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 putative carboxyl-terminal processing protease (CtpA) of Brucella suis 1330 is a member of a novel family of endoproteases involved in the maturation of proteins destined for the cell envelope. The B. suis CtpA protein shared up to 77% homology with CtpA proteins of other bacteria. A CtpA-deficient Brucella strain (1330DeltactpA), generated by allelic exchange, produced smaller colonies on enriched agar plates and exhibited a 50% decrease in growth rate in enriched liquid medium and no growth in salt-free enriched medium compared to the wild-type strain 1330 or the ctpA-complemented strain 1330DeltactpA[pBBctpA]. Electron microscopy revealed that in contrast to the native coccobacillus shape of wild-type strain 1330, strain 1330DeltactpA possessed a spherical shape, an increased cell diameter, and cell membranes partially dissociated from the cell envelope. In the J774 mouse macrophage cell line, 24 h after infection, the CFU of the strain 1330DeltactpA declined by approximately 3 log(10) CFU relative to wild-type strain 1330. Nine weeks after intraperitoneal inoculation of BALB/c mice, strain 1330DeltactpA had cleared from spleens but strain 1330 was still present. These observations suggest that the CtpA activity is necessary for the intracellular survival of B. suis. Relative to the saline-injected mice, strain 1330DeltactpA-vaccinated mice exhibited 4 to 5 log(10) CFU of protection against challenge with virulent B. abortus strain 2308 or B. suis strain 1330 but no protection against B. melitensis strain 16 M. This is the first report correlating a CtpA deficiency with cell morphology and attenuation of B. suis.
