Genomic analysis of multidrug-resistant Salmonellaenterica Serovar Montevideo isolates in China.

PMID 41398904 · 2025

The study identified multiple AMR genes in Chinese S. Montevideo isolates, including beta-lactamases (bla TEM−1B, bla OXA−1, bla LAP−2, bla CTX−M−55, bla CTX−M−65, bla DHA−1), quinolone resistance genes (qnrS2, qnrS1, qnrA1, qnrB6, qnrB4, qepA1), macrolide resistance genes (mphA, mphE, msrE, mphB), tetracycline resistance genes (tetA, tetD, tetB), sulfonamide resistance genes (sul1, sul2, dfrA14, dfrA12, dfrA27, sul3), and chloramphenicol resistance genes (floR, catA2, catB3).
