Topic trends
Dominant research themes and year-over-year shifts in Mycobacterium research and diagnosis
What Topics Define the Class of 2026?
Research in the Class of 2026 cohort is overwhelmingly anchored by Mycobacterium tuberculosis, which appears in 56% of top-cited publications as studies focus on resolving drug resistance mechanisms and improving clinical diagnostics. Genomic surveillance and resistance profiling represent the central methodological pillars of the field, led by whole-genome sequencing (14%), drug susceptibility testing (12%), and targeted identification of drug resistance mutations (8%). Specifically, resistance to critical therapeutics—most notably rifampicin resistance (8%), isoniazid resistance (6%), and second-line drugs (8%) including bedaquiline (6%)—dominates translational investigation. Clinical disease management centers on multidrug-resistant tuberculosis (10%) and pulmonary tuberculosis (10%), backed by molecular diagnostic tools such as Xpert MTB/RIF Ultra (6%) and phenotypic assays quantifying minimum inhibitory concentration (6%). While nontuberculous mycobacteria (8%) and associated pulmonary disease (6%) remain notable secondary areas of focus, the core momentum of the field is overwhelmingly dedicated to combating drug-resistant tuberculosis through integrated genomic, diagnostic, and pharmacological approaches.

How Did Topics Shift from the Class of 2025 to the Class of 2026?
Comparison between the Class of 2025 and Class of 2026 cohorts highlights a pronounced shift toward actionable drug resistance surveillance and specialized diagnostic modalities. Investigation of Mycobacterium tuberculosis itself expanded substantially, rising from 42% to 56% of top publications. Emerging focus areas registered notable gains, with second-line drugs advancing from zero representation to 8% of top papers, alongside the rise of non-human primate models (6%), tongue swab testing (4%), and machine learning applications (4%) for diagnostic interpretation. Conversely, research on opportunistic non-tuberculous pathogens experienced a marked decline: nontuberculous mycobacteria dropped from 20% to 8%, Mycobacterium avium complex decreased from 12% to 4%, and Mycobacterium abscessus fell from 12% to 6%. Broad methodologies like whole-genome sequencing saw slight moderation (from 18% to 14%) as efforts pivoted from general sequencing toward targeted clinical application. Overall, the field transitioned away from broad non-tuberculous species surveys toward focused clinical strategies addressing complex drug-resistant tuberculosis.

Methodology
PRI identifies high-impact research using a transparent, topic-agnostic framework applied consistently across scientific domains. Bibliographic records are drawn from OpenAlex, including publication dates, citation relationships, and document types.
This ranking covers the Class of 2026 cohort: journal articles published in 2024. Reviews and other non-article document types are excluded to ensure comparability.
Research impact is quantified with an 18-month post-publication citation window—the number of citing works published within 18 months of each paper's publication date. This metric captures early impact while controlling for publication age.
An LLM-based relevance classifier then reviews each candidate's title and abstract to confirm substantive alignment with the target domain. Only papers classified as relevant appear in the final ranking.
