OBJECTIVES Shigellosis is an important cause of bloody diarrhoea in all age groups, especially in children. A retrospective study was done to analyse the pattern of shigella isolates and the antimicrobial susceptibility trend of these shigella isolated at different hospitals of Nepal from Jan, 2003- Dec, 2005. MATERIALS AND METHODS A total of 118 Shigella species isolated at nine different ho...

BACKGROUND The entire gastrointestinal tract is protected by a mucous layer, which contains complex glycoproteins called mucins. MUC2 is one such mucin that protects the colonic mucosa from invading microbes. The initial interaction between microbes and mucins is an important step for microbial pathogenesis. Hence, it was of interest to investigate the relationship between host (mucin) and path...

1. Anti-Shiga bacteriophage injected into the general circulation can multiply in the brain of mice infected intracerebrally with Shigella dysenteriae. 2. Under proper conditions, the injection of active bacteriophage into the general circulation can protect mice against an otherwise fatal intracerebral infection with Shigella dysenteriae. 3. The protection so induced appears to depend upon the...

Acute infectious diarrhea (AID) can cause severe diarrhea which is called shigellosis. Shigella spp. are a group of pathogenic bacteria transmitted through contaminated food [1, 2]. This group of bacteria causes about 165 million cases of diarrhea each year, out of which 163 million occur in developing countries, and 1.5 million in industrialized nations [3]. Shigella species are mainly transmi...

INSERM U 458, HBpitaI Robert Debre, Paris, France The differentiation between Shigella subspecies, and the phylogenetic position of Shigella clones within Escherichia coli clones was determined by analysis of restriction fragment length polymorphisms of rDNA (ribotyping). Seventy-f ive Shigella strains belonging to the four subspecies and 13 enteroinvasive Em coli (EIEC) strains were compared w...

We describe a strain of Shigella dysenteriae serotype 7 which had novel biochemical and genetic characters. Unlike other S. dysenteriae, it produced gas, fermented mannitol, was a late-lactose fermenter and harboured the set 1A and set 1B genes. The significance of such atypical strains is that they are difficult to identify. If such strains are missed, they could prove to be a serious public h...

The differentiation between Shigella subspecies, and the phylogenetic position of Shigella clones within Escherichia coli clones was determined by analysis of restriction fragment length polymorphisms of rDNA (ribotyping). Seventy-five Shigella strains belonging to the four subspecies and 13 enteroinvasive E. coli (EIEC) strains were compared with the 72 E. coli strains of the ECOR collection, ...

Molecular study of Shigella dysenteriae Aminoglycoside Resistance Genes Isolated from Children and its Expression Under the Influence Curcumin Nanoparticle

Background and Aims: Shigellosis is an acute gastroenteritis and Invasion plasmid antigen C (IpaC) is the first effector protein for Shigella invasion of intestinal cells. Among lactic acid bacteria, Bifidobacterium lactis (B. lactis) has received increasing attention for protection of a potential host against gastrointestinal infections. The aim of this study was to investigate the inhibitory ...

cholera toxin b subunit (ctxb) is a homopantameric, nontoxic subunit of cholera toxin that is responsible for its binding to the cell and has been known as a mucosal adjuvant for vaccines that could increase homoral and mocusal immunity response. in this work, the ctxb gene was fused to the stxb gene from shigella dysenteriae type i a vaccine antigen candidate against this pathogen, by a nonfur...
