Polymerase spiral reaction assay for rapid visual detection of Mycobacterium avium subsp. paratuberculosis in fecal samples.

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.
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
A rapid, sensitive, and specific visual detection assay for Mycobacterium avium subsp. paratuberculosis (MAP) was developed and optimized using a polymerase spiral reaction (PSR) method. A pair of primers was designed targeting MAP specific sequence of IS900 putative transposes (p43) gene, and PSR results were assessed using agarose gel electrophoresis and colour change with SYBR Green-I dye. The assay was optimized using water bath and the optimum reaction time and temperature for MAP-PSR were 60 min and 64 °C, respectively. The sign of target amplification can be visualized by naked eyes as SYBR Green-I change its colour due to intercalation with amplified products. The developed assay demonstrated that the primers specifically detected MAP and showed no cross-reaction with other common Mycobacterium. The sensitivity of the PSR assay for MAP detection was 122 fg or ~ 23 copy number of the template. The MAP-PSR assay was also evaluated using 100 clinical samples, and a total 59 samples were found positive. When same samples were tested by conventional PCR, 50 samples were found positive, and all PCR positive clinical samples were found positive by MAP-PSR too. In conclusion the developed MAP-PSR assay is simple, rapid, specific, and sensitive, and thereby very suitable for application and promotion in the field and resource limited laboratories.
