List of Salmonella isolates and summary of tests applied to each invA positive sample.
Table 6.

Fig 3.
XbaI PFGE patterns for the serotyped Salmonella isolates (n = 21) collected from the six agricultural ponds in Central Florida during the two-year survey.
Band sizes (kb) are displayed at the top of the PFGE pattern images. PFGE pattern order displayed is result of BioNumerics similarity analyses using the unweighted pair group-matching algorithm (UPGMA) and the Dice correlation coefficient with a maximum space tolerance of 1.5%. Key represents the isolate designation, sample location the pond number, sample date the month/year of sample collection, and serotype.
