Clostridium zhoujianii sp. nov., a novel gram-negative species isolated from bat feces and its genetic characteristics.
Article in BMC microbiology, 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
A strictly anaerobic, rod-shaped bacterial strain, designated LP20ᵀ, was isolated from the intestinal contents of bats collected in Qiandongnan, China. Phylogenetic analysis of the 16 S rRNA gene revealed that strain LP20ᵀ shared its highest similarity with Clostridium paraputrificum ATCC 25780ᵀ (98.10%), a value below the accepted threshold for species delineation. Whole-genome sequencing further supported its taxonomic novelty, with ANI, dDDH, and AAI values to the closest relatives all falling well below species-level cutoffs. Strain LP20ᵀ exhibited unusual Gram-stain-negative morphology, grew optimally at 30–37℃ and pH 7.0–8.0, and possessed distinctive fatty acid and polar lipid profiles, including the presence of an unidentified aminophospholipid. Phenotypic assays revealed several metabolic and enzymatic traits that differentiated LP20ᵀ from its closest phylogenetic neighbors. 16 S rRNA amplicon sequencing and metagenomic screening confirmed the presence of this species in multiple bat hosts, suggesting a wider distribution within bat gut microbiomes. Functional genomic analysis indicated enrichment of genes involved in carbohydrate metabolism and a limited antibiotic resistance profile. Based on polyphasic evidence, strain LP20ᵀ represents a novel species within the genus Clostridium, for which the name Clostridium zhoujianii sp. nov. is proposed. The type strain is LP20ᵀ (= JCM 37970ᵀ = GDMCC 1.5627ᵀ).
