Protective efficacy of a canine brucellosis vaccine candidate based on live attenuated Salmonella expressing recombinant Brucella BCSP31, Omp3b and SOD proteins in Beagles.

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
The aim of this study was to establish a proof-of-concept of protective efficacy of Salmonella-based B. abortus vaccine candidate in Beagles. Group A Beagles (n=10) were subcutaneously (SC) inoculated with S. Typhimurium delivery strain containing pMMP65 (vector to deliver antigens) only as vector control. Group B Beagles (n=10) were SC vaccinated with the mixture of the three Salmonella delivery strains expressing the recombinant B. abortus BCSP31, Outer membrane protein 3b (Omp3b), and superoxide dismutase (SOD) proteins, respectively. No Salmonella delivery strains were isolated from all tissues tested. Serum IgG, interleukin-4, tumor necrosis factor-alpha, and interferon-gamma concentrations were significantly higher in group B than in group A. Following intraconjunctival challenge with B. abortus 544, among 5 group B Beagles, the challenge strain was isolated from mandibular, and retropharyngeal lymph nodes of three Beagles, and no isolates were observed from all tissues of two Beagle. However, the challenge strains were detected from spleen, uterus (except two Beagles), and mandibular, prescapular, retropharyngeal, and superficial inguinal lymph nodes of all group A Beagles. These results suggest that the mixture of three S. Typhimurium delivery strains be a good vaccine candidate against brucellosis by B. abortus in dogs. Further investigations are needed to improve the protective efficacy of the Salmonella-based B. abortus vaccine candidate and explore its practical application in dogs.
