Background: Urinary tract infection (UTI) is one of the most prevalent infections in patients referred to hospitals. Escherichia coli (E. coli) is the leading cause of UTI. Emerging and spreading infection by aminoglycoside resistant isolates is a healthcare concern worldwide. The present study aimed to investigate the antibiotic resistance patterns and prevalence of aminoglycoside acetyltransf...
Objective(s): Acinetobacter pittii has become an emerging opportunistic noscomial pathogen worldwide with multi-drug resistance. In the present study, an A. pittii strain was isolated from bronchoalveolar lavage fluid sample harboring both OXA-58 and NDM-1carbapenemase producing genes. The mechanisms of carbapenem resistance of the A. pittii strain was investigated.Materials and Methods: Carbap...
background pseudomonas aeruginosa is one of the most important agents causing nosocomial infections worldwide. multidrug resistance of isolated bacteria from nosocomial infections makes it difficult and sometimes impossible to treat. objectives the aim of the present study was to investigate the antibiotic resistance and association between blaimp and blavim genes with resistance to meropenem a...
Background: Acinetobacter baumannii is a highly virulent bacterium. It causes opportunistic and nosocomial infections and is a threat to healthcare settings. It has also developed multidrug resistance (MDR) capacity. The nosocomial bacteria and antibiotic resistance are primordial and a significant public health concern. These bacteria and their threat can be prevented by reducing infected food...
Background and Objective: According to the high incidence of Klebsiella pneumoniae nosocomial infections in different wards of health care units and the emergence of high levels of antibiotic resistance, evaluating the frequency of multi-drug resistant strains and recognizing the virulence factors may help treat the related infections. Materials and Methods: In this descriptive cross-sectional...
Background: The use of testosterone enanthate has increased among athletes, especially in resistance disciplines. Considering the side effects of using testosterone enanthate, it seems necessary to find alternative methods. The present study compared the independent and interactive effects of resistance training, testosterone and palm pollen extract on mRNA expression of MFN2, FISS and DRP1 gen...
Target modification and reduced drug accumulation are the main resistance mechanisms against fluoroquinolone antibiotics in Pseudomonas aeruginosa. We performed a genotypic characterization of three major Mex multidrug efflux pumps (MexAB-OprM, MexXY-OprM and MexCD-OprJ) in ciprofloxacin resistant clinical isolates of P. aeruginosa, collected from Tehran, Iran this was followed by sequencin...
Background and Objective: Pseudomonas aeruginosa is an opportunistic pathogen and one of the most frequent pathogens in nosocomial infections. This bacterium shows high resistance to majority of antibiotics including â-lactams. The aim of this study was to investigate the pattern of antimicrobial resistance and evaluation of IMP, SPM and SIM Metallo- Beta- Lactamase producing Pseudomonas aerugi...
Background and Objective: Integrons play an essential role in disseminating drug resistance genes among bacteria. The aim of this study was to determine the prevalence of integrons, and Extended-Spectrum β-Lactamase (ESBL) genes in Escherichia coli (E. coli) isolates collected from patients with urinary tract infection (UTI) referred to teaching hospitals in Ardabil, Iran. Materials and Method...
Abstract Background and Objective: Resistance to antiretroviral agents is a significant concern in clinical management of HIV-infected individuals. Resistance is the result of mutations that develops in the viral protein targeted by antiretroviral agents. Material and Methods: In this cross-sectional study, the blood samples of 40 HIV-positive patients were collected. Twenty of them were d...
