Anika Singla, M.S. student is using pulsed field gel electrophoresis (PFGE) to distinguish among multiple isolates of the same serovar of Salmonella recovered from a seven-year survey of almonds. A collaboration with the Almond Board of California, the original study has tested over 12,000 almond samples with over 100 separate isolates of Salmonella. The Salmonella isolates have been characterized by antibiotic-resistance profile but PFGE has helped to further distinguish individual strains. These data are useful in understanding potential routes of contamination of almonds. The first five years of the study were previously published. Uesugi, A. R., M. D. Danyluk, R. E. Mandrell and L.
