1 · What the graph read from it

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.

2 · The registry

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

Lactobacillus gasseri is an endogenous species of the human gastrointestinal tract and vagina. With recent advances in microbial taxonomy, phylogenetics, and genomics, L. gasseri is recognized as an important commensal and is increasingly being used in probiotic formulations. L. gasseri strain ADH is lysogenic and harbors two inducible prophages. In this study, prophage adh was found to spontaneously induce in broth cultures to populations of ∼ 10(7) PFU/ml by stationary phase. The adh prophage-cured ADH derivative NCK102 was found to harbor a new, second inducible phage, vB_Lga_jlb1 (jlb1). Phage jlb1 was sequenced and found to be highly similar to the closely related phage LgaI, which resides as two tandem prophages in the neotype strain L. gasseri ATCC 33323. The common occurrence of multiple prophages in L. gasseri genomes, their propensity for spontaneous induction, and the high degree of homology among phages within multiple species of Lactobacillus suggest that temperate bacteriophages likely contribute to horizontal gene transfer (HGT) in commensal lactobacilli. In this study, the host ranges of phages adh and jlb1 were determined against 16 L. gasseri strains. The transduction range and the rate of spontaneous transduction were investigated in coculture experiments to ascertain the degree to which prophages can promote HGT among a variety of commensal and probiotic lactobacilli. Both adh and jlb1 particles were confirmed to mediate plasmid transfer. As many as ∼10(3) spontaneous transductants/ml were obtained. HGT by transducing phages of commensal lactobacilli may have a significant impact on the evolution of bacteria within the human microbiota.
