[Retrospective study on the isolated strains of Salmonella in an Iranian hospital in Kermanshah]

Abstract

A survey of occurrence of Salmonella in blood and bone marrow cultures was conducted in 1989- 1990 and 1999- 2000 [‎Sina hospital, Kermanshah]‎. A total of 496 [‎12.3%]‎ and 60 [‎2.4%]‎ Salmonella strains were isolated [‎from 4020 and 2447 cultures]‎. In 1989- 1990, the isolated strains were: S. typhi 448 [‎98.5%]‎, S. paratyphi A 40 [‎8%]‎, S. paratyphi B 5 [‎1%]‎ and S. paratyphi C 3 [‎0.5%]‎. In 1999- 2000, the isolated strains were S. typhi 59 [‎98%]‎ and S. paratyphi B 1 [‎1.5%]‎. There was a 60.9% reduction in the number of specimens over the 2 periods. The rate of Salmonella isolation fell from 12.3% [‎1989- 1990]‎ to 2.4% [‎1999- 2000]‎. There was a 10.2, 8.3 and 6.6 times increase in resistance of S. typhi strains to ampicillin, chloramphenicol and trimethoprim- sulfamethoxazole respectively
