Abstract

Plesiomonas shigelloides is an emerging pathogen with damaging effects on human health such as gastroenteritis and extraintestinal infections. Here, we carried out a bibliometric survey that aimed to examine publication trends in Plesiomonas-related research by time and place, international collaborative works, identify gaps and suggest directions for future research. The search term “Plesiomonas shigelloides” was used to retrieve articles published between 1990 and 2017 from the Web of Science database. Only primary research articles were included in the analysis. A total of 155 articles were published within the survey period, with an average of 5.54±2.66 articles per year and an annual growth rate of −0.8%. Research output peaked in 2000 and 2006 (each accounting for 7.7% of the total). The United States ranked first in terms of numbers of articles (n = 29, 18.1%) and total citations (n = 451). Cameroon, Canada, Cuba, Switzerland and Turkey co-shared the 10th position each with 2 articles (1.3%). Research collaboration was low (collaboration index = 3. 32). In addition to Plesiomonas shigelloides (n = 82, 52.9%), the top Authors Keywords and research focus included lipopolysaccharide and nuclear magnetic resonance (n = 13, 8.4%). Diarrhea (n = 43, 27.7%), Aeromonas species (n = 41, 26.5%) and infections (n = 31, 20.0%) were also highly represented in Keywords-Plus. Authors’ collaborations and coupling networks formed two mega-clusters which nodes were shared solely by authors from high-income countries. The common conceptual framework in retrieved articles determined by K-means clustering revealed three clusters with sizes of 7, 16, and 29, representing research responses focused on extraintestinal and gastroenteritis, P. shigelloides lipopolysaccharide structure, and co-infections, respectively. Our bibliometric analysis revealed a global diminishing research in Plesiomonas; greater research outcomes from high-income countries compared to others and low collaboration with developing countries.

Highlights

Plesiomonas shigelloides is a bacterium that has been labeled as an emerging pathogen for over three decades
Some food and waterborne outbreaks have been traced to P. shigelloides [8,9,10,11,12,13], and the incidence of Plesiomonas infections linked to immunocompromised health [14] is increasing, especially in light of present-day lifestyles [15]

Summary

Introduction

Plesiomonas shigelloides is a bacterium that has been labeled as an emerging pathogen for over three decades. Climate change and global warming are predicted to contribute to increased incidence of waterborne infectious diseases including Plesiomonas infections [16,17,18,19]. Accurate estimates of the incidence of Plesiomonas-related gastroenteritis and extraintestinal infections both globally and at the level of individual countries remain unknown [1,2,4,5,6,7,10,20,21,22,23,24,25,26,27,28,29,30,31,32,33,34,35,36,37]. P. shigelloides is not routinely examined in clinical settings, and as such, awareness regarding this pathogen remains limited
