Fluorescent amplified fragment length polymorphism (FAFLP) subtyping analysis was used to genotype multiresistant Salmonella enterica serovar Typhimurium definitive phage type 104. Thirteen distinct FAFLP profiles were found among 85 isolates exhibiting identical pulsed-field gel electrophoresis (PFGE) profiles. A single FAFLP profile was shared by 93% of outbreak-associated isolates and 82% of sporadic isolates. This study demonstrates the value of FAFLP as a high-resolution tool for epidemiological investigation of Salmonella.
