Marshfield Evaluation Confirms Ease, Specificity of PathoGenetix System
PathoGenetix, Inc. recently announced that Marshfield Food Safety, LLC, a full service microbiology and chemistry contract testing laboratory, has completed an independent evaluation of PathoGenetix's RESOLUTION™ Microbial Genotyping System. The three-week evaluation tested the speed, utility and ease-of-use of the RESOLUTION instrument, assays and database for food industry applications.
The System isolates and analyzes microbial DNA directly from enriched food and clinical samples, without a pure culture isolate, to strain type target bacteria in just five hours even when multiple serovars are present. In all, Marshfield tested 77 Salmonella isolates sourced from its internal collection of “tough-to-type” strains, as well as several naturally contaminated food samples. Marshfield compared the molecular serotyping capability of the RESOLUTION System to traditional serological analysis, as well as used the strain typing capability of the RESOLUTION System to determine the relatedness of the isolates.
