A global bibliometric analysis of Salmonella Typhi over the past 52 years (1970-2022).

Introduction: Salmonella Typhi (S. Typhi), a bacterial human-restricted pathogen, is an essential systemic health problem of global importance in humans and animals. This study aimed to determine the overall scientific impact of Salmonella Typhi (S. Typhi) research using bibliometric methods.

Methodology: In this research, a bibliometric analysis was performed on S. Typhi using the Web of Science (WoS) database and the Bibliometrix R package. A total of 1,966 articles, published between 1970-2022, were analysed.

Results: This bibliometric analysis showed that the most productive years in the process were 2012 and 2022. This analysis also showed that Infection and Immunity Journal was the leading journal with a total of 1,332 articles in publications related to S. Typhi research, with the USA being the most productive country in S. Typhi publications, as well as having the highest co-authorship collaboration. The University System of Maryland ranked first with 110 records when affiliations were analysed. The United States Department of Health and Human Services was at the top of the Funding Agencies analysis. Analysis of the most cited authors revealed that Parry CM was the first most cited author (n = 90) of S. Typhi publications.

Conclusions: This bibliometric analysis showed that the countries with high economic income were dominant in the studies of published articles, affiliations, and funding agencies on S. Typhi. Collaboration of researchers from countries with low or middle incomes with S. Typhi epidemics and researchers from countries with high economic income will make the fight against these bacteria more effective.
