Phylogenetic analysis of XbaI–pulsed-field gel electrophoresis (PFGE) profiles obtained among a subset of 40 selected nonmotile Salmonella enterica serotype 1,4,[5],12:–:– strains isolated from humans and nonhumans during 2001–2009, France. Multilocus variable number tandem repeat analysis (MLVA), strain code, antimicrobial susceptibility testing (AST), PFGE profile found in our PFGE Typhimurium database, antigenic formula (serotype), and source and year of isolation are indicated to the right o

Figure A1. Phylogenetic analysis of XbaI–pulsed-field gel electrophoresis (PFGE) profiles obtained among a subset of 40 selected nonmotile Salmonella enterica serotype 1,4,[5],12:–:– strains isolated from humans and nonhumans during 2001–2009, France. Multilocus variable number tandem repeat analysis (MLVA), strain code, antimicrobial susceptibility testing (AST), PFGE profile found in our PFGE Typhimurium database, antigenic formula (serotype), and source and year of isolation are indicated to the right of the PFGE profiles. The MLVA groups indicated in the rectangles are the strains with the MLVA type found in our food poisoning investigation with its single- and double-locus variant with 1 repetition difference. P1 indicates the egg producer implicated in the tiramisu food poisoning. A, amoxicillin; S, streptomycin; Sp, spectinomycin; C, chloramphenicol; Su, sulfonamide; Te, tetracycline; Tmp, trimethoprim; Na, nalidixic acid. *Auto sampling; †authority sampling I; ‡tiramisu consumption; §authority sampling II.
