The data obtained in the present study indicate that the regular consumption of PJ can prevent NAFLD even in the presence of the other risk factors such as obesity, hypercholesterolemia, and high energy, fat and sugar intakes. © 2016 Society of Chemical Industry.
Background and Objectives. The aim of this study was to determine the frequency of bla NDM, bla PER, bla VEB, bla IMP, and bla VIM type genes among A. baumannii isolates from hospitalized patients in two hospitals in Tehran, Iran. Patients and Methods. Antibiotic susceptibility tests were performed by Kirby-Bauer disc diffusion and Broth microdilution methods. The frequency of MBL (metallo-beta-lactamase) and ESBL (extended-spectrum-beta-lactamase) producers was evaluated by CDDT. The β -lactamases genes were detected by PCR and sequencing methods. Results. The resistance of A. baumannii isolates against tested antibiotics was as follows: 103 (95.4%) to ceftazidime, 108 (100%) to cefotaxime, 105 (95.7%) to cefepime, 99 (91.7%) to imipenem, 99 (91.7%) to meropenem, 87 (80.6%) to amikacin, 105 (97.2%) to piperacillin, 100 (92.6%) to ciprofloxacin, 103 (95.4%) to piperacillin/tazobactam, 44 (40.7%) to gentamicin, 106 (98.1%) to ampicillin/sulbactam, 106 (98.1%) to co-trimoxazole, 87 (80.6%) to tetracycline, and 1 (1.8%) to colistin. Using combined disk diffusion test, 91 (84.2%) and 86 (86.86%) were ESBL and MBL producers, respectively. The prevalence of bla PER-1, bla VEB-1, bla IMP-1, and bla VIM-1 genes was 71 (78.03%), 36 (39.5%), 3 (3.48%), and 15 (17.44%), respectively. Conclusions. The prevalence of ESBLs and MBLs-producing A. baumannii strains detected in this study is a major concern and highlights the need of infection control measures.
Background: Metallo-beta-lactamase (MBL)-producing Acinetobacter baumannii is a growing therapeutic concern, worldwide. Objectives: The aim of this study was to determine the frequency of SPM and IMP type genes among A. baumannii isolates from hospitalized patients in Loghman Hakim and Milad hospitals, Tehran-Iran from 2012 to 2013. Patients and Methods: This study was conducted on 108 A. baumannii isolates collected from two hospitals in Tehran, Iran. Antibiotic susceptibility tests were performed by Kirby-Bauer disc diffusion and Broth microdilution methods according to clinical laboratory standards institute (CLSI) guidelines, and combined disk diffusion test (CDDT) was performed for identification of metallo-beta-lactamases (MBLs). The blaIMP and blaSPM genes were detected by PCR and sequencing methods. Results: The resistance of A. baumannii isolates against tested antibiotics were as follow: 108 (100%) to cefotaxime, 103 (95.4%) to ceftazidime, 99 (91.7%) to meropenem, 99 (91.7%) to imipenem, 44 (40.7%) to gentamicin, 87 (80.6%) to amikacin, 100 (92.6%) to ciprofloxacin, 105 (95.7%) to cefepime, 105 (97.2%) to piperacillin, 103 (95.4%) to piperacillin/tazobactam, 106 (98.1%) to ampicillin/ sulbactam, 106 (98.1%) to co-trimoxazole, 87 (80.6%) to tetracycline and 1 (1.8%) to colistin. Using combined disk diffusion test, it was found that out of 99 imipenem non-susceptible A. baumannii strains, 86 (86.86%) were MBL producers. The prevalence of IMP-1 gene among metallo-beta-lactamase-producing A. baumannii isolates was 3 of 86 (3.48%). Conclusions: The prevalence of metallo-beta-lactamase-producing A. baumannii strains detected in this study is of great concern and highlights the need of infection control measures including antibacterial management and prompt identification of betalactamase-producing isolates.
Background: Emerging antibacterial resistance rates and extended-spectrum-β-lactamase producing Escherichia coli recovered from urinary tract infections (UTI) is an increasing problem in different regions, limiting therapeutic options. Objectives: The aim of this study was the detection of bla TEM , bla SHV and bla CTX-M genes among Escherichia coli strains causing Urinary Tract Infection in children from Iran. Materials and Methods: A total of 100 Escherichia coli isolates were collected from urine specimens of patients with UTI who had referred to the Children Medical Center, Tehran, Iran between November 2012 and July 2013. Antibiotic susceptibility test was performed by Kirby-Bauer disc diffusion method according to CLSI guidelines. The bla CTX-M , bla TEM and bla SHV genes were detected by PCR and sequencing methods. Results: The resistance rate of isolates to cefotaxime, ceftazidime, imipenem, gentamicin, amikacin, cefepime, piperacillin/tazobactam, co-trimoxazole, nitrofurantoin, cefixime and cephalothin, were 51 (51%), 24 (24%), 0 (0%), 25 (25%), 2 (2%), 6 (6%), 2 (2%), 79 (79%), 7 (7%), 36 (36%) and 43 (43%), respectively. In this study, imipenem was more active than other antibiotics. The existence of bla TEM-1 and bla CTX-M-15 was detected in 69 (69%) and 74 (74%) isolates respectively, while bla SHV gene was not detected. Conclusions: The prevalence of β-lactamase-producing genes in E. coli detected by this study is of great concern and highlights the need of infection control measures including antibacterial management and prompt identification of isolates with beta-lactamase-producing genes.
