background: human exposure to antibiotic resistant bacteria (arb) is a public health concern which could occur in a number of ways. wastewaters seem to play an important role in the dissemination of bacteria and antibiotic resistant genes (args) in our environment. the aim of this study was to evaluate the occurrence of three groups of arb and their resistance genes in hospital and municipal wa...
background mercury is one of the most toxic heavy metals. even a small amount of it is toxic for all living organisms. some of bacteria have developed special resistance mechanisms against mercury, in addition to resistant to different antibiotics. these bacteria usually acquire hg and antibiotic resistance genes via horizontal gene transfer in their habitat. objectives the aim of this study wa...
BACKGROUND The incidence of bacteremia caused by Gram-negative bacteria has increased recently in febrile neutropenic patients with the increase of antibiotic-resistant Gram-negative bacterial infections. This study aimed to identify the distribution of causative bacteria and the proportion of antibiotic-resistant bacteria in bacteremia diagnosed in febrile neutropenic children. MATERIALS AND...
6 The large reservoir of antibiotic resistant bacteria in raw and treated water supplies is a matter of public health concern. Currently, the National Antimicrobial Resistance Monitoring Systems, a collaborative effort of the Centers for Disease Control, the US Department of Agriculture, and the US Food and Drug Administration, does not monitor antimicrobial resistance in surface waters. Given ...
Background: Multidrug-resistant (MDR) enterococci cause many problems for physicians and infection control specialists in the recent years. Hence, by the identification of antibiotic resistance patterns of enterococci in different geographical regions an appropriate strategy can be developed to prevent bacterial antibiotic resistance and provide effective treatment. The current study aimed at i...
Objective: Burn wound infection is a severe complication of thermal injury. Patients with severe burn injuries need urgent care to diminish complications after severe burns. Wound infections are commonly considered one of the most serious burn complications, particularly those that are caused by extensively drug-resistant (XDR) bacteria with few therapeutic choices. The objective of this study ...
Abstract Background and objective: The periodic evaluation of antimicrobial activity of different antibiotic is essential because antibiotic sensitivity pattern may also changed during short courses. The aim of this study was to assess the frequency of Multi-drug Resistance (MDR) in Gram negative uropathogens. Material and Methods: This study was conducted on 111 gram negative uropatho...
arsenic is one of the most dangerous heavy metals in the environment that is harmful for organisms such as human beings. due to this treat economic approach for elimination of arsenic from water and wastewater is necessary. in this research arsenic-resistant bacteria from water and sediments of lake maharloo were isolated and identified then their antibiotic resistance was evaluated. sampling w...
Background & Aims : Cefepime is one of the fourth generations of cephalosporins known to be active against a wide range of bacteria. Cefepime is usually used for treatment of infections caused by multi-drug resistant bacteria. The aim of this study was the evaluation of the effect of this antibiotic on clinical E.coli isolates. Materials & Methods : A total of 100 isolates of E.coli were ...
Background and purpose: Wastewaters are the most important sources of antibiotics entrance into the aqueous environments. Conventional wastewater treatments cannot eliminate these micropollutants and antibiotic resistant bacteria. The aim of this study was to determine the antibiotic resistance pattern in bacteria isolated from untreated sewage and effluent of municipal wastewater treatment pla...
