Background and Objective: AmpC-type beta-lactamases have been implicated in group C of Amber, which includes EBC, CIT, MOX, FOX, DHA, and ACC. The active presence of these plasmid genes in clinical isolates of P.aeruginosa has resulted in resistance to a wide range of antibiotics. Therefore, we aimed to determine the minimum inhibitory concentrations (MIC) of different antibiotic groups in clin...
objective: global surveillance has shown that drug resistant (dr) tuberculosis (tb) is widespread. prompt detection of mycobacterium tuberculosis drug resistance is essential for effective control of tb. the most frequent mutations associated with isoniazid (inh) resistance in mycobacterium are substitutions at codons 315 in the katg gene and the maba-inha promoter region (−15). this survey eva...
background guiana extended-spectrum (ges-2) as one of the extended-spectrum β-lactamases (esbls), produced by pseudomonas aeruginosa, is able to compromise the effectiveness of imipenem and tends to be geographically limited. objectives the aim of this study was to detect the spread of ges-2 β-lactamase gene among esbl- producing p. aeruginosa isolates in a teaching hospital in kashan, iran. ma...
Introduction: Myocyte Enhancer Factor 2 (mef2) gene relates with multiple myogenic transcriptional factors that induces activation Muscle-specific genes. MEF2 contributes in muscular cells development and differentiation as well as in fibers transition in response to stimulants. Therefore, the aim of this study was to evaluate the effect of one bout of resistance exercise (RE) on mef2 gene expr...
the increasing incidence of multi drug resistance tuberculosis (mdr-tb) and extensively drug resistance tb (xdr-tb) worldwide highlight the urgent need to search for newer anti-tuberculosis compounds. it has been determined that pharmaceutical plant, hops ( humulus lupulus ), possesses some antibacterial effect. in this study, the antimycobacterial effect of this plant on rifampin sensitive and...
background: integrons are the major reasons of multidrug resistance (mdr) among enteropathogenic bacteria. occurrence of horizontal gene transfer between integron-carrying microorganisms and other enteric bacteria may increase the rate of emergence of integron-associated antibiotic resistance. objectives: the objective of this study was to investigate class 1 integrons among members of enteropa...
Background. The accumulation of excess triglyceride in the liver and a decrease in brown adipose tissue is related to the fatty liver disease. Regular physical activity can take part in regulating fat oxidation and inhibiting fat accumulation by creating and releasing some myokines. Nevertheless, the effectiveness of each training method in this regard is still not certain. Objective(s). This ...
Background and Objective: Pseudomonas aeruginosa is one of the most important pathogenic bacteria causing infectious diseases that include resistance to many antibiotics. In addition, existence of LasIand AlgD gene contributes to pathogenicity of this bacterium. This study is aimed to investigate the frequency of mentioned genes, antibiotic resistance and a significant relationship between the...
Introduction & Objective: Fluoroquinolones are essential antimicrobial agents used to treat UTIs. Clinical experiences have shown a high rate of antibiotic resistance among uropathogens. These resistance are usually the consequence of mutations involving genes encoding gyrA and parC. The aim of this study was to determine antimicrobial resistance pattern and the presence of mutations in regions...
conclusions biofilm formation (both strong and weak) strongly correlated with psla gene carriage. biofilm formation also correlated with mbl and ampc β-lactamase production. more importantly, multiple-β-lactamase phenotype was associated with formation of strong biofilms. results biofilm formation was observed in 43.5% of the isolates, of which 66.7% produced strong and 33.3% formed weak biofil...
