Salmonella Typhi research in lower-middle-income economy countries: a bibliometric analysis (1990-2023)

Introduction: Salmonella Typhi continues to be a significant global public health concern. The objective of this study was to evaluate the literature pertaining to S. Typhi in lower-middle-income countries from 1990 to April 31, 2023. Methodology: The bibliographic data was collected from the Web of Science database. Various bibliometric tools were utilized to conduct bibliometric analysis and visualization. Numerous bibliometric parameters were assessed, including the top publishing organizations, countries, institutions, authors, journals with the highest publication output, citation counts, commonly used keywords, and emerging research topics. Results: The current study included a total of 4,031 articles. These articles exhibited an annual growth rate of 8.17%. Over the past 33 years, there has been a gradual increase in the overall quantity of articles. On average, these articles received 18.82 citations. A total of 13,987 authors from 3,665 affiliations and 118 countries contributed to these publications. The majority of publications originated from India (50.31%), Pakistan (15.40%), Nigeria (6.32%), Bangladesh (5.03%), and Iran (4.89%). Among the institutions, Oxford University published the highest number of articles (302), followed by the University of Karachi (124). The frequently used keywords included "Salmonella Typhi" (frequency = 231), "antimicrobial activity" (frequency = 191), and "resistance" (frequency = 190). Conclusions: The findings of this study can serve as a foundation for future studies, enabling researchers to identify knowledge gaps and areas for further investigation. The data can also aid in health planning, providing insights into the current research landscape and highlighting priority areas for intervention and resource allocation.
