Limited genetic diversity in Salmonella enterica Serovar Enteritidis PT13

BMC Microbiology

Table 1 Sequence-based typing of Salmonella enterica serovar Enteritidis. The number of polymorphic sites, in reference to PT13 isolate 05-6733, are indicated for each examined locus. The number of base pairs analyzed for each locus is indicated in brackets. Strains were isolated in 2004, 2005 or 2006, and these dates correspond to the first two digits in the strain identification number. BC, British Columbia; NS, Nova Scotia; ON, Ontario; QC, Québec

a. Plasmid profile as determined by digestion of plasmid DNA with restriction enzyme Bgl II; 0 = strains did not possess large plasmid and had no DNA fragments when digested with Bgl II
b. Individual polymorphisms are in addition to insertions and deletions, in reference to PT13 isolate 05-6733.
