Investigation of phenotypic resistance pattern of Enterococcus faecalis isolated from blood and urine samples of patients admitted to Rasoul Akram Hospital
Authors
Abstract:
Background: Nosocomial infections can be a major challenge for medical staff and health care providers when it comes to antibiotic-resistant bacteria. Enterococcus faecalis is one of the bacteria that plays an important role in nosocomial infection. Therefore, it is important to study the prevalence and pattern of resistance of this bacterium in medical centers, especially in hospitals. The aim of this study was study of phenotypic resistance pattern of Enterococcus faecalis isolated from blood and urine samples of patients admitted to Rasoul Akram Hospital Method: This cross-sectional study was performed from February 1997 to January 1998 at Rasoul Akram Hospital in Tehran. The origin of the isolated Enterococcus faecalis was urine and blood which were isolated from patients with urinary tract infections and bloodstream infections from the hospital. Antibiogram test was performed using disc diffusion method and E-test to measure the resistance of these isolates. Result: From 53 isolated Enterococcus faecalis, 46 samples (86.8%) were isolated from the urine and 7 samples (13.2%) were isolated from the blood. The most sensitive antibiotics for these isolates were Linzuide (52), 98.1%, Vancomycin (47), 88.7%, respectively and the most resistant antibiotics to these isolates were Gentamicin antibiotic (43), 81.1%, and rifampin (34), 64.2%. Conclution: The resistance of Enterococcus faecalis to antibiotics is increasing. Therefore, periodic monitoring of the resistance pattern of this bacterium can help effectively treatment of patients and reduce treatment costs.

Introduction: Urinary tract infection (UTI) is one of the most common infections and Enterobacteriaceae members are the most common bacterial agent of this infection. Antibiotic susceptibility pattern identification is necessary for complete treatment. In this way, this study was accomplished to compare the enterobacteriaceae antibiotic resistance pattern of UTI patients. Materials and Methods:...

Background and Objective: Urinary tract infection is the second most common cause of infection in the human body. Among the causes of urinary tract infection, Escherichia coli is the most common bacteria causing the urinary tract infection in both genders (male and female). Therefore, the aim of this study was to determine the antibiotic resistance pattern of bacteria causing urinary tract infe...

Background: Infections are one of the most important causes of death in infants, especially in developing countries. Inappropriate use and administration of antibiotics can contribute to the resistance and spread of infection. In this study, we determined the antibiotic resistance pattern of the bacteria isolated from clinical samples of blood, cerebrospinal fluid, and urine in the neonatal int...

Haemolysin, enterococcal surface protein (Esp), aggregation substance and gelatinase are some markers that have been proposed as possible enterococci virulence factors. The aim of this study was to detect the presence of haemolysin, gelatinase and enterococcal surface protein in enterococci isolated from urine and to determine their susceptibility to antimicrobial agents. A total of 50 strains ...
