Probiotics ameliorate atopic dermatitis by modulating the dysbiosis of the gut microbiota in dogs.
Article in BMC microbiology, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 8 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
backgroundCanine atopic dermatitis (cAD) is a chronic inflammatory disease that significantly reduces the quality of life in dogs. Dysbiosis of the gut microbiota affects skin diseases through the gut-skin axis. Therefore, microbiota-targeted therapy may potentially serve as a new management strategy for cAD. The present study aimed to investigate the association between gut microbiota and cAD and to evaluate the effect of probiotics on the clinical symptoms of cAD and gut microbiota in dogs.
resultsGut microbiota was analyzed at baseline and after 8 and 16 weeks. Baseline analysis revealed significantly lower (p < 0.05) gut microbial diversity in dogs with cAD than in healthy dogs. Differential abundance analysis showed that Fusobacterium, Megamonas, Collinsella, unclassified Clostridiales, Bacillus, Helicobacter, and Caproiciproducens were significantly more abundant in healthy dogs. In contrast, Clostridioides, Erysipelatoclostridium, Clostridium, Terrisporobacter, and unclassified Ruminococcaceae were significantly more abundant in dogs with cAD, In addition, differential abundance analysis showed that the abundance of 46 metabolic pathways were significantly different between healthy dogs and dogs with cAD indicating the dysbiosis of the gut microbiota in cAD. Moreover, the clinical severity of cAD was negatively correlated (p < 0.05) with alpha diversity and the abundance of Fusobacterium and Megamonas. Notably, daily probiotic administration for 16 weeks significantly decreased the clinical severity (p < 0.05). Dogs with good prognoses exhibited significantly increased alpha diversity, whereas those with poor prognoses did not, suggesting that the therapeutic effects of probiotics may be mediated by changes in gut microbial diversity.
conclusionsThis study highlights the association between gut microbiota dysbiosis and cAD in dogs and demonstrates that probiotic administration can effectively ameliorate cAD by improving gut microbial dysbiosis. These findings provide a basis for novel microbiota-based therapies in cAD treatment.
