INTRODUCTION The Shigella spp. is an organism with an ongoing changing resistance pattern to different antibiotics, thus making its appropriate treatment difficult. Nalidixic acid has been one of the most common agents used for the treatment of shigellosis. Recently, some studies have reported an emerging resistance to this agent. METHODS In this study, we compared the resistance of Shigella ...
Outer membrane blebs are naturally shed by Gram-negative bacteria and are candidates of interest for vaccines development. Genetic modification of bacteria to induce hyperblebbing greatly increases the yield of blebs, called Generalized Modules for Membrane Antigens (GMMA). The composition of the GMMA from hyperblebbing mutants of Shigella flexneri 2a and Shigella sonnei were quantitatively ana...
AIM The aim of this study was to determine the incidence of Shigella species and their antimicrobial susceptibility patterns in hospitalized children with Shigellosis in Abadan, Iran. BACKGROUND Shigellosis is caused by different species of Shigella and one of the most common causes of diarrhea in children. This disease is endemic in many developing countries including Iran. PATIENTS AND ME...
background and objectives: the emergence of extended-spectrum β-lactamase (esbl)-producing shigella spp. is of increasing clinical concern specially in children worldwide. the aim of this study was to investigate the occurrence of extended-spectrum β-lactamase producing shigella spp. in tehran, iran. materials and methods: the study included all shigella isolates recovered from pediatric patie...
background and objectives: strains of shigella spp. can cause shigellosis, or bacillary dysentery.that is a public health problem worldwide. the aim of this study was to describe the population structure and genetic relatedness of multidrug resistant s. sonnei and s. flexneri isolated during a one year period from children with diarrhea in tehran, iran. materials and methods: a total of 70 shig...
BACKGROUNDS Shigellosis remains an important public health problem in developing countries with S. sonnei and S. flexneri in US, Europe and in Asian countries being of importance. OBJECTIVES This study evaluates the protective effect of Lactobacillus casei cell-free culture supernatants (CFCS) against multiple drug resistance (MDR) clinical samples of Shigella sonnei and Shigella flexneri in ...
Acute infectious gastroenteritis is one of the most common infectious diseases of humans in the world. Diarrheal disease still ranks very high as a major cause of illness and death especially in developing nations. This study has been carried out to investigate enteropathogenic bacteria isolated from 2517 specimens of patients with diarrhea. The results obtained are as follow: Salmonella typhim...
Background and Aim: In today’s world, antibiotic resistance is inevitable. This has been the case since the discovery of antibiotics. The aim of this research is to study serotyping and multiple antibiotic resistance pattern of Shigella sonnei isolated from diarrheal stool of patients hospitalized in Children’s Medical Center in Tehran. Materials and Methods: In this descriptive study, 600 di...
OBJECTIVES The genus Shigella comprises the most infectious and diarrheagenic bacteria causing severe diseases, mostly in children under five years of age. This study aimed to detect nine virulence genes (ipaBCD, VirA, sen, set1A, set1B, ial, ipaH, stx, and sat) in Shigella species (spp.) using multiplex polymerase chain reaction (MPCR) and to determine the relation of Shigella spp. from pediat...
