biostudies-literatureUnknown65Le NT<h4>Background</h4><i>Salmonella</i> spp. is a prominent causative agent of pediatric diarrhea, with recent research emphasizing the rising concern regarding antimicrobial resistance (AMR), particularly involving colistin, a last-resort antibiotic.<h4>Methods</h4>This study involved the collection of 500 stool samples from children with diarrhea from two tertiary pediatric hospitals in Ho Chi Minh City. Conventional methods were used to isolate <i>Salmonella</i> spp., and antibiotic resistance profiling against seven antibiotics was conducted using the disk diffusion method. Colistin resistance was determined by the microdilution method. Colistin resistance (<i>mcr</i>) genes were detected by PCR assay.
