Biotic Relationships: Distribution of Antibiotic Resistance Genes in Nosocomial Pathogens
The strong selective pressure exerted by excessive use of antibiotics in the last decades has increased the acquisition of resistance genes by horizontal gene transfer. Horizontal gene transfer contributed to the diversification of microorganisms by influencing traits such as metabolic potential of a bacterial cell, antibiotic resistance, symbiosis, fitness, and adaptation. The study of biotic ...
متن کاملThe Impact of a Nationwide Antibiotic Restriction Program on Antibiotic Usage and Resistance against Nosocomial Pathogens in Turkey
PURPOSE Antimicrobial resistance among microorganisms is a global concern. In 2003, a nationwide antibiotic restriction program (NARP) was released in Turkey. In this study we evaluated the effect of NARP on antibiotic consumption, antimicrobial resistance, and cost. MATERIALS AND METHODS The data obtained from all of the four university hospitals, and one referral tertiary-care educational s...
متن کاملEpidemiological study of nosocomial infections and antibiotic resistance patterns In Guilan
Background: Nosocomial infections are the most important challenge in the health system, due to the mortality and economic costs. The aim of this study was to evaluate the epidemiology of nosocomial infections and determine antibiotic resistance patterns. Materials and Methods: This retrospective descriptive study was carried out on the medical records of 738 patients hospitalized in Poursina ...
متن کاملBacterial isolation and antibiotic resistance of nosocomial pneumonia in hospitalaized patients - Kashan, Iran
Introduction: Bacterial pneumonia occurs in most hospitalized patients where is the important cause of morbidity and mortality. To reduce the mortality rate, we aimed to isolate the bacterial agents of pneumonia and determine the antibacterial resistance. Methods: In this descriptive study, 330 hospitalized patients inffered from bacterial pneumonia were studied to identify the bacterial ag...
متن کاملModeling the Spread of Antibiotic Resistance
This paper describes a stochastic implementation of Austin et al.’s (1999) model of the spread of antibiotic resistance in a population of fixed size under varying conditions of antibiotic use. The population is divided into sub-groups: individuals colonized by commensal bacteria and an uncolonized group. The colonized group is further divided according to whether the commensal bacteria are sen...
