چکیده
OBJECTIVE Identify a source of contamination to explain the increase in the number of cases of S. Paratyphi B var. Java infection. METHOD A descriptive study was conducted to gather more information about cases and potential risk factors for infection. Between January 2000 and June 2003, we identified and interviewed by questionnaire 53 people with S. Paratyphi B infection. Due to the suspected link with fish tanks, an environmental investigation was conducted for each case at patients' homes as well as at pet stores and wholesalers. Various samples were taken from fish tanks. The fish were purchased at different pet shops. The pulsed field gel electrophoresis method was used to compare the human and aquarium strains. RESULTS Of those infected, 60% had bought or had contact with an aquarium or tropical fishes before becoming ill. More than 50% of the samples taken from fish tanks in homes, pet shops, and wholesaler operations contained a number of serotypes of Salmonella in addition to Salmonella Paratyphi B var. Java. There were similarities between the PFGE patterns of human strains and aquarium samples. DISCUSSION Contact with fish tanks could be a risk factor for developing a Salmonella infection and the public may be unaware of this risk. It was recommended that information be produced and distributed to pet shops and their customers to inform them of safety precautions in order to reduce the risk of contamination from bacterial pathogens that may be present in aquarium water.

Multistate outbreak of human Salmonella infections associated with exposure to turtles--United States, 2007-2008.
Turtles and other reptiles have long been recognized as a source of human Salmonella infections. To prevent turtle-associated Salmonella infections in humans, the sale and distribution of small turtles (i.e., those with a carapace length of less than 4 inches) has been prohibited in the United States since 1975. Despite this prohibition, small turtles remain available to the public from various...

Multidrug-resistant Salmonella enterica serovar Paratyphi B dT+ isolates from patients with gastroenteritis were identical with isolates from their home aquariums. Matched isolates had identical phage types, XbaI and IS200 profiles, and Salmonella genomic island 1 (SGI1). Ornamental fish tanks are reservoirs for SGI1-containing S. Paratyphi B dT+.
