TL;DR
This paper characterizes a Salmonella strain from Peruvian swine, analyzing its antibiotic resistance and genome.
Contribution
The study provides new genomic and antimicrobial resistance data for a Salmonella Rissen strain from Peru.
Findings
The strain FARPER-637 carries resistance genes blaTEM-1B, tet(A), and qnrB19.
Phenotype-genotype agreement was observed except for colistin resistance.
No plasmid-mediated resistance genes were found for colistin resistance.
Abstract
We report the antimicrobial susceptibility profile and genomic features of the Salmonella enterica serovar Rissen strain FARPER-637 isolated from Peruvian swine in 2025. Nanopore sequencing revealed blaTEM-1B, tet(A), and qnrB19. Phenotype–genotype concordance was observed except for colistin, which lacked known plasmid-mediated resistance determinants.
