Evaluation of an alternative positive control strain of Salmonella enterica subsp. enterica serovar Typhimurium for microbial assays.

ABSTRACT: Officially certified microbiological testing methods utilize positive control strains to enhance experimental reproducibility and ensure standardized procedures among experimenters. Salmonella enterica subsp. enterica serovar Typhimurium ATCC 14028 is designated as a positive control strain for microbiological testing by the International Organization for Standardization, the Korean Pharmacopoeia, and Ministry of Food and Drug Safety (MFDS) foodborne investigation methods. However, using such foreign strains involves complicated import procedures and significant financial burdens. In this study, we aimed to select a domestic isolate strain that can replace S. Typhimurium ATCC 14028. The target strains used were S. Typhimurium strains preserved in the Korean Culture Collection for foodborne
