Protective Effects of Lactobacillus-Derived Probiotics and Postbiotics on Renal and Reproductive Function in Escherichia coli-Infected Rats.
Article in Veterinary medicine and science, 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
backgroundEscherichia coli infections of the genitourinary tract are a major cause of renal and reproductive dysfunction in males, often impairing spermatogenesis and fertility. Probiotics and postbiotics have emerged as microbiota‑based interventions with strain‑specific immunomodulatory and antioxidant properties.
objectivesThis experimental study evaluated the effects of a probiotic or postbiotic supplementation containing Lactobacillus helveticus, Lactobacillus rhamnosus, and Lactobacillus casei on renal and testicular tissues, as well as sperm parameters, in male Wistar rats infected with E. coli.
methodsTwenty-eight male Wistar rats (200-220 g) were randomly assigned to four groups: control, E. coli-infected, E. coli + probiotic (10
resultsE. coli infection significantly impaired renal and testicular histology, elevated pro‑inflammatory and pro‑apoptotic gene expression, reduced TAC, and deteriorated sperm parameters. Probiotic and postbiotic supplementation mitigated these effects, restoring antioxidant capacity, enhancing Bcl‑2 expression, reducing IL‑6 and TNF‑α levels, and improving sperm viability and morphology. Histological evaluation confirmed partial recovery of kidney and testicular structures in treated groups.
conclusionMulti‑strain probiotic-postbiotic mixtures confer protective effects against infection‑induced oxidative stress, apoptosis, and inflammation in renal and testicular tissues, while improving sperm quality. These findings highlight their translational potential as adjunctive therapies for infection‑associated male infertility and renal impairment.
