Dominant research themes and year-over-year shifts in Salmonella and Campylobacter epidemiology

What Topics Define the Class of 2026?

Research in the Class of 2026 is prominently anchored by antimicrobial resistance (0.24 normalized frequency) and multidrug resistance (0.22), reflecting an intense global focus on combating drug-resistant foodborne pathogens. Epidemiological characterization centers heavily on specific serotypes, led by Salmonella Typhimurium (0.22), Salmonella Typhi (0.12), and Salmonella Enteritidis (0.10). Genomic surveillance methods, particularly whole genome sequencing (0.10) and the detection of antimicrobial resistance genes (0.12), provide high-resolution insights into strain transmission and resistome evolution across food production chains. Concurrently, the One Health framework (0.10) serves as an overarching paradigm connecting human clinical isolates with animal reservoirs and agricultural environments. Additional key topics include zoonotic transmission dynamics and target pathogens such as Campylobacter jejuni (0.08) and Salmonella Infantis (0.08), alongside emerging investigative areas like lytic phage applications (0.08) and intestinal inflammation (0.06). Together, these themes demonstrate a shift from descriptive outbreak reports toward genomic-backed, interdisciplinary surveillance strategies aimed at controlling recalcitrant enteric pathogens across global food supply networks.

How Did Topics Shift from the Class of 2025 to the Class of 2026?

Comparison between the Class of 2025 and Class of 2026 reveals significant thematic repositioning in foodborne pathogen research. Antimicrobial resistance priorities intensified, with multidrug resistance rising from 0.14 to 0.22 normalized frequency (+57% relative increase) and general antimicrobial resistance expanding to 0.24. Novel therapeutic and biocontrol avenues surged, highlighted by lytic phage (0.08 frequency, up from 0) as researchers explore alternatives to traditional antibiotics. Additional expanding focus areas included Campylobacter jejuni, Salmonella Infantis, and zoonotic transmission, each doubling in normalized frequency from 0.04 to 0.08. Public health modeling also gained traction, evidenced by new appearances of the Global Burden of Disease study (0.06) and enteric fever (0.06). Conversely, whole genome sequencing saw a decline in explicit topic frequency from 0.24 to 0.10, indicating its transition from a novel standalone research topic into standard methodological infrastructure. Traditional focus areas like typhoid fever (0.10 to 0.06) and Salmonella Enteritidis (0.14 to 0.10) also moderated, reflecting a broader pivot toward multi-drug resistant serotypes and alternative antimicrobial strategies.

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.
