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

Peptidoglycan (PG) acetylation of Gram-positive bacteria confers lysozyme resistance and contributes to survival in the host. However, the importance of PG acetylation in Gram-negative bacteria has not been fully elucidated. The genes encoding putative PG acetyltransferase A (PatA) and B (PatB) are highly conserved in Campylobacter jejuni, the predominant cause of bacterial diarrhea worldwide. To evaluate the importance of PatA and PatB of C. jejuni, we constructed patA and patB isogenic mutants and compared their phenotypes with those of the parental strains. Although transmission electron microscopy did not reveal morphological changes, both mutants exhibited decreased motility and biofilm formation in vitro The extent of acetylation of the PG purified from the patA and patB mutants was significantly lower than the PG acetylation in the parental strains. Both mutants exhibited decreased lysozyme resistance and intracellular survival in macrophage cells. In a chick colonization experiment, significant colonization deficiency was observed for both mutants. These results suggest that PatA and PatB of C. jejuni play important roles in maintaining cell wall integrity by catalyzing PG O-acetylation and that the loss of these enzymes causes decreased motility and biofilm formation, thus leading to colonization deficiency in chicken infection. IMPORTANCE: The importance of peptidoglycan (PG) acetylation in Gram-negative bacteria has not been fully elucidated. The genes encoding putative PG acetyltransferase A (PatA) and B (PatB) are highly conserved in Campylobacter jejuni, the predominant cause of bacterial diarrhea worldwide. We evaluated the importance of these enzymes using isogenic mutants. The results of this study suggest that PatA and PatB of C. jejuni play important roles in maintaining cell wall integrity. The loss of these factors caused multiple phenotypic changes, leading to colonization deficiency in chicken infection. These data should be useful in developing novel control measures to prevent chicken colonization by C. jejuni Inhibitors of the PG acetylation enzymes PatA and PatB might serve as potent anti-C. jejuni agents.
