Panoramic quantitative and visualization-based bibliometric analysis of Mycoplasma pneumoniae.

Purpose: Severe pneumonia, refractory pneumonia and extrapulmonary complications caused by mycoplasma pneumoniae infection were increasing, posing a serious threat to health. This study aimed to explore a breakthrough for further investigations in further.

Methods: The Web of Science Core Collection was queried using the search term TS = "mycoplasma pneumoniae" for articles from January 1, 2009, to September 24, 2024. Bibliometric indicators were analyzed using VOSviewer, Pajek, and Scimago Graphica, while CiteSpace was utilized for visual analyses, including the contributions of different countries/regions, institutions, authorship patterns, journals, co-citations, keywords, and genes.

Results: 3,093 articles were collected and showed an increase interest in MPP research. China was the most prolific contributor, and the USA demonstrated the strongest collaboration willingness. The USA and China had the highest cooperation frequency and closest research relationship. The UK had the highest single-article citation count. Fudan University had the greatest total link strength. The top keywords were "Mycoplasma Pneumoniae" and "community-acquired pneumonia", with "children" being particularly prominent throughout the literatures. "risk factors" and "plastic bronchitis" may represent emerging hotspots in MPP research. Antibiotic therapy, herpes simplex virus infections, and serology detection were the high interest surrounding topics over past decade. mNGS, severe community-acquired pneumonia, co-infections of adenovirus or RSV may become focal points in future. CRP and IL-17 A represented significant genes among MP infection. Positive regulation of cytokine production played a critical role in MP infection.

Conclusion: This bibliometric analysis provides insights into its status, frontiers, and hotspots, offering essential guidance to address challenges in MP.
