Background And Aims:
Salmonella enterica is a globally significant foodborne pathogen, with Typhimurium being one of the most prevalent serotypes linked to foodborne illnesses. Despite its importance, there is a notable absence of meta-analytical studies examining the prevalence of this bacterium in Iran. This meta-analysis aims to assess the prevalence of S. Typhimurium in food, animals, and human populations in Iran.
Methods:
Studies on the prevalence of S. Typhimurium published from 1936 to December 2023 were gathered from databases including PubMed, Scopus, Web of Science, and SID. The data collected were analyzed using Stata software.
Results:
A total of 52 studies met the inclusion criteria for the analysis of S. Typhimurium prevalence in clinical and environmental isolates in Iran. The overall prevalence of S. Typhimurium in total isolates from food, animals, and human sources was determined to be 4% (95% CI: 3%-6%). Additionally, the analysis revealed a nearly stable trend in the prevalence of S. Typhimurium over the years.
Conclusion:
The relatively high prevalence of S. Typhimurium in animal isolates underscores the necessity for implementing stricter infection control measures. Furthermore, it is essential to establish appropriate diagnostic criteria and management guidelines for screening this pathogen across various sample types to mitigate its spread.
