Global research hotspots and trends in brucellosis: a bibliometric and visualization analysis based on CiteSpace and...

This study aims to elucidate the global research dynamics of brucellosis through bibliometric visualization analysis. The findings have major implications for advancing academic progress in the field of brucellosis research, fostering interdisciplinary collaboration, and strengthening disease prevention and control.

The Web of Science Core Collection database was utilized as the data source for this study, and literature published between January 1, 1901, and December 31, 2024 was retrieved. CiteSpace and VOSviewer software tools were employed to conduct a visual analysis of the publication volume, countries, institutions, authors, journals, and keywords.

A total of 12,810 articles were included in this analysis, with the first publication dating back to 1901.The annual publication volume has increased over the years. The United States had the highest volume of publications and intermediary centrality. The United States Department of Agriculture (USDA) and the journal Infection and Immunity were found to be the most influential. Professors Kim S. and Pappas G. have made the most significant contributions to the field of brucellosis. Keyword analysis indicated that the top five high-frequency keywords were "brucella abortus," "infection," "brucella melitensis," "diagnosis," and "cattle." Among the five formed clusters, cluster #0 (virulence) was larger and newer, with persisting research hotspots. In the keyword burst analysis, the keyword "elisa" exhibited the highest burst strength of 41.47. Recent emerging keywords include "one health," "risk factors," and "seroprevalence."

This study indicates that brucellosis research is predominantly concentrated in developed countries such as the United States. Professor Pappas is a key contributor in this research area. The "one health" approach to brucellosis is a current research hotspot. Based on these findings, future studies focused on content, methods, and value may represent a new trend in brucellosis research.
