A rapid and field-deployable RAA-CRISPR/Cas12a platform for detection of Mycoplasma gallisepticum in poultry.
Article in BMC veterinary research, 2026. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Not yet cited in PubMed.
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
backgroundMycoplasma gallisepticum (MG) is a major pathogen that causes respiratory diseases 14in poultry, resulting in reduced production and severe economic losses. Current MG detection methods are time-consuming, labor-intensive, and expensive. Hence, the rapid and accurate detection of MG is critical for effective disease control. Therefore, this study aimed to develop a dual-mode diagnostic assay for sensitive and specific detection of MG by combining recombinase-aided amplification (RAA) with CRISPR/Cas12a technology. Conserved regions of the mgc2 gene were used for primer and CRISPR RNA design, and the reaction conditions were optimized to maximize detection efficiency.
resultsThe assay achieved a detection limit of 2 copies/µL and demonstrated high specificity against seven other common avian pathogens. Detection was visualized within 1 h using either fluorescence or lateral flow dipstick. Moreover, clinical validation of chicken samples showed complete concordance with quantitative real-time polymerase chain reaction results. Furthermore, an epidemiological investigation revealed that chickens had the highest positivity rate for MG among chickens, ducks, and pigeons in Hubei Province.
conclusionsThis simple, rapid, field-deployable method is valuable for timely MG surveillance and effective disease management in poultry production.
