This study assessed the prevalence of colonization by Staphylococcus aureus in hospital housekeepers, and their knowledge and beliefs regarding this problem. Three saliva samples were collected and a questionnaire regarding knowledge and beliefs was applied. Of the 92 workers, 63 (68.5%) participated in the study; 20 were not and 43 were colonized; 13 by methicillin resistant Staphylococcus aur...
Abstract Background and Objective: Biofilm is a complex microbial community embedded in a self-produced extracellular polymeric matrix. We aimed to study the extent of biofilm formation by S. Areas isolates and its relation to some phenotypic and genotypic criteria. Material and Methods: One hundred-fifty strains of Staphylococcus aureus isolated from Gorgan were studied. Microtiter plate a...
appear to have subsequently acquired methicillin resistance through horizontal transfer of SCCmec type IV. The spa type of the Italian isolate comprises 7 nucleotide repeats, indicated by XJ4AKAOM in the alphabetical code. This repeat sequence differs from that of the classical SWP clone, indicated by XKAKAOMQ (8), by only 1 bp in the second repeat and loss of the last Q repeat. In spite of the...
بروز و گسترش مقاومت دارویی در میان عوامل میکروبی و همچنین عوارض جانبی داروهای شیمیایی باعث تلاش بیش از پیش دانشمندان برای یافتن داروهای جایگزین شده است. در این میان تحقیق و شناسایی خواص دارویی گیاهان جایگاه منحصر به فردی دارد. در این تحقیق اثر آنتی¬باکتریال عصاره تام و فراکسیون¬های اتردوپترولی، آبی و متانولی حاصل از بخش¬های هوایی گیاه cleome brachycarpa vahlex dc علیه 6 سوش باکتریایی که شامل: ...
OBJECTIVE To determine the effectiveness of simple control measures on the infection status and characteristics of methicillin-resistant Staphylococcus aureus including susceptibility patterns among health professionals and patients in a teaching hospital. METHODS The cross-sectional study was conducted from September 2013 to January 2014, and comprised samples collected from healthcare perso...
OBJECTIVES To analyse the possible relationship between consumption of old and new MRSA-active antibiotics and burden of MRSA in acute care hospitals in Catalonia during the period 2007-12. METHODS Fifty-four hospitals participating in the VINCat Programme were included. Proportion of MRSA (resistant isolates of Staphylococcus aureus per 100 isolates of S. aureus tested), incidence of new cas...
Detection of Methicillin Resistant Staphylococcus aureus (MRSA) by CHROMagar Versus Cefoxitin Disk Diffusion Method
Background and Objective: Efflux pumps are regarded as one of the most important mechanisms of antibiotic resistance in this era. Staphylococcus aureus is one of the bacterial groups with efflux pumps. The pumps’ activity is coded by specific genes. The aim of this study was to determine the phenotypic and molecular pattern of efflux pumps in the clinical isolates of methicillin-resistant...
the objective of this study was to determine the occurrence of antimicrobial resistance among staphylococcus aureus and to estimate the presence of methicillin-resistance in s. aureus (mrsa) isolates obtained by culture and polymerase chain reaction (pcr) methods. for this purposes, 100 iranian white and feta cheese samples collected from different suppliers were initially evaluated for the occ...
introduction: methicillin-resistant staphylococcus aureus (mrsa) can cause serious and life-threatening hospital- and community-acquired infections. colonized and infected patients represent the most important reservoir of mrsa in health care facilities. therefore, in this study, mrsa isolates collected from shohada hospital in tabriz were evaluated for the frequency of meca gene and their anti...
