Global landscape of Vibrio parahaemolyticus research: a bibliometric analysis

Vibrio parahaemolyticus poses a notable threat to marine ecosystems and can cause infections and disease outbreaks in seafood species, which can affect humans upon consumption. The global impacts of such infections and outbreaks on human and animal health led to a growing number of studies from various countries discussing the prevention, control, treatment, and overall implications of V. parahaemolyticus. Hence, this study aims to retrieve relevant studies on V. parahaemolyticus using a bibliometric analysis to understand current research status, trends, and hotspots regarding this bacteria. Relevant literature was searched across the Scopus database, and the data were subsequently analyzed using Biblioshiny software. In addition, a manual examination was conducted to identify the hosts of V. parahaemolyticus and diseases caused by the bacteria. Overall, 7,096 records were obtained from Scopus from 1963 to 2023. A bibliometric analysis identified 17,220 authors, with China emerging as the global leader. The analysis also highlighted significant keywords such as "Vibrio parahaemolyticus," "Litopenaeus vannamei," and "innate immunity," suggesting a focus on the impact of V. parahaemolyticus on L. vannamei, specifically emphasizing the shrimp's innate immune responses. Host-disease interaction network also uncovered 53 interactions between hosts and diseases involving L. vannamei or Penaeus vannamei as the primary host, with acute hepatopancreas necrosis disease (AHPND) emerging as the most prevalent among them. This study can enhance our understanding of infections caused by V. parahaemolyticus and contribute to the development of effective strategies for their prevention and management.
