[ 1 ] - Amino acid Substitution Mutations Analysis of gyrA and parC Genes in Clonal Lineage of Klebsiella pneumoniae conferring High-Level Quinolone Resistance
Background: Emergence Klebsiella pneumoniae resistant to quinolone antibiotics due to mutations in gyrA and parC genes created problem for treatment of patients in different hospitals in Iran. The objective of this study was to determine the amino acid substitutions of GyrA and ParC proteins in certain clonal lineages of the K. pneumoniae conferring high level quinolone resistance. Methods: One...
[ 2 ] - بررسی فنوتیپی و ژنوتیپی مقاومت به آنتیبیوتیکهای کینولون در ایزولههای بالینی اشریشیاکلی جدا شده از عفونت ادراری افراد بستری در بیمارستان های شهر تهران در سال 1396
Background & Aim: Antibiotic resistance to quinolones as a therapeutic agent of urinary tract infection in increasing in the world. Thus, this study was designed to evaluate the resistance to quinolone antibiotics in Escherichia coli isolated from urinary tract infection of hospitalized patients in Tehran, Iran in 2017. Methods: In the present study, 150 E. coli isolates was collected from uri...
[ 3 ] - Cloning, expression, purification and the study of immunotherapy status of TGFαL3-SEB chimeric protein in breast cancer treatment
Background & Aim: Bacterial superantigens, stimulate polyclonal T cells irrespective of their antigen specificity, resulting in a massive release of cytokines from T cells and monocytes, and suggest that that they could be candidates of new antitumor agents. Recent attempts have been done to specifically target superantigens towards tumors. Here, we evaluate TGFαL3-SEB fusion protein as a new a...
[ 4 ] - Stereochemical Trajectories of a Two-Component Regulatory System PmrA/B in a Colistin-Resistant Acinetobacter baumannii Clinical Isolate
Background: There is limited information on the 3D prediction and modeling of the colistin resistance-associated proteins PmrA/B TCS in Acinetobacter baumannii. We aimed to evaluate the stereochemical structure and domain characterization of PmrA/B in an A. baumannii isolate resistant to high-level colistin, using bioinformatics tools. Methods: The species of the isolate and its susceptibility ...
