This study aims at molecular identification of Salmonella Infantis isolated from backyard chickens and the detection of their antibiotic resistance genes. A total of 46 Salmonella-suspected samples isolated from backyard chickens of northern Iran were collected. Serotyping was done by the traditional method and then confirmed by PCR. Antimicrobial susceptibility of the isolates against 13 antim...
Background and Objective: Tamoxifen is the most commonly used treatment for the patients with breast cancer called ER +, which prevents the expression of genes that are effective in the growth and proliferation of cancer cells by estrogen. Resistant to Tamoxifen is a major clinical problem in breast cancer treatment. In recent studies, the role of microRNAs in tamoxifen resistance has been rais...
septoria tritici blotch (stb), caused by the ascomycete fungus mycosphaerella graminicola (asexual stage: septoria tritici), is one of the most important foliar diseases of wheat. in this research, quantitative expression analysis of five candidate genes for the induction of resistance to stb (pr-1, bsi, msr, per, and ppi) was conducted in the wheat cultivars ‘seri 82’ (susceptible) and ‘fronta...
Background: Plasmid-mediated quinolone resistance, which complicates treatment, has been increasingly identified in Escherichia coli isolates worldwide. The purpose of this study was to investigate the frequency of plasmid-mediated qnrA, qnrB, and qnrS genes among quinolones resistant E.coli isolated from Kerman hospitals, Iran. Methods: In the current study, 80 E. coli isolates...
conclusions this study demonstrated the co-existence of rmtc and blandm-1 genes for the first time in turkey. the spread of this resistant type should be monitored and limited through molecular surveillance. results twenty k. pneumoniae strains showed resistance to amikacin, and 40 were resistant to gentamicin. the mic value was found to be > 512 µg/ml in five amikacin-resistant strains and > 1...
Background: This study aimed to investigate the occurrence of aminoglycoside resistance and the prevalence of the resistance-modifying enzyme genes, ant(3”)-III, ant(6’)-Ia, aac(6′)-Ie-aph(2”)-Ia, and aph(2’)-Id, in Enterococcus strains isolated in Kermanshah Province, west of Iran.Methods: In this cross-sectional study, 108 enterococcal isolates from urine, wound, blood, and cerebrospinal flui...
Background and aim: Antimicrobial resistance is a worldwide problem causing health threats. Escherichia coli is one of the most important bacteria that causes resistance problems. The aim of this study was to evaluate the frequency of Escherichia coli, a extended spectrum beta-lactamase producing CTX-M and SHV, in hospital and non-hospital clinical specimens in Isfahan. Methods: In this stu...
Background: Acinetobacter baumannii, is an opportunistic pathogen and is responsible for numerous nosocomial infections. In recent years, this microorganism has been resistant to a wide range of antibiotics. One of the most important mechanisms of resistance in this microorganism is production of metallo-beta-lactamases (MBLs). Objectives: The aim of this study was to detect VIM- and IMP-type ...
conclusions the results illustrated the diversity of antibacterial resistance and virulence gene profiles among different sccmec types of s. aureus. the increased prevalence of methicillin-resistant s. aureus isolates containing different toxin and antibiotic resistance genes is a serious threat for the hospitalized patients in the intensive care units. methods in this cross-sectional study tha...
results two bacterial types, st208, and st218, were identified in all 140 samples. the st208 mainly came from icu and department of respiratory medicine, while st218 from department of plastic surgery; 70.21% of st208 and 84.78% of st218 were carbapenem-resistant acinetobacter baumannii (crab) and carbapenem-susceptible acinetobacter baumannii (csab), respectively. multidrug-resistance genes in...
