Distribution of 84 single-nucleotide polymorphisms (SNP) markers and their phylogenetic relationships. a Nucleotide diversity of the 84 SNP markers ranged from 0.011 to 0.107 (mean = 0.049 ± 0.018, median = 0.044). b The 84 SNP markers were able to type 176 Salmonella Tennessee strains, showing 100% typeability. The phylogenetic relationships of the 176 S. Tennessee strains were generated using the unweighted pair group method with arithmetic mean (UPGMA), which identified four clades and nine subtypes. *Outbreak association: yes; illness onset or isolation of S. Tennessee during 2006.08.01 to 2007.07.31, no; illness onset or isolation of S. Tennessee before 2006.08.01 or after 2007.07.31, suspect: strains that were isolated during 2006.08.01 to 2007.07.31 with unknown PFGE results or with PFGE profiles of JNXX01.0010, JNXX01.0011, or JNXX01.0026 with an unknown date of isolation or illness onset. Numbers in parenthesis indicate the number of isolates. NA: PFGE profile not available
