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

The restriction-modification (R-M) systems of many bacteria present a barrier to the stable introduction of foreign DNA. The Lyme disease spirochete Borrelia burgdorferi has two plasmid-borne putative R-M genes, bbe02 and bbq67, whose presence limits transformation by shuttle vector DNA from Escherichia coli. We show that both the bbe02 and bbq67 loci in recipient B. burgdorferi limit transformation with shuttle vector DNA from E. coli, irrespective of its dam, dcm, or hsd methylation status. However, plasmid DNA purified from B. burgdorferi transformed naïve B. burgdorferi much more efficiently than plasmid DNA from E. coli, particularly when the bbe02 and bbq67 genotypes of the B. burgdorferi DNA source matched those of the recipient. We detected adenine methylation of plasmid DNA prepared from B. burgdorferi that carried bbe02 and bbq67. These results indicate that the bbe02 and bbq67 loci of B. burgdorferi encode distinct R-M enzymes that methylate endogenous DNA and cleave foreign DNA lacking the same sequence-specific modification. Our findings have basic implications for horizontal gene transfer among B. burgdorferi strains with distinct plasmid contents. Further characterization and identification of the nucleotide sequences recognized by BBE02 and BBQ67 will facilitate efficient genetic manipulation of this pathogenic spirochete.
