Martin Eichner, Scott F. Dowell, Nina Firese
Osong Public Health Res Perspect. 2011;2(1):3-7.   Published online June 30, 2011
Objectives

Ebola hemorrhagic fever has killed over 1300 people, mostly in equatorial Africa. There is still uncertainty about the natural reservoir of the virus and about some of the factors involved in disease transmission. Until now, a maximum incubation period of 21 days has been assumed.

Methods

We analyzed data collected during the Ebola outbreak (subtype Zaire) in Kikwit, Democratic Republic of the...

Genotypic Characterization of Vibrio vulnificus Clinical Isolates in Korea
Hye Sook Jeong, Jun Young Kim, Se Mi Jeon, Mi Sun Park, Seong Han Kim
Osong Public Health Res Perspect. 2011;2(1):8-14.   Published online June 30, 2011
Objectives

Vibrio vunificus is known to cause septicemia and severe wound infections in patients with chronic liver diseases or an immuno-compromised condition. We carried out the molecular characterization of V. vulnificus isolates from human Vibrio septicemia cases based on pulsed-field gel electrophoresis (PFGE) using NotI and SfiI.

Methods and Results

PFGE was used to characterize a total of 78 strains from clinical cases...

Osong Public Health Res Perspect. 2011;2(1):15-22.   Published online June 30, 2011
Objectives

We aimed to evaluate the pathogenesis and chronologic localization of human influenza A (H1N1) virus in experimentally infected cotton rats.

Methods

The animals were intranasally inoculated with 107 plaque-forming units of A/Solomon Islands/3/2006 (H1N1) influenza virus and evaluated for pathogenicity for a period of 28 days. Virus replication kinetics and pathological properties were assessed chronologically. Acute antiviral responses were evaluated by mean of...

Infectivity of Homologous Recombinant HIV-1 Pseudo-virus with Reverse Transcriptase Inhibitor-related Mutations from Highly Active Antiretroviral Therapy Experienced Patients
Oh-Kyung Kwon, Ju-yeon Choi, Eun-Jin Kim, Sung Soon Kim
Osong Public Health Res Perspect. 2011;2(1):23-28.   Published online June 30, 2011
Objectives

In this study, the viral fitness of pseudo-viruses with a drug-resistant site in the reverse transcriptase (RT) region of the genome was investigated. The pseudo-viruses were derived from highly active antiretroviral therapy (HAART)-experienced HIV/AIDS patients.

Methods

HIV-1 RNA was extracted from the plasma of HAART-experienced (KRB9149, KRB7021, KRC1097) and HAART-naïve (KRC5180, KRC5123) HIV-1 patients. The RT gene from the extracted viral RNA...

Serological Detection of Lyme Borreliosis Agents in Patients From Korea, 2005–2009
Sang-Hee Park, Kyu-Jam Hwang, Hyuk Chu, Mi-Yeoun Park
Osong Public Health Res Perspect. 2011;2(1):29-33.   Published online June 30, 2011
Objectives

Laboratory tests are now being used to identify seropositive cases in patients suspected of having a Lyme borreliosis (LB) infection. From 2005 to 2009, we analyzed the serological and epidemiological characteristics of 53 LB positive cases in Korea using immunoblot assay.

Methods

During the five-year study period, a total of 1897 serum samples from suspected LB cases were referred to us for...

Identification of Dengue Type 1 Virus (DENV-1) in Koreans Traveling Abroad
Young Eui Jeong, Yeon Hee Kim, Jung Eun Cho, Myung Guk Han, Young Ran Ju
Osong Public Health Res Perspect. 2011;2(1):34-40.   Published online June 30, 2011
Objectives

To date, no indigenous dengue virus (DENV) transmissions have been reported in Korea. However, imported dengue infections have been diagnosed in travelers returning from endemic areas. This study presents the first virological evidence of travel-associated DENV importation into South Korea.

Methods

From January 2004 to June 2006, a total of 278 serum samples from 245 patients with suspected dengue fever were tested...

Prevalence of Antibiotic Resistance in Escherichia coli Fecal Isolates From Healthy Persons and Patients With Diarrhea
Seung-Hak Cho, Yeong-Sik Lim, Mi-Sun Park, Seong-Han Kim, Yeon-Ho Kang
Osong Public Health Res Perspect. 2011;2(1):41-45.   Published online June 30, 2011
Objectives

This study aimed to investigate the prevalence of antibiotic resistance in fecal Escherichia coli isolates from healthy persons and patients with diarrhea.

Methods

E. coli isolates (n = 428) were obtained from fecal samples of apparently healthy volunteers and hospitalized patients with diarrhea. Susceptibility patterns of isolates to 16 antimicrobial agents were determined by agar disc diffusion.

Results

Most E. coli isolates exhibited less than 10%...

Seroprevalence of Hepatitis A and E Viruses Based on the Third Korea National Health and Nutrition Survey in Korea
Haesun Yun, Hyeok-Jin Lee, Doosung Cheon, Chaeshin Chu, Kyung Won Oh, Young Taek Kim, Youngmee Jee
Osong Public Health Res Perspect. 2011;2(1):46-50.   Published online June 30, 2011
Objectives

The purpose of this study was to investigate the seroprevalence of hepatitis A virus (HAV) and hepatitis E virus (HEV) in Korea during 2005.

Methods

Study subjects were selected from across Korea using a stratified multistage probability sampling design, and HAV and HEV seroprevalence was compared on the basis of sex, age, and residency. A total of 497 rural and urban people...

Mathematical Modeling of Vibrio vulnificus Infection in Korea and the Influence of Global Warming
Chaeshin Chu, Younghae Do, Yongkuk Kim, Yasuhisa Saito, Sun-Dong Lee, Haemo Park, Jong-Koo Lee
Osong Public Health Res Perspect. 2011;2(1):51-58.   Published online June 30, 2011
Objectives

To investigate the possible link between Vibrio vulnificus population size in seawater and water temperature.

Methods

We collected incidence and water temperature data in coastal regions of Korea and constructed a mathematical model that consisted of three classes; susceptible fish, infected fish available to humans, and infected humans.

Results

We developed a mathematical model to connect V. vulnificus incidence with water temperature using estimated...
