Genome Sequencing Analysis of Atypical Shigella flexneri Isolated in Korea
Nan-Ok Kim, Hae-young Na, Su-Mi Jung, Gyung Tae Chung, Hyo Sun Kawk, Sahyun Hong
Osong Public Health Res Perspect. 2017;8(1):78-85.   Published online February 28, 2017
Objectives

An atypical Shigella flexneri strain with a plural agglutination pattern [i.e., reacting not only with serum samples containing type antigen II but also with serum samples containing group antigens (3)4 and 7(8)] was selected for genome sequencing, with the aim of obtaining additional comparative information about such strains.

Methods

The genomic DNA of atypical S. flexneri strain NCCP 15744 was sequenced using...

Surveillance of Bacillus cereus Isolates in Korea from 2012 to 2014
Su-Mi Jung, Nan-Ok Kim, Injun Cha, Hae-young Na, Gyung Tae Chung, Hyo Sun Kawk, Sahyun Hong
Osong Public Health Res Perspect. 2017;8(1):71-77.   Published online February 28, 2017
Objectives

To investigate the prevalence and toxin production characteristics of non-emetic and emetic Bacillus cereus strains isolated via the laboratory surveillance system in Korea.

Methods

A total of 667 B. cereus strains were collected by the Korea National Research Institute of Health laboratory surveillance system from 2012 to 2014. The collected strains were analyzed by geographical region, season, patient age, and patient sex....

Brief Report
Occurrence of Norovirus GII.4 Sydney Variant-related Outbreaks in Korea
Sunyoung Jung, Bo-Mi Hwang, Hyun Ju Jeong, Gyung Tae Chung, Cheon-Kwon Yoo, Yeon-Ho Kang, Deog-Yong Lee
Osong Public Health Res Perspect. 2015;6(5):322-326.   Published online October 31, 2015
Human noroviruses are major causative agents of food and waterborne outbreaks of nonbacterial acute gastroenteritis. In this study, we report the epidemiological features of three outbreak cases of norovirus in Korea, and we describe the clinical symptoms and distribution of the causative genotypes. The incidence rates of the three outbreaks were 16.24% (326/2,007), 4.1% (27/656), and 16.8% (36/214), respectively. The...
Epidemics of Norovirus GII.4 Variant in Outbreak Cases in Korea, 2004–2012
Sunyoung Jung, Hyun Ju Jeong, Bo-Mi Hwang, Cheon-Kwon Yoo, Gyung Tae Chung, Hyesook Jeong, Yeon-Ho Kang, Deog-Yong Lee
Osong Public Health Res Perspect. 2015;6(5):318-321.   Published online October 31, 2015
Norovirus GII.4 is recognized as a worldwide cause of nonbacterial outbreaks. In particular, the GII.4 variant occurs every 2–3 years according to antigenic variation. The aim of our study was to identify GII.4 variants in outbreaks in Korea during 2004–2012. Partial VP1 sequence of norovirus GII.4-related outbreaks during 2004–2012 was analyzed. The partial VP1 sequence was detected with reverse transcription-polymerase...

Enteric Bacteria Isolated from Diarrheal Patients in Korea in 2014
Nan-Ok Kim, Su-Mi Jung, Hae-Young Na, Gyung Tae Chung, Cheon-Kwon Yoo, Won Keun Seong, Sahyun Hong
Osong Public Health Res Perspect. 2015;6(4):233-240.   Published online August 31, 2015
Objectives The aim of this study was to characterize the pathogens responsible for causing diarrhea according to season, region of isolation, patient age, and sex as well as to provide useful data for the prevention of diarrheal disease. Methods Stool specimens from 14,886 patients with diarrhea were collected to identify pathogenic bacteria from January 2014 to December 2014 in Korea. A total of...

Investigation of Biofilm Formation and its Association with the Molecular and Clinical Characteristics of Methicillin-resistant Staphylococcus aureus
Jeong-Ok Cha, Jae Il Yoo, Jung Sik Yoo, Hae-Sun Chung, Sun-Hee Park, Hwa Su Kim, Yeong Seon Lee, Gyung Tae Chung
Osong Public Health Res Perspect. 2013;4(5):225-232.   Published online October 31, 2013
Objectives To investigate the biofilm-forming related factors against MRSA bloodstream isolates and evaluates their clinical features and treatment outcomes by biofilm production. Methods We collected 126 consecutive methicillin-resistant Staphylococcus aureus (MRSA) causing blood stream infections (BSIs) at 10 tertiary hospitals from 2007 to 2009. We investigated biofilm-forming ability using a microtiter plate assay, and molecular characteristics including multilocus sequence typing, staphylococcal cassette chromosome...

Alterations of gyrA, gyrB, and parC and Activity of Efflux Pump in Fluoroquinolone-resistant Acinetobacter baumannii
Sunok Park, Kyeong Min Lee, Yong Sun Yoo, Jung Sik Yoo, Jae Il Yoo, Hwa Su Kim, Yeong Seon Lee, Gyung Tae Chung
Osong Public Health Res Perspect. 2011;2(3):164-170.   Published online December 31, 2011
Objectives This study investigated the fluoroquinolone-resistant mechanism of 56 clinical cases of A baumannii infection from 23 non-tertiary hospitals, collected between 2004 and 2006. Methods Susceptibility testing was performed by broth microdilution and Epsilometer test. Analyses of quinolone resistance-determining region (QRDR) were done by sequencing. The activity of the efflux pump was measured using inhibitors. Results The sequences from selected 56 isolates were divided into...
