Background and Objective: According to the high incidence of Klebsiella pneumoniae nosocomial infections in different wards of health care units and the emergence of high levels of antibiotic resistance, evaluating the frequency of multi-drug resistant strains and recognizing the virulence factors may help treat the related infections. Materials and Methods: In this descriptive cross-sectional...
Abstract Background and purpose: Staphylococcus aureus is one of the major causes of community and hospital-acquired infections. Aminoglycosides are potent bactericidal agents that are often used in combination with beta-lactam or glycopeptide in treatment of staphylococcal infections. The aim of this study was to investigate the prevalence of the aminoglycoside modifying enzyme aac(6΄)-Ie/aph(...
Introduction: Methicillin-resistant Staphylococcus aureus (MRSA) is an important pathogen that causes several nosocomial or community-acquired infections. Adhesion to surfaces and subsequent biofilm formation are the major phases of a staphylococcal infection. The aim of this study was to detect the presence of icaABCD genes in clinical isolates of MRSA. Methods: A total of 110 clinical Staphyl...
Background & Aims: Duo to clinical use of antibiotics, pseudomonas aeruginosa strains with multiple drugs resistance have significantly increased throughout the world. Betalactamase production is one of the Mechanisms involved in resistance to pseudomonas aeruginosa resulting in many problems in the treatment of infections caused by this bacterium. The aim of this study was molecular analysis o...
Background & Aims: One of the main causes of nosocomial infection is pseudomonas aeruginosa and carbapenems is one of the most important classes of antibiotics used in the treatment of infections caused by this bacteria. Metallo-beta-lactamase (MBL) production is one of the most important mechanisms of resistance to carbapenems and their increased prevalence is a serious threat to treatment of ...
conclusions according to the results, six strains were resistant to six or seven antibiotics and all strains were at least resistant to two antibiotics. however, for each of these resistant bacteria one bacteriophage was isolated from environmental samples, which showed the effectiveness of bacteriophages to remove clinically resistant e. coli strains. effective phages in vitro showed effective...
Background and Aim: Staphylococci are common pathogens of humans and livestock that able to produce a wide range of diseases. Staphylococcus epidermidis and Staphylococcus aureus are the important factors for biofilm production in patients. This study was designed to determine the ability of biofilm production and the resistance pattern of Staphylococcus epidermidis and Staphylococcus aur...
results two- to four-fold decrease in minimum inhibitory concentration (mic) and two-fold increase in accumulation were observed for etbr in the presence of cccp for 67% (8) of 12 mdr strains. with cccp, two- to four-fold decrease in mic and 1.4- to 1.8-fold increase in the accumulation of β-lactames, tet, cip and mtz were obtained for 42% (5) of the mdr strains. six, five and three of the 12 m...
It is not clear what factors determine divergent outcomes of infections caused by H. pylori . In the present study, the protein profiles of different strains of H. pylori, isolated from three groups of patients with ulcerative disease, non-ulcerative gastritis and cancer disease, were analyzed using 1DSDS-PAGE. The patterns of different H. pylori strains were highly divergent. About 30.76% (7 b...
