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

Staphylococcus aureus, a commensal and a pathogenic bacterium, causes a wide variety of diseases in humans and animals with a high impact on public health and the livestock industry. The risk of zoonotic transmission to humans highlights the need to understand the molecular ecology of S. aureus in foods. In this study, we obtained 25 S. aureus isolates from 39 crayfish samples in Hubei, China. PCR was applied for detection of presence of virulence and methicillin resistance genes in the pathogen genome. The result revealed that all of the 25 S. aureus isolates harbored at least four virulence genes, and 64 % of them were positive for five or more virulence genes. The most predominant virulence genes were coa, α-HL and β-HL genes (100 %), followed by sea (68 %), fnbA (60 %), tsst-1 (36 %), while none of the examined isolates presented positive for mecA gene conferring methicillin resistance. Subsequently, all of the isolates were assessed for phenotypic biofilm formation with the microtiter plate assay. The results showed 92 % isolates could produce biofilm with different forming capacity. Multilocus sequence typing divided the isolates into five sequence types (STs), three of which (ST1920, ST188 and ST398) were the same with the isolates from livestock and clinic in China. This study provides preliminary insights into the genetic diversity and virulence gene profiles of S. aureus from crayfish, suggesting that S. aureus isolates from crayfish is a potential hazard for consumers and deserves further attention.
