PURPOSE An outbreak of gram-negative bacteremia in patients undergoing endoscopic retrograde cholangiopancreatography (ERCP) was investigated to determine the sources of infection and to control transmission. PATIENTS, METHODS, AND RESULTS The incidence of post-ERCP bacteremia increased from 1.6% (60 of 3,696) procedures to 3.6% (53 of 1,454) procedures(More)
OBJECTIVE To describe an outbreak of extended-spectrum beta-lactamase (ESBL)-producing Klebsiella pneumoniae in the intensive care units (ICUs) of a hospital and the impact of routine and reinforced infection control measures on interrupting nosocomial transmission. DESIGN Outbreak report. SETTING A 31-bed intensive care department (composed of 4 ICUs)(More)
The recognition of a cluster of antibiotic-associated nosocomial Clostridium difficile disease (NCDD) caused by serotype C in a surgical ward led to a hospital-wide NCDD surveillance and control program. The initial step included: (a) gas-liquid chromatography screening of inpatients' diarrheal stools; (b) enteric isolation precautions, cohorting and(More)
OBJECTIVES To describe the investigation and molecular characterization of a vancomycin-resistant Enterococcus faecium (VREF) strain responsible for a nosocomial outbreak in the haematology unit of a tertiary-care university hospital. PATIENTS AND METHODS Two patients admitted to the haematology unit developed infection/colonization with VREF over a 3(More)
To determine the source of a nosocomial outbreak of Legionella pneumophila serogroup 1 infection and the efficacy of control measures, clinical and environmental isolates were characterized by molecular subtyping and disease surveillance was conducted. The outbreak involved 32 cases (relative risk, 4.0; P less than .001 vs. previous period). Water(More)
Between January 1 and June 30, 1983, immunosuppressive drugs were administered in 20 renal transplant recipients undergoing 23 rejection episodes and in 3 patients with renal failure secondary to systemic disease. Legionella pneumophila, serogroup 1, pneumonia was diagnosed on 12/26 (47%) occasions. In an attempt to decrease this high rate, a program of(More)
An epidemic involving 10 patients who developed a urinary tract infection within a few days after cystometry and/or cystoscopy is reported. A pure culture ofSerratia liquefaciens was obtained from the fluid inside the disposable dome of the cystometer. The outbreak ceased when the dome was systematically changed after each examination as required.
The microbial contamination and antimicrobial effectiveness of seven topical disinfectants prepared at the hospital pharmacy were studied. These products were controlled throughout storage and use. The manufacturing routine investigated was able to deliver larger batch sizes and quality products that allowed increased storage time. The formulations chosen(More)
Molecular typing was used to investigate an outbreak of infection caused by multidrug-resistant Enterobacter aerogenes (MREA) susceptible only to gentamicin and imipenem in an intensive care unit (ICU). Over a 9-month period, ciprofloxacin-resistant E. aerogenes isolates were isolated from 34 patients, or 4.1% of ICU admissions, compared with a baseline(More)
