The Effect of Cefazolin on the Gut Microbiome of Female Rats After Spinal Cord Injury.
Article in Microorganisms, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 2 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
Spinal cord injury (SCI) is a devastating neurological state that could lead to motor, sensory, and autonomic dysfunction. In addition to its direct impact on the central nervous system, SCI exerts systemic effects, including disruption of gut homeostasis and alterations in the gut microbiota, which can contribute to sustained inflammation and hinder functional recovery. While antibiotic administration during the acute phase of SCI is clinically indicated, it may exacerbate microbial dysbiosis. In this study, we investigate the combined effects of SCI and cefazolin treatment on the gut microbiome of female rats. Animals were assigned to three groups: NAÏVE (no intervention), SHAM (cefazolin only), and INJURY (T10 spinal cord contusion plus cefazolin). Cefazolin was administered for seven days after the injury, fecal samples were collected at baseline (day 0), and on days 7, 14, 21, and 28 post-SCI. DNA was extracted and subjected to 16S rRNA gene amplicon sequencing, followed by bioinformatic analysis. Our findings revealed significant microbial dysbiosis in the INJURY group, including reduced alpha diversity and distinct shifts in microbial composition. These changes were most prominent during the acute phase post-SCI. Our findings highlight the compounding effects of spinal trauma and antibiotic exposure on the gut microbiome and suggest that maintaining microbial stability may represent a promising avenue to support recovery after SCI.
