Probiotic Engraftment and Suppression of Canine Otitis Externa Pathogens by Probiotic Ear Drops.
Article in Veterinary dermatology, 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
backgroundLactobacillaceae have shown promise with their potential to outcompete pathogens and restore a healthy microbial balance in otitis externa (OE). HYPOTHESIS/
objectivesThis study aimed to evaluate the presence of viable Lactobacillaceae over time and in vitro ability to inhibit growth of common OE pathogens. ANIMALS: Fifteen healthy dogs were enrolled and randomised into five groups (n = 3 per group) to receive six probiotic ear drops containing live Lactiplantibacillus plantarum YUN-V2.0 and Lacticaseibacillus rhamnosus YUN-S1.0. MATERIALS AND
methodsEar swabs were taken 24, 48, 72, 96 h and 7 days post single application for culturing. For pathogen inhibition, clinical isolates of Pseudomonas aeruginosa, Staphylococcus pseudintermedius and Malassezia pachydermatis were tested against the probiotic ear drop and antimicrobial disks of florfenicol 30 μg, gentamicin 30 μg, marbofloxacin 5 μg, miconazole 10 μg, neomycin 120 μg and terbinafine 1.5 μg.
resultsA relatively basal low abundance of commensal and Lactobacillaceae micro-organisms was detected (1.34 × 10 CONCLUSIONS AND CLINICAL RELEVANCE: These results suggest that probiotic strains exhibit excellent retention and can inhibit the growth of S. pseudintermedius, P. aeruginosa, and M. pachydermatis.
