A prospective study was initiated in an intensive care unit (ICU) where extended-spectrum beta-lactamase-producing enterobacteriaceae (ESBLPE) were endemic. From July 1990 to July 1991, patients hospitalized for > or = 5 days were screened for ESBLPE acquisition by means of weekly rectal sampling and clinical cultures. Baseline characteristics and various ICU procedures in 62 cases of ESBLPE we...

BACKGROUND Increasing numbers of infections following transrectal prostate biopsy (TPB) at our hospital led us to investigate clinical and bacterial risk factors to determine if the colonizing rectal Escherichia coli population is the source. METHODS We performed an observational cohort study of men undergoing TPB (1 January 2010-6 February 2014) at the San Diego Veterans Affairs Medical Cent...

Objectives: Early detection of vancomycin resistant enterococci (VRE) colonization in hospitalized patients plays an important role in controlling enterococcal infections. For this purpose, the detection of VRE from rectal swab specimens can be performed with various methods. Methods: In this study, VRE colonization in the rectal swab samples of patients from intensive care units, burn unit, an...

A virulent European Escherichia coli O157:H- isolate is nonmotile due to a 12-bp deletion in the flagellar regulatory gene flhC. To investigate the contribution of flhC in the relationship between E. coli O157:H7 and cattle, we constructed a similar flhC regulatory mutant in the well-characterized strain ATCC 43894. There was no difference in the growth rate between the wild type and this regul...

Rectal swabs obtained from 10 of 49 chronic-care geriatric patients were positive for Clostridium difficile, for a prevalence rate of 20.4%. Simultaneous sampling of 29 patients in an acute geriatric ward revealed four colonized patients, for a prevalence rate of 13.7%. A prospective study of C. difficile colonization in 100 consecutive patients admitted to an acute geriatric ward was carried o...

BACKGROUND Serratia marcescens represents an important pathogen involved in hospital acquired infections. Outbreaks are frequently reported and are difficult to eradicate. The aim of this study is to describe an outbreak of Serratia marcescens occurred from May to November 2012 in a neonatal intensive care unit, to discuss the control measures adopted, addressing the role of molecular biology i...

Abstract Objectives: We aimed to compare classical methods and chromogenic media detect carbapenem-resistant Enterobacteriaceae (CRE) colonization among hospitalized patients determine the risk factors causing infection in colonized patients. Methods: Between January August 2017, 100 over age of 18 who were Reanimation Intensive Care Unit Trauma Emergency a university hospital examined. From fi...

We conducted a cross-sectional study to determine the prevalence of, and risk factors for, colonization with fluoroquinolone (FQ)-resistant Escherichia coli in residents in a long-term care facility. FQ-resistant E. coli were identified from rectal swabs for 25 (51%) of 49 participants at study entry. On multivariable analyses, prior FQ use was the only independent risk factor for FQ-resistant ...
