title: A pseudoepidemic due to Salmonella typhimurium.
abstract: A pseudoepidemic due to Salmonella typhimurium occurred in the clinical microbiology laboratory of a university hospital and involved 10 patients. One patient received "unnecessary" antibiotics. Investigation of the events implicated a contaminated rubber pipette bulb. Such bulbs should be considered as a possible source of false-positive cultures.
