The role of SOS and flap processing in microsatellite instability in Escherichia coli.

Survey of bacteria associated with abdominal flap of freshwater crab (Potamon ebonyicum) at Ebonyi River basin Nigeria

Ebonyi River basin of south east Nigeria is home to the freshwater crab Potamon ebonyicum, which are consumed indiscriminately by inhabitants and tourists. Bulk of the crab meat is obtained by crabbing. A preliminary survey of pathogenic bacteria associated with vulnerable morphological part of the crab species was carried out in the basin. Bacteria were isolated from abdominal flaps of the mal...

Using L-arabinose for Production of Human Growth Hormone in Escherichia coli, Studying the Processing of gIII::hGH Precursor

Comparison of responses to double-strand breaks between Escherichia coli and Bacillus subtilis reveals different requirements for SOS induction.

DNA double-strand breaks are particularly deleterious lesions that can lead to genomic instability and cell death. We investigated the SOS response to double-strand breaks in both Escherichia coli and Bacillus subtilis. In E. coli, double-strand breaks induced by ionizing radiation resulted in SOS induction in virtually every cell. E. coli strains incapable of SOS induction were sensitive to io...

A preliminary study of microsatellite instability analysis in different genotypes of p53 codon 72 in breast invasive ductal carcinomas

  Abstract   Background: The polymorphic variants at codon 72 of the p53 gene, encoding either   proline or arginine at residue 72, produce marked change in the structure of p53.   From the evidence that the DNAmismatch repair system and p53 interact to maintain   genomic integrity, we hypothesized that the codon 72 variation may influence the   prevalence of microsatellite instability a featur...

Prevalence, Antimicrobial Resistance, and Molecular Characterization of Escherichia coli Isolated from Food Contact Surfaces in Seafood Pre-Processing Plants (India)

Background: The survival of pathogens in biofilms poses a threat to food safety. The aim of this study was to determine prevalence, antimicrobial resistance, and molecular characterization of Escherichia coli strains. Methods: Swab samples (n=144) were collected from biofilm formed on food contact surfaces in seafood pre-processing plant in India. E. coli was isolated and identified using uid ...
