Introduction: This study was conducted to determine the frequency and pattern of antimicrobial susceptibility of Shigella spp. isolated from pediatric hospital in two different time periods between March 1995 to March 1999 and March 2009 to March 2013 in North-West of Iran. Methods: The stool specimens were collected and examined for shigellosis by biochemical tests, and antibiogram was conduct...
Shigella is a pathovar of Escherichia coli comprising four groups, Shigella flexneri, Shigella sonnei, Shigella dysenteriae, and Shigella boydii, each of them, with the exception of S.sonnei, comprising several serotypes. Shigella accounts for the majority of dysentery causing infections occurring world-wide each year. Recent advancements in the Shigella field have led to a better understanding...
Background & Objective: Shigella are Gram negative bacteria capable of inducing their entry into non-phagocytic cells via secretion of various effector proteins called invasion plasmid antigens (Ipas). The most important of them is VirG protein. Live attenuated Shigella vaccines have indicated promise in inducing protective immune responses in human clinical trials. In current situation, const...
AIM This study aims to determine the serogroup distribution and molecular diagnosis, as well as antimicrobial resistance profiles among Shigella spp. isolated from patients with diarrhea in Kerman, southeast of Iran. BACKGROUND Shigella species are frequent cause of bacterial dysentery worldwide. Previous studies have been reported that S. sonnei and S. flexneri are the most prevalent serogro...
BACKGROUND & OBJECTIVES The four species of the genus Shigella, namely, S. dysenteriae , S. flexneri, S. boydii and S. sonnei cause a wide spectrum of illness from watery diarrhoea to severe dysentery. Genomes of these four species show great diversity. In this study, NotI, XbaI or I-CeuI restriction enzyme digested genomes of two Shigella dysenteriae isolates belonging to the serotypes 2 and 7...
The aims of this study were to determine the distribution of serogroups and serotypes as well as the antimicrobial resistance pattern of Shigella isolates from Gondar patients with acute diarrhea. A cross-sectional study was conducted from August 2006 to February 2008. Stool specimens were received from study subjects and cultured. Isolates were confirmed by biochemical and serological tests. T...
BACKGROUND AND OBJECTIVES Shigellosis is an acute gastroenteritis that is one of the most common causes of morbidity and mortality in children with diarrhea in developing countries. The purpose of this study was to describe the distribution of Shigella serogroups and serotypes and their antibacterial drug resistance profiles. MATERIALS AND METHODS Fecal samples of all children suffering from ...
BACKGROUND AND PURPOSE Shigellosis is a major health problem in developing countries, causing 91 million episodes and 414,000 deaths in Asia annually. Because of increasing trends towards drug resistance, this study was undertaken to monitor local resistance patterns of Shigella isolates from 8 Asian countries. METHODS Ninety eight Shigella isolates collected from 8 centers in 8 Asian countri...
Shigella flexneri causes shigellosis, severe and potentially life-threatening diarrhea, and accounts for 18% of shigellosis cases in the United States. Here, we present the 4.51-Mbp genome assembly of S. flexneri ATCC 12022, a quality control and reference strain, in 10 scaffolds.
We report a case of splenic abscess from which only Shigella flexneri (serotype 1a) and Bacteroides fragilis were isolated. The patient was a 59-year-old diabetic female who displayed minimal gastrointestinal symptoms. The S. flexneri isolate was resistant to chloramphenicol and tetracycline. The possible synergistic relationship between the two organisms is discussed.
