Microbiome and resistome dynamics in different stages of commercial broiler production with restricted antimicrobial use.
Article in BMC microbiology, 2026. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 3 papers.
What it found
Each row is one number read from the abstract, on the scale the paper reported it, with its interval. Left of the dashed line favours the treatment, right favours the comparator. Under each row is the sentence it came from. New to these charts? A ten-minute tutorial.
The abstract states no effect estimate the extractor could read, or names no intervention and outcome on the map, so this paper lights no cell and moves no belief. It is still indexed, cited and linked below.
The trial behind it
Trials whose registry record cites this paper, or whose number appears in the abstract. A trial that started after this paper was published is citing it as background, not reporting it.
Neither the registry nor the abstract names a trial number. If this is a trial report, that itself is worth knowing.

Abstract
backgroundAntimicrobial use (AMU) in poultry production is central to curb the Antimicrobial Resistance (AMR) crisis. Institutional and market pressure led many commercial poultry operations to practice distinct levels of AMU restriction. On-farm data remains one of the main bottlenecks in understanding the impacts of AMU restriction at the farm level and across production systems. However, AMR dynamics in company-wide production chains remain largely unexplored, precluding improvement of AMU policies and stewardship. STUDY
aimHere, we shotgun sequenced soil and litter samples from 26 poultry farms and carcass rinses from a processing plant to reconstruct the microbiome and resistome of two vertically integrated commercial poultry operations to explore their dynamics under AMU restriction.
resultsShotgun sequencing revealed that litter microbiome and resistome changed significantly by production stage and company, reflecting management practices and possible effects of historical AMU. Meanwhile, broiler farms had increased detection of potential pathogens and AMR diversity. We found no evidence of farm-to-fork transmission. Effective biosecurity protocols largely maintained the separation between the internal and external environments of the poultry houses, except on two farms where breaches might have led to external spread of pathogens and AMR.
conclusionOur study highlights that AMR in commercial poultry system reflects the combined effect of production-stage, company practices, and environmental boundaries. Future studies should integrate quantitative AMR data and culture-based techniques with metagenomic findings to strengthen tracking and surveillance of AMR in poultry farm environments.
