Genetic analysis of an Erysipelothrix rhusiopathiae swine isolate determined to be serovar 2 by a gel double diffusion test but serovar 1a/2 by a serotyping PCR assay.

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
We previously developed a multiplex PCR assay for the differentiation of serovar 1a, 1b, 2 and 5 strains of Erysipelothrix rhusiopathiae. In this study, we analyzed the serovar-defining chromosomal region of a serovar 2 swine isolate, which was PCR-positive for both serovars 1a and 2 by the multiplex PCR assay. Genetic analysis of the chromosomal region revealed that, as in serovar 1a strains, the ERH_1440 gene, which is usually truncated or missing in serovar 2 strains, was intact in this strain. This paper first shows an E. rhusiopathiae serovar 2 strain possessing an intact ERH_1440 gene and suggests that care may be needed when determining the serovar of such rare strains by PCR assay.
