results the present study indicates that carbapenems and new cephalosporin antibiotics were practically ineffective against the extensive drug resistance (xdr) strains. colistin was observed to be more effective, although in seven cases resistance to colistin observed. ampc β-lactamase and mbl could be an important contributory factor for imipenem resistance among the isolates in our hospital. ...

CONTEXT Experts and policy makers have repeatedly called for universal screening at hospital admission to reduce nosocomial methicillin-resistant Staphylococcus aureus (MRSA) infection. OBJECTIVE To determine the effect of an early MRSA detection strategy on nosocomial MRSA infection rates in surgical patients. DESIGN, SETTING, AND PATIENTS Prospective, interventional cohort study conducted...

OBJECTIVE To assess factors associated with multi-drug resistant Acinetobacter baumannii (MDR-AB) nosocomial infection. MATERIAL AND METHOD This hospital-based case-control study was conducted in patients admitted to Siriraj Hospital, Bangkok, Thailand between January 1, 2005 and December 31, 2005. The study population consisted of 155 cases with MDR-AB nosocomial infection and 310 controls w...

BACKGROUND The antibiotic resistance of nosocomial organisms is rapidly increasing. The purpose of this study was to determine the frequency of bacterial agents isolated from patients with nosocomial infection. METHODS This study was performed in the different wards of teaching hospitals of Mazandaran University of Medical Sciences (northern Iran). The study population consists of the patient...

We describe the Centers for Disease Control and Prevention's National Nosocomial Infections Surveillance system. Elements of the system critical for successful reduction of nosocomial infection rates include voluntary participation and confidentiality; standard definitions and protocols; identification of populations at high risk; site-specific, risk- adjusted infection rates comparable across ...

BACKGROUND The rate of nosocomial infection appears to depend on whether it is calculated using the Center for Disease Control (CDC) or carrier state criteria. The objective of this study was to differentiate between primary endogenous (PE), secondary endogenous (SE) and exogenous (EX) infections, and to compare this classification with CDC criteria for nosocomial infections. METHODS Children...

nearly 15% to 25% of patients in general hospitals have a catheter at some timeduring their stay. up to 97% of nosocomial urinary tract infections (utis) are relatedto catheter. the type of bacteremia is usually polymicrobial which makes the treatmentmore difficult. previous studies showed an increase in mortality from bacteremia in thesepatients. the aim of the present study was to compare the...

objective to investigate association between nosocomial infection, blood products transfusion and microorganisms responsible in patients who hospitalized at icu (intensive care unit). patients and methods in this prospective study, 217 patients who were admitted to the icu of taleghani hospital between august 2010 and august 2011 were included. nosocomial infections were defined using the conta...

background and aims: acinetobacter baumannii is regarded as an important nosocomial pathogen around the world, especially in the intensive care unit that today seems to be resistant to the most antibiotics. therefore, this study aimed to trace classes 1, 2, and 3 integrin in the isolates resistant to acinetobacter baumannii. materials and methods: in this descriptive study, acinetobacter bauman...

BACKGROUND Infections in critical care unit are high, and they are serious hospital problems. Infections acquired during the hospital stay are generally called nosocomial infections, initially known as infections arising after 48 h of hospital admission. The mostfrequent nosocomial infections (urinary, respiratory, gastroenteritis and blood stream infection) were common in patients at hospital....
