A Bibliometric and Trend Analysis on Primary Amebic Meningoencephalitis

Background: In this study, bibliometric methods were used to investigate research trends on Primary Amebic Meningoencephalitis (PAM). Methods: Data from 1970 to 2021 were acquired from the Web of Science database. The inclusion condition was developed as follows: "Primary Amebic Meningoencephalitis," TS (Topic). The research trend was explored by examining the distribution of nations, journals, authors, funding organizations, author keywords, affiliations, authorship patterns, and co-authorship relationships. Results: Out of a total of 339 documents retrieved, 244 (71.976%) were journal articles. The highest number of publications (7.377%) were made in 2021. Over the past 20 years, there has been a gradual increase in the number of publications in PAM research and 47.54 (%) of the articles were published since 2010. The articles were from 34 different research fields, mainly in Microbiology (27.869%), Parasitology (20.902%), and Infectious Diseases (13.115%). Articles on PAM have been published from 39 countries on 5 continents. The number of articles is only a few hundred, mainly from the United States, Australia, Europe, and some Asian countries over the past fifty years. The only country with more than 100 (n=117) articles in PAM research was the United States of America (USA). The articles that were published in the USA had 5240 total citations (21.48 per article), and their average H index was 37. Conclusion: The number of published articles on PAM is limited in countries other than the USA. Increasing the number of articles published on PAM by countries other than the USA would contribute to the literature.
