bacillary dysentery, or shigellosis, is a disease of humans in which the colonic epithelium is invaded by bacteria and subjected to inflammatory destruction. the aim of this study was to develop a polymerase chain reaction(pcr) test for detection of virulent shigella spp.. for this purpose, the primers were designed to amplify a 526-bp internal region of the shigella spp. icsa gene, which encod...

Shigellosis produces inflammatory reactions and ulceration on the intestinal epithelium followed by bloody or mucoid diarrhea. It is caused by enteroinvasive E. coli (EIEC) as well as any species of the genus Shigella, namely, S. dysenteriae, S. flexneri, S. boydii, and S. sonnei. This current species designation of Shigella does not specify genetic similarity. Shigella spp. could be easily dif...

INTRODUCTION The prevalence and antimicrobial susceptibility patterns of the bacterial enteropathogens Vibrio cholerae, Salmonella species and Shigella species were investigated. METHODOLOGY A total of 877 stool samples were received for culture at the National Public Health Laboratory (NPHL), Kathmandu, Nepal, during January 2002 to December 2004, from diarrhoea patients attending Shukraraj ...

in recent years, the importance of shigella as an enteric pathogen with global impact has been increasingly recognized. in this study, serogroup distribution of shigella isolated from clinically diagnosed cases of gastroenteritis and acute diarrhea in tehran, capital of iran was investigated between december 2002 and november 2003. fecal specimens and rectal swabs were cultured for shigella spp...

In this study, the serogroup and susceptibility patterns of Shigella and Salmonella spp. isolated from stool cultures were determined using standard laboratory procedures. Among the 76 Shigella isolates serogroup B (Sh. flexeneri) was the most prevalent species (54.0%) and among the 37 Salmonella strains serogroup B was also the most prevalent (81.1%). Antibiograms of Shigella and Salmonella sp...

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 ...

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...

OBJECTIVES Gastrointestinal tract infection is still one of the serious public health problems in many geographic areas and is endemic in most countries including Iran. Early detection of the gastrointestinal tract pathogens can be extremely important. The aim of the current study was to apply a shortened time-multiplex polymerase chain reaction (PCR) for rapid and simultaneous detection of Sal...

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...
