Rational Design of a Phage Cocktail for Effective Control of Multidrug-Resistant Uropathogenic
Article in Antibiotics (Basel, Switzerland), 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
backgroundThe emergence of multidrug-resistant (MDR) uropathogenic
methodsHere, we identified clinical MDR-UPEC strains AT82 and AT84 collected from hospitalized patients that display extensive antimicrobial resistance at both genetic and phenotypic levels. Due to their high resistance profile, we systematically customized a phage cocktail from our coliphage library using hierarchical clustering based on host specificity and candidate selection through bacterial suppression profiles.
resultsThis pipeline yielded four lytic coliphages, designated Phi25-4, Phi25-6, Phi50-4, and Killian. Their genomes are relatively large ranging from 112-169 kbp and cluster into two distinct lineages comprising two closely related groups: Phi25-4/Phi50-4 and Phi25-6/Killian. Although each phage exhibited potent antibacterial activity, none alone sustained bacterial suppression during prolonged treatment. To overcome this limitation, we systematically compared the antibacterial activity of all possible phage combinations.
conclusionsThe four-phage cocktail outperformed all two- or three-phage formulations, sustaining significant growth inhibition of AT82 and AT84 for up to 16 h and reducing area under the curve by more than 80% relative to controls. Cocktail potency was dose-dependent, with lower phage doses yielding the least viable cells at 48 h. Additionally, this cocktail exerted prophylactic action, significantly reducing UPEC invasion by several orders of magnitude, while the phage cocktail alone induced minimal proinflammatory cytokine responses in human bladder epithelium. Together, these findings provide an effective phage cocktail and a complementary framework for cocktail design against urinary tract infections caused by MDR bacteria.
