Genetic structure of the nadA and nadB antivirulence loci in Shigella spp.
نویسندگان
چکیده
Comparison of nadA and nadB in 14 Shigella strains and enteroinvasive Escherichia coli versus E. coli showed that at least one locus is altered in all strains. These observations explain the characteristic nicotinic acid auxotrophy of Shigella organisms and are consistent with the previously identified antivirulence nature of these genes for these pathogens.

Diversity of Variable Number Tandem Repeat Loci in Shigella Species Isolated From Pediatric Patients
Multilocus variable number tandem repeat (VNTR) analysis (MLVA) is a new typing method with several advantages compared to other methods. Dissemination of Shigella is highly significant in developing countries. Whilst Shigella is becoming increasingly important as an etiologic agent of pediatric shigellosis in Iran, little is known about the genetic diversity of the local strains. Therefore, th...
متن کاملPathoadaptive mutations that enhance virulence: genetic organization of the cadA regions of Shigella spp.
Pathoadaptive mutations improve the fitness of pathogenic species by modification of traits that interfere with factors (virulence and ancestral) required for survival in host tissues. A demonstrated pathoadaptive mutation is the loss of lysine decarboxylase (LDC) expression in Shigella species that have evolved from LDC-expressing Escherichia coli. Previous studies demonstrated that the produc...
متن کاملPolymerase chain reaction method for the rapid detection of virulent Shigella spp.
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...
متن کاملCurli loci of Shigella spp.
An unstable chromosomal element encoding multiple antibiotic resistance in Shigella flexneri serotype 2a was found to include sequences homologous to the csg genes encoding curli in Escherichia coli and Salmonella enterica serovar Typhimurium. As curli have been implicated in the virulence of serovar Typhimurium, we investigated the csg loci in all four species of Shigella. DNA sequencing and P...

This study was carried out to investigate the genetic diversity and population structure of 90 specimens of Oxynoemacheilus argyrogramma collected from Sepidbarg, Gamasiab and Ghaleji rivers, in the west of Iran. Analyses using three microsatellite loci indicated that the average number of alleles in the population was 12, which was well above the reported values for freshwater fishes. The expe...
