b a ckground: cockroaches are among the medically important pests found within the human habitations that cause serious public health problems. they may harbor a number of pathogenic bacteria on the external surface with anti- biotic resistance. hence, they are regarded as major microbial vectors. this study investigates the prevalence and antibiotic resistance of gram-negative pathogenic bacte...
background the rapid emergence of antibiotic resistance, especially broad-spectrum antibiotics, resulted in the avid use of new potent antibiotics. ceftriaxone and ceftazidime, two third-generation cephalosporin, are usually used to manage complicated and uncomplicated infections. the use of cefepime in resistant infections is increasing gradually, which put this potent antibiotic at risk of re...
conclusion although all esbl producer gram-negative bacteria were sensitive to imipenem, piperacillin-tazobactam, and colistin, non-esbl isolates showed resistant pattern. interestingly, notable percent of mentioned resistant isolates were sensitive to nitrofurantoin. background resistance in enteric gram-negative bacteria is of a great concern and concise local data are lacking. objectives to ...
Background and Objectives: Non-fementer gram-negative bacilli (NFGB) are ubiquitous pathogen that has emerged as a major cause of health care associated infections. The aim of this study was to determine the prevalence and antimicrobial susceptibility of NFGB in an Iranian hospital. Materials and Methods: FromJuly 2005 to November 2006 a total of 257 strains of NFGB including 109 (42.41%)...
Abstract Background and Objective: The excessive use of broad-spectrum antibiotics will lead to drug resistance of microorganism and specially nosocomial organisms. Because of high incidence of antibiotic resistance in hospitals, we aimed to study antibiotic resistance to gram negative bacteria. Material and Methods: This cross-sectional study was conducted on the data of biological sampl...
Introduction: Antibiotic resistance survey in Gram-negative bacteria has an important role in the management of treatment. The aim of this study was to evaluate antibiotic resistance of Gram-negative bacteria isolated from patients and determination of contamination rate of different wards of hospital to these bacteria. Methods: Information of 3242 patients from hospital information system o...
