[Show abstract][Hide abstract] ABSTRACT: To determine the source of an outbreak of Salmonella javiana infection.
A total of 101 culture-confirmed cases and 540 epidemiologically linked cases were detected between May 26, 2003, and June 16, 2003, in hospital employees, patients, and visitors. Asymptomatic employees who had eaten in the hospital cafeteria between May 30 and June 4, 2003, and had had no gastroenteritis symptoms after May 1, 2003, were chosen as control subjects.
A 235-bed academic tertiary care children's hospital.
Isolates from 100 of 101 culture-confirmed cases had identical pulsed-field gel electrophoresis patterns. A foodhandler with symptoms of gastroenteritis was the presumed index subject. In multivariate analysis, case subjects were more likely than control subjects to have consumed items from the salad bar (adjusted odds ratio [aOR], 5.3; 95% confidence interval [CI], 2.3-12.1) and to have eaten in the cafeteria on May 28 (aOR, 9.4; 95% CI, 1.8-49.5), May 30 (aOR, 3.6; 95% CI, 1.0-12.7), and/or June 3 (aOR, 4.0; 95% CI, 1.4-11.3).
Foodhandlers who worked while they had symptoms of gastroenteritis likely contributed to the propagation of the outbreak. This large outbreak was rapidly controlled through the use of an incident command center.

[Show abstract][Hide abstract] ABSTRACT: We compared three automated microbiology systems: MicroScan Walk-Away ® (DADE BEHRING INC., West Sacramento, CA), Phoenix ™ [P] (Becton Dickinson Diagnostic Systems, Sparks, MD) and VITEK·TWO ® [V] (bioMérieux, Durham, NC). Two different panels were used with the MicroScan system: Rapid [MR] and conventional [MC]. Organisms tested included clinical isolates from cultures obtained from a variety of body sites from patients at SLCH and a subset of challenge organisms.
