Characterization of Antimicrobial Susceptibility, Extended-Spectrum β-Lactamase Genes and Phylogenetic Groups of Enteropathogenic Escherichia coli Isolated from Patients with Diarrhea
Erfaneh Jafari, Saeid Mostaan, Saeid Bouzari
Osong Public Health Res Perspect. 2020;11(5):327-333.   Published online October 22, 2020
Objectives

Infectious diarrhea is one of the most common causes of pediatric death worldwide and enteropathogenic Escherichia coli (EPEC) is one of the main causes. There are 2 subgroups of EPEC, typical and atypical, based on the presence or absence of bundle forming pili (bfp), of which atypical EPEC is considered less virulent, but not less pathogenic. Antimicrobial resistance towards atypical...

Immunological Profile and Bacterial Drug Resistance in Pregnant Women: A Cross Sectional Study
Ornella JT Ngalani, Wiliane JT Marbou, Armelle Tsafack Mbaveng, Victor Kuete
Osong Public Health Res Perspect. 2020;11(5):319-326.   Published online October 22, 2020
Objectives

This study aimed to investigate the immunological and bacterial profiles in pregnant women of Bafang-Cameroon.

Methods

Stool and midstream urine were cultured using specific culture media. The disk diffusion method was used for the antimicrobial susceptibility test. T-cell lymphocyte counts (CD3, CD4 and CD8), white blood cell counts, sensitive C-reactive protein, and interleukin-6, were measured by flow cytometry, optical detection, and the...

Association between Beta-lactam Antibiotic Resistance and Virulence Factors in AmpC Producing Clinical Strains of P. aeruginosa
Sanaz Dehbashi, Hamed Tahmasebi, Mohammad Reza Arabestani
Osong Public Health Res Perspect. 2018;9(6):325-333.   Published online December 31, 2018
Objectives

The purpose of this study was to determine the presence of IMP and OXA genes in clinical strains of Pseudomonas aeruginosa (P. aeruginosa) that are carriers of the ampC gene.

Methods

In this study, 105 clinical isolates of P. aeruginosa were collected. Antibiotic resistance patterns were determined using the disk diffusion method. The strains carrying AmpC enzymes were characterized by a combination...

Phenotypic Assays to Determine Virulence Factors of Uropathogenic Escherichia coli (UPEC) Isolates and their Correlation with Antibiotic Resistance Pattern
Mohsen Tabasi, Mohammad Reza Asadi Karam, Mehri Habibi, Mir Saeed Yekaninejad, Saeid Bouzari
Osong Public Health Res Perspect. 2015;6(4):261-268.   Published online August 31, 2015
Objectives

Urinary tract infection caused by uropathogenic Escherichia coli (UPEC) strains is one of the most important infections in the world. UPEC encode widespread virulence factors closely related with pathogenesis of the bacteria. The purpose of this study was to evaluate the presence of different phenotypic virulence markers in UPEC isolates and determine their correlation with antibiotic resistance pattern.

Methods

UPEC isolates from...

Antibiotic Resistance of Acinetobacter baumannii in Iran: A Systemic Review of the Published Literature
Jale Moradi, Farhad B. Hashemi, Abbas Bahador
Osong Public Health Res Perspect. 2015;6(2):79-86.   Published online April 30, 2015
Objectives

Acinetobacter baumannii is a bacterium responsible for health care-associated infections, and it frequently develops multiple drug resistance (MDR). The prevalence of antibiotic-resistant A. baumannii in Iran has increased, and this may cause significant clinical problems. Therefore, in order to elucidate the development of antibiotic resistance, we performed a systematic review of the literature published on antibiotic-resistant A. baumannii reported in...

Comparison of Antimicrobial Resistance in Escherichia coli Strains Isolated From Healthy Poultry and Swine Farm Workers Using Antibiotics in Korea
Seung-Hak Cho, Yeong-Sik Lim, Yeon-Ho Kang
Osong Public Health Res Perspect. 2012;3(3):151-155.   Published online June 30, 2012
Objectives

The aim of this study is to compare the antibiotic resistance of Escherichia coli isolates from faecal samples of workers who often use antibiotics.

Methods

A total of 163E coli strains isolated from faecal samples of livestock workers (poultry and swine farm workers) and restaurant workers in the same regions as a control group were analyzed by agar disc diffusion to determine...

A diversity of Antibiotic-resistant Staphylococcus spp. in a Public Transportation System
Pamela J. Yeh, Dawn M. Simon, Jess A. Millar, H. Forrest Alexander, Darleen Franklin
Osong Public Health Res Perspect. 2011;2(3):202-209.   Published online December 31, 2011
Objectives

Our goal was to determine the diversity and abundance of Staphylococcus bacteria on different components of a public transportation system in a mid-sized US city (Portland, Oregon) and to examine the level of drug resistance in these bacteria.

Methods

We collected 70 samples from 2 cm × 4 cm sections from seven different areas on buses and trains in Portland, USA, taking...

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%...
