Typhimurium) isolates from Norwegian patients in 1996\u20139 was studied by numerical analysis of pulsed-field gel electrophoresis (PFGE) profiles. Three subclusters (E5, F1 and G1) comprised 47% of the 102 sporadic isolates investigated and 45% of the domestically acquired isolates fell in subclusters E5 and F1. Distinct seasonal and geographic variations were evident for these strains which have been responsible for both local outbreaks (E5) and a national epidemic (F1) where salmonella-infected hedgehogs and birds constituted the suggested primary source of infection. Subcluster G1 was dominated by imported multi-resistant definitive type (DT) 104 isolates. All multi-resistant isolates contained integron-associated gene cassette-structures.
