Sigrún Gudmundsdóttir, Hjördís Harðardóttir, Eggert Gunnarsson

Abstract

A total of 75 Salmonella enterica serovar Typhimurium strains of various (mainly human and animal) origins were typed by pulsed-field gel electrophoresis (PFGE) and phage typing. These strains were collected during an outbreak in Iceland in 1999 and 2000. The typing revealed that 84% of the strains belonged to the same PFGE and phage type (PT), namely, PFGE type 1Aa and PT 1.
