BACKGROUND Many case series studies have reported risk factors of infection with anaerobic bacteria, but few factor analysis studies have been conducted. OBJECTIVE We conducted a case-control study to identify the risk factors of anaerobic bacteremia. METHODS We compared a number of characteristics of patients with anaerobic bacteremia with those with aerobic bacteremia. Clinical informatio...

Bacteremia, the presence of viable bacteria in the blood stream, is often associated with several clinical conditions. Bacteremia can lead to multiple organ failure if managed incorrectly, which makes providing suitable nutritional support vital for reducing bacteremia-associated mortality. In order to provide such information, we investigated the metabolic consequences of a Klebsiella pneumoni...

TO THE EDITOR— We thank Nannini and Arias for their interest in our article [1]. They raise several important issues in assessing the impact of emergency department occult Staphylococcus aureus bacteremia on patient outcomes [2]. Although 30-day mortality is a commonly used study endpoint in most bacteremia outcome researches, we agree that a 30-day follow-up period might be inadequate for pati...

The epidemiology of bacteremia developing during neutropenia has changed in the past decade, with the re-emergence of Gram-negative (GN) bacteria and the development of multidrug resistance (MDR) among GN bacteria. We conducted a case-control study in order to identify factors associated with bacteremia due to multidrug-resistant Gram-negative (MDRGN) isolates in hematopoietic stem cell transpl...

BACKGROUND Although Escherichia coli is a well-recognized cause of urinary tract infection in seniors, little is known about the burden of invasive E. coli infection in this population. METHODS We conducted a population-based cohort study of 46,238 noninstitutionalized Group Health Cooperative members>or=65 years of age to ascertain incidences of community-onset E. coli bacteremia and, for co...

Escherichia coli K1 strains, isolated from human newborns with meningitis, were fed to pathogen-free Sprague-Dawley infant rats by an oral gastric tube. Feeding of 10(3) to 10(11) organisms colonized the intestine of approximately 70% of the animals. At 5 days postfeeding of 3- to 5-day-old rats, bacteremia was detected in 60%, and meningitis occurred in 15% of bacteremic animals. Colonization ...

INTRODUCTION Our objective was to assess the cost implications of a vertical MRSA prevention program that led to a reduction in MRSA bacteremia. METHODS We performed a matched historical cohort study and cost analysis in a single hospital in Israel for the years 2005-2011. The cost of MRSA bacteremia was calculated as total hospital cost for patients admitted with bacteremia and for patients ...

INTRODUCTION Staphylococcus aureus is the cause of 11-33% of nosocomial bloodstream infections and has a complication rate close to 50%. S. aureus accounts for 31% of isolates in the Instituto Nacional de Cancerología (INC), in Bogotá, Colombia, and is the main etiological agent of bacteremia. This study describes the risk factors for mortality caused by S. aureus bacteremia in cancer patients....

BACKGROUND Information is sparse regarding the association between international travel and hospitalization with non-typhoidal Salmonella bacteremia. The aim of this study was to determine the proportion, risk factors and outcomes of travel-related non-typhoidal Salmonella bacteremia. METHODS We conducted a 10-year population-based cohort study of all patients hospitalized with non-typhoidal ...

The aim of the investigation was to describe the incidence of Aeromonas bacteremia in a city with a population of about 1.87 million inhabitants, located in southern Taiwan, between 2008 and 2010. Such data were compared with the incidences of Vibrio and Salmonella bacteremia in the same period and the incidence of Aeromonas bacteremia in other countries in the literature. The data revealed the...
