Bibliometric analysis of the global research trends of Klebsiella studies from 2000-2019

Abstract

Background: Klebsiella are major opportunistic bacteria pathogens known to cause a series of severe nosocomial infections. This study reports the global research outputs of Klebsiella research studies and explores the key areas within Klebsiella research studies. Methods: Data in published articles on Klebsiella research studies from 2000 to 2019 were recovered from a scientific data bank known as Web of Science (WoS). Bibliometric tools together with Microsoft Excel 2016 were employed to analyse the top ranked journals, trend topics, title word occurrences, global cited documents, most relevant authors, most relevant countries by corresponding authors, most cited countries, country collaboration networks, title word occurrence, trend topics, most relevant affiliations, and conceptual structural map. Results: An aggregate of 6,047 published papers were retreived from Web of Science (WoS) and the analyses showed that Antimicrobial Agents and Chemotherapy was the top journal in research on Klebsiella with an aggregate of 441 published research documents, followed by Jong G, 2009 as the major global cited article with a total of 1339 citations, Li J as the most relevant author with 72 publications, China as the most relevant country by corresponding author with a total of 1,303 articles and the USA as the most cited country with a total of 33,882 citations. Furthermore, the results from the analyses also showed that China was the major country with the highest collaboration network followed by Zhejiang University as the major relevant university with 243 affiliations, Klebsiella as the highest title word with 32% and Enteriobacteriaceae as the major trend topic on Klebsiella research outputs between 2000-2019. Conclusion: This current analysis provides qualitative and quantitative assessments of title word occurrences, the foremost ranked journals, utmost cited research articles, and most significant researchers in Klebsiella research for the studied period (2000-2019).
