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

Nisin A is the most widely characterized lantibiotic investigated to date. It represents one of the many antimicrobial peptides which have been the focus of much interest as potential therapeutic agents. This has resulted in the search for novel lantibiotics and more commonly, the engineering of novel variants from existing peptides with a view to increasing their activity, stability and solubility.The aim of this study was to compare the activities of nisin A and novel bioengineered hinge derivatives, nisin S, nisin T and nisin V. The microtitre alamar blue assay (MABA) was employed to identify the enhanced activity of these novel variants against M. tuberculosis (H37Ra), M. kansasii (CIT11/06), M. avium subsp. hominissuis (CIT05/03) and M. avium subsp. paratuberculosis (MAP) (ATCC 19698). All variants displayed greater anti-mycobacterial activity than nisin A. Nisin S was the most potent variant against M. tuberculosis, M. kansasii and M. avium subsp. hominissuis, retarding growth by a maximum of 29% when compared with nisin A. Sub-species variations of inhibition were also observed with nisin S reducing growth of Mycobacterium avium subsp. hominissuis by 28% and Mycobacterium avium subsp. paratuberculosis by 19% and nisin T contrastingly reducing growth of MAP by 27% and MAC by 16%.Nisin S, nisin T and nisin V are potent novel anti-mycobacterial compounds, which have the capacity to be further modified, potentially generating compounds with additional beneficial characteristics. This is the first report to demonstrate an enhancement of efficacy by any bioengineered bacteriocin against mycobacteria.
