Abstract

          
Background and Aim: Capnocytophaga canimorsus is an emerging zoonotic pathogen associated with severe infections, such as sepsis, meningitis, and endocarditis following animal bites. Despite increasing clinical recognition, a comprehensive understanding of global research trends and collaborative patterns remains limited. This study aimed to perform a scientometric analysis of global scientific output on C. canimorsus infections from 2019 to 2024, focusing on research trends, collaboration networks, and thematic evolution within a One Health framework. 
Materials and Methods: A descriptive observational scientometric study was conducted using the Scopus database. A structured search strategy identified 104 relevant documents published between 2019 and 2024. Bibliometric indicators, including publication output, citation metrics, and author h-index, were analyzed using SciVal and Bibliometrix in R. Keyword co-occurrence, thematic evolution, and international collaboration networks were evaluated to map research dynamics. 
Results: A total of 104 documents from 70 sources were analyzed, showing a slight negative annual growth rate (−5.59%). The mean document age was 2.64 years, with an average of 3.17 citations per publication. Research output involved 503 authors and 223 keywords, reflecting moderate thematic diversity but limited international collaboration (6.73%). Original articles predominated (n = 80), followed by reviews and other document types. Publication activity peaked in 2020 and 2022, with most studies appearing in mid-tier journals. Thematic analysis revealed a transition from early focus on infections and dog bites toward meningitis, bacteremia, and zoonotic diseases. Keyword clustering highlighted “meningitis,” “bacteremia,” and “dog bites” as central research themes. Spain and Belgium emerged as leading contributors in international collaborations, although global networking remained limited and unevenly distributed. Research trends increasingly emphasized zoonotic aspects of C. canimorsus within a One Health context. 
Conclusion: This scientometric analysis highlights evolving research priorities in C. canimorsus infections, with increasing emphasis on zoonosis and One Health perspectives. Despite growing scientific interest, limited international collaboration and underrepresentation of low-resource regions persist. Strengthening interdisciplinary and cross-regional partnerships is essential to enhance surveillance, diagnosis, and prevention strategies for this clinically significant zoonotic pathogen.
