Epidemiologic typing of Salmonella enterica serotype enteritidis in a Canada-wide outbreak of gastroenteritis due to contaminated cheese.

Molecular and epidemiologic analysis of a county-wide outbreak caused by Salmonella enterica subsp. enterica serovar Enteritidis traced to a bakery

BACKGROUND An increase in the number of attendees due to acute gastroenteritis and fever was noted at one hospital emergency room in Taiwan over a seven-day period from July to August, 2001. Molecular and epidemiological surveys were performed to trace the possible source of infection. METHODS An epidemiological investigation was undertaken to determine the cause of the outbreak. Stool and bl...

An outbreak of gastroenteritis caused by Salmonella enterica serotype Enteritidis traced to cream cakes.

INTRODUCTION This paper describes the epidemiological, microbiological and environmental investigations conducted during an outbreak of Salmonella gastroenteritis in Singapore. METHODS A case-control study was undertaken to identify the vehicle of transmission. Microbiological testing was performed on faecal, food and environmental samples. Isolates of Salmonella were further characterized by...

New Options for Rapid Typing of Salmonella enterica Serovars for Outbreak Investigation

A number of different serovars of Salmonella enterica are often implicated in human nontyphoidal outbreaks. Globally, serovars Typhimurium and Enteritidis are often the causative agent of such outbreaks, but other serovars can also be significant (Table 1). Some serovars such as Infantis and Virchow are routinely linked to outbreaks of gastroenteritis. The consumption of raw food products or po...

Comparison of multiple-locus variable-number tandem repeat analysis, pulsed-field gel electrophoresis, and phage typing for subtype analysis of Salmonella enterica serotype Enteritidis.

Strain subtyping is an important tool for detection of outbreaks caused by Salmonella enterica serotype Enteritidis. Current subtyping methods, however, yield less than optimal subtype discrimination. In this study, we describe the development and evaluation of a multiple-locus variable-number tandem repeat analysis (MLVA) method for subtyping Salmonella serotype Enteritidis. The discrimination...
