents an attempt to develop a reliable cell culture-based detection system and optimize an effective and rapid protocol for the assaying of environmental samples for the presence of(More)
The occurrence of human norovirus (NoV) genogroup I (GI) and genogroup II (GII) strains was investigated in Korea. Between 2007 and 2010, 265 samples were collected from 89 Korean water source locations. NoV GI was detected in 4.5% and NoV GII in 1.5%. Samples collected in winter had the highest occurrence; 9.4% for NoV GI and 6.3% for NoV GII. NoV GI(More)
