A review of research trends on Nattrassia mangiferae from 1966-2022: A bibliometric approach

In recent years, Nattrassia mangiferae has received tremendous attention as a destructive plant pathogen that may potentially infect humans and animals. The pathogen was isolated from 61 species belonging to 47 genera and 30 family plants but was most frequently isolated from Cactaceae, Rosaceae, Euphorbiaceae, Anacardiaceae, and Rutaceae hosts. To systematically and comprehensively describe the progress, trends, and hotspots of N. mangiferae research, the 376 related publications from 1966 to 2022 were collected from the Scopus database. The bibliometric characteristics including publication output, countries/region of focus, author’s productivity, most prolific authors , authorship pattern, citation frequency, institutes, most prolific journ als, and research focus were evaluated by using Excel 2013 and VOSviewer. Out of 376 original articles, there are 139 plant and 237 human studies. The leading countries based on the number of publications were the United States, the United Kingdom, and Brazil. A sharp increase in the number of studies related to the pathogenicity of N. mangiferae during 2018 to 2021 was observed, coinciding with an increase in the number of short reports and outbreak reports worldwide. The journal and subject categories with the most significant publications are Plant Disease and Medical Mycology, respectively. The most common document types were article, note, review, and letter. N. mangiferae is a thermophilic fungus, and warming temperatures may weaken trees and affect their susceptibility to this pathogen. The increase in reports of the pathogenicity of this pathogen on various plants and humans from 70 different countries in recent years shows the importance of this pathogen as a sever threat to the world. Our bibliometric analysis reveals the current research hotspots and topic trends on N. mangiferae , thus offering potential clues for further examination.
