The isolated strains underwent multiple tests, including antimicrobial susceptibility testing, pulsed-field gel electrophoresis (PFGE), and whole-genome sequencing (WGS). Based on the WGS data, analyses were conducted, including serotype prediction, resistance gene prediction, multilocus sequence typing (MLST), core genome multilocus sequence typing (cgMLST), single nucleoBMC infectious diseases943https://www.ebi.ac.uk/biostudies/studies/S-EPMC12291336biostudies-literatureEpidemiological and molecular investigation of a Salmonella Agona-associated foodborne outbreak in Taiyuan, Shanxi Province, China, 2022.PMC12291336Wu JLi YZhang XJia XLiang LZheng WMiao LWang JXu JAn TZhang PXu YfalseEpidemiological and molecular investigation of a Salmonella Agona-associated foodborne outbreak in Taiyuan, Shanxi Province, China, 2022.<h4>Background</h4>From July 23 to 24, 2022, Qingxu People's Hospital in Taiyuan reported an increase in acute gastroenteritis cases among individuals who had dined together.An investigation was initiated to identify factors associated with acute intestinal infection and to prevent further illness.<h4>Methods</h4>To isolate, cultivate, and identify pathogens, we collected samples from patients, food, and the environment.
