Antimicrobial resistance in breeding pigs in Germany - differences between 2015 and 2023.
Article in Porcine health management, 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
backgroundDirect contact with their offspring during the first few weeks makes sows a potential source of resistant bacteria for fattening pigs and food products derived from pigs. Moreover, staff working with breeding pigs are exposed to their bacterial flora which also includes zoonotic pathogens and antimicrobial resistant bacteria. In this study we investigated the antimicrobial resistance of E. coli and the prevalence and the antimicrobial resistance of Salmonella enterica, cephalosporin-resistant Escherichia coli (CTXR-E. coli) and methicillin-resistant Staphylococcus aureus (MRSA) in breeding pigs in Germany in 2015 and 2023 to identify potential changes in the prevalence and resistance over time during a period of reduction of antimicrobial use in farm animals in Germany.
resultsResistance in E. coli to tetracycline and sulfamethoxazole and the prevalence of CTXR-E. coli decreased in breeding herds between 2015 and 2023 in Germany. The proportion of E. coli that were susceptible to all tested substances increased. In contrast, there were no changes in the herd prevalence of Salmonella and MRSA. Resistance of E. coli to some antimicrobials was associated with the presence of MRSA in the herd and to herd size. Larger herds were more prone to harbour MRSA and CTXR-E. coli.
conclusionsResults demonstrate a minor decrease in AMR in E. coli from breeding pigs in Germany but no decrease in the prevalence of Salmonella or MRSA.
