Global Spread and Molecular Characterization of CTX-M-Producing Salmonella Typhimurium Isolates.

ABSTRACT: This study aimed to determine the global prevalence and molecular characterization of CTX-M-producing Salmonella Typhimurium isolates. A total of 330 (15.2%, 330/21779) bla_CTX-M-positive S. Typhimurium were obtained from the public databases in July 2021. Thirteen variants were found in the 330 members of the bla_CTX-M group, and bla_CTX-M-9 (26.4%, 88/330) was the most prevalent. The majority of bla_CTX-M-positive S. Typhimurium were obtained from humans (59.7%, 197/330) and animals (31.5%, 104/330). The number of bla_CTX-M-positive S. Typhimurium increased annually (p < 0.0001). These isolates were primarily found from China, the United Kingdom, Australia, the USA, and
