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

backgroundMelioidosis is a tropical infectious disease which is being increasingly recognised throughout the globe. Infection occurs in humans and animals, typically through direct exposure to soil or water containing the environmental bacterium Burkholderia pseudomallei. Case clusters of melioidosis have been described in humans following severe weather events and in exotic animals imported into melioidosis endemic zones. Direct transmission of B. pseudomallei between animals and/or humans has been documented but is considered extremely rare. Between March 2015 and October 2016 eight fatal cases of melioidosis were reported in slender-tailed meerkats (Suricata suricatta) on display at a Wildlife Park in Northern Australia. To further investigate the melioidosis case cluster we sampled the meerkat enclosure and adjacent park areas and performed whole-genome sequencing (WGS) on all culture-positive B. pseudomallei environmental and clinical isolates.

resultsWGS confirmed that the fatalities were caused by two different B. pseudomallei sequence types (STs) but that seven of the meerkat isolates were highly similar on the whole-genome level. Used concurrently with detailed pathology data, our results demonstrate that the seven cases originated from a single original source, but routes of infection varied amongst meerkats belonging to the clonal outbreak cluster. Moreover, in some instances direct transmission may have transpired through wounds inflicted while fighting.

conclusionsCollectively, this study supports the use of high-resolution WGS to enhance epidemiological investigations into transmission modalities and pathogenesis of melioidosis, especially in the instance of a possible clonal outbreak scenario in exotic zoological collections. Such findings from an animal outbreak have important One Health implications.
