characterization of toxin-antitoxin (ta) systems in pseudomonas aeruginosa clinical isolates in iran
conclusions based on the presence of ta systems in the majority of p. aeruginosa isolates, these could be used as a novel target for antimicrobial therapy. results our results showed that in the 174 p. aeruginosa isolates, relbe and higba were universal, but parde was less prevalent. both of the flanking regions of the parde genes in all positive isolates were amplified. the flanking regions of...
background : unfortunately, antibiotic resistance has become an increasingly critical problem in many countries like iran. since there are very few published data on antibiotics resistance in alborz province, the aim of this study was to survey the pattern of antimicrobial resistance and prevalence detection of tem-type beta-lactamases among clinical isolates of escherichia coli using univer...
background: clarithromycin resistance in helicbacter pylori has been found to be associated with point mutations in 23s rrna gene leads to reduced affinity of the antibiotic to its ribosomal target or changing the site of methylation. the aim of this study was to determine the most important point mutations in 23s rrna gene in h. pylori that are closely related to clarith-romycin resistance amo...
abstractbackground and objective: satellite cells are muscle stem cells that enter cycle cells due to myotrauma. among activation and proliferation indices of these cells is increase of myod gene expression. but these are contradiction in response of this gene to resistance exercise in fast and slow fibers. thus, the aim of this study was to evaluate the effect of a single bout of resistance ex...
Background: Clarithromycin resistance in Helicbacter pylori has been found to be associated with point mutations in 23s rRNA gene leads to reduced affinity of the antibiotic to its ribosomal target or changing the site of methylation. The aim of this study was to determine the most important point mutations in 23s rRNA gene in H. pylori that are closely related to clarith-romycin resistance amo...
staphylococcus aureus is a hazard to human health since they can cause a wide variety of hospital-associated infections ranging from minor skin infections to post-operative wound infections and food poisoning which produces many different virulence factors, including enterotoxins (ses). although studies have been done regarding the difference between virulence factors of sensitive st...
a stable agrobacterium-mediated transformation system was established using bialaphos as the selective agent in soybeans [glycine max (l.) merr.]. the cotyledonary node explants of the soybean cultivar ‘ny-1001’ were inoculated with the agrobacterium tumefaciens strain eha105, harboring the vector pcambia3301 containing the gus gene as the reporter gene and the bar gene conferring bialaphos res...
p. atlantica subsp. kurdica, with the local name of baneh, is a wild medicinal plant which grows in kurdistan, iran. the identification of resistance gene analogs holds great promise for the development of resistant cultivars. a pcr approach with degenerate primers designed according to conserved nbs-lrr (nucleotide binding site-leucine rich repeat) regions of known disease-resistance (r) gene...
Background and Aim: In the last few decades co-trimoxazole, an antibacterial combination of trimethoprim and sulfamethoxazole, has been used for treatment of bacterial infections, but due to the vast usage of these drugs, resistant strains have appeared throughout the world. One of the reasons for resistance to co-trimoxazole is related to drf genes, which are responsible for trimethoprim resis...
background: in order to deworm the ruminants especially of sheep in iran, consumption of benzimidazoles has more than 2 decades history and today farmers are using imidazothiazoles, macrocyclic lactones and mostly benzimidazole compounds (bzs) to treat infected farm animals. it has been demonstrated that the most common molecular mechanism leading to bzsresistance in haemonchus contortus is a ...
