Shigella is the cause of shigellosis or bacillary dysentery, the occurrence of which is estimated to be 165 million cases per year worldwide, resulting in 1.1 million deaths. Rapid and reliable assays for detecting and identifying Shigella in food, environmental and clinical samples are therefore necessary. Shigella species are traditionally identified by their O antigens. This study developed ...
antibiotic resistance in shigella species has been showing a rising trend all over the world. this study was performed to discover the state of antibiotic resistance of shigella species with regards to six common antibiotics in use in iran.
Background and Aim: Food-borne diseases, with an upward trend worldwide, are a major public health issue. On the other hand, resistance to antimicrobial agents is also a global problem. Thus, a knowledge of antibiotic resistance is vital for the proper treatment of food-borne diseases. The aims of this study were to determine the frequency, antimicrobial resistance and serotyping of Shigella-co...
Introduction:Gastroenteritis Shigellosis is caused by Shigella serovars. The purpose this study was to determine the frequency of Shigella species in acute diarrhea caused by consumption of contaminated food in Yazd province. We also invetigated the determining factors of Shigella for antibiotic resistance. Methods: This descriptive study was conducted on 51 outbreaks of food-borne diarrhea f...
due to extension of human life consumer, groundwater resources in recent decades have been increasingly intruded by contaminants. nowadays, the great challenges facing engineers and experts are groundwater protection against contamination inputs and reduction of specific pollutants of these resources. therefore, monitoring and evaluation of aquifer with a view to quantity and quality can play a...
Every year there are estimated 300000 cases of Shigella in the United States (Bennett et al., 1987, Am. J. Prev. Med. 3, 102-114). A beta-poisson model was fit to human dose-response information on pathogenic Shigella using the Maximum Likelihood Estimation technique (Haas, 1983, Am. J. Epidemiol. 118, 573-582). Pooled and separate data sets for the Shigella species were fit to the beta-Poisson...
In developing countries, Shigella is a primary cause of diarrhea in infants and young children. Although antibiotic therapy is an effective treatment for shigellosis, therapeutic options are narrowing due to the emergence of antibiotic resistance. Thus, preventive vaccination could become the most efficacious approach for controlling shigellosis. We have identified several conserved protein ant...
Shigellae cause significant diarrheal disease and mortality in humans, as there are approximately 163 million episodes of shigellosis and 1.1 million deaths annually. While significant strides have been made in the understanding of the pathogenesis, few studies on the genomic content of the Shigella species have been completed. The goal of this study was to characterize the genomic diversity of...
Shigellae infect human intestine and cause intense inflammation and destruction of colonic and rectal mucosa. To model the interactions of shigella with human intestine in vivo, we have studied shigella infection in human intestinal xenografts in severe combined immunodeficient mice (SCID-HU-INT mice). Inoculation of shigella into human intestinal xenografts caused severe inflammation and mucos...
The Shigella genus has historically been separated into four species, based on biochemical assays. The classification within each species relies on serotyping. Recently, genome sequencing and DNA assays, in particular the multilocus sequence typing (MLST) approach, greatly improved the current knowledge of the origin and phylogenetic evolution of Shigella spp. The Shigella and Escherichia gener...
