Clonal circulation of Salmonella enterica serotype Heidelberg in Italy?

Euro Surveill. 2003 Nov;8(11):222-5. doi: 10.2807/esm.08.11.00434-en.

Abstract

Phenotypic and genetic characteristics of 21 strains of Salmonella serotype Heidelberg isolated in the years 1999-2003 from different sources in Italy were studied. Susceptibility patterns, plasmid analysis, and PFGE were used as epidemiological markers. Although non-homogeneous drug resistance patterns and plasmid profiles had been detected, PFGE patterns suggest the hypothesis of a nationwide clonal spread of this serotype associated with poultry.
