conclusions the outcome of this study indicates a higher discriminatory power of the rflp analysis based on the spa gene compared to the coa gene. moreover, the results of our study reveal that the resistance rate of s. aureus to some antimicrobial agents including linezolid is a growing concern. background antibiotic resistant staphylococcus aureus is a serious public health problem worldwide....
Background and Objective: Salmonella spp. are enteric pathogens with a worldwide distribution comprising a large number of serovars characterized by different hosts and distribution. Among Salmonella spp., the number of infections and diseases caused by the serotype Salmonella enterica serovar Infantis started to increase significantly in the last decade. The aim of this study was to investigat...
Rhizobia are a widely distributed and abundant soil bacteria belonging to the alpha subclass of the Proteobacteria. The aim of this study was the estimation of rhizobial diversity in different genera using several molecular markers for genomic fingerprinting and the detection of certain symbiotic properties of rhizobia. Phage typing was done in order to detect different susceptibilities to atta...
Mobile genetic elements (MGEs) and genetic rearrangement are considered as major driving forces of bacterial diversification. Previous comparative genome analysis of Porphyromonas gingivalis, a pathogen related to periodontitis, implied such an important relationship. As a counterpart system to MGEs, clustered regularly interspaced short palindromic repeats (CRISPRs) in bacteria may be useful f...
Background. Escherichia coli is a highly clonal pathogen. Extraintestinal isolates belong to a limited number of genetically related groups, which often exhibit characteristic antimicrobial resistance profiles. Methods. We developed a rapid clonotyping method for extraintestinal E coli based on detection of the presence or absence of 7 single nucleotide polymorphisms (SNPs) within 2 genes (fu...
The most common complications of varicella are bacterial skin and soft tissue infections, generally due to Staphylococcus aureus and group A beta-hemolytic streptococci. The aim of this study was to characterize the toxin and antibiotic resistance profiles of S. aureus isolates involved in varicella complications. Between 2002 and 2007, the French Reference Centre for Staphylococci collected 58...
