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

The population genetic structure of the animal pathogen Staphylococcus intermedius is poorly understood. We carried out a multilocus sequence phylogenetic analysis of isolates from broad host and geographic origins to investigate inter- and intraspecies diversity. We found that isolates phenotypically identified as S. intermedius are differentiated into three closely related species, S. intermedius, Staphylococcus pseudintermedius, and Staphylococcus delphini. S. pseudintermedius, not S. intermedius, is the common cause of canine pyoderma and occasionally causes zoonotic infections of humans. Over 60 extant STs were identified among the S. pseudintermedius isolates examined, including several that were distributed on different continents. As the agr quorum-sensing system of staphylococci is thought to have evolved along lines of speciation within the genus, we examined the allelic variation of agrD, which encodes the autoinducing peptide (AIP). Four AIP variants were encoded by S. pseudintermedius isolates, and identical AIP variants were shared among the three species, suggesting that a common quorum-sensing capacity has been conserved in spite of species differentiation in largely distinct ecological niches. A lack of clonal association of agr alleles suggests that assortive recombination may have contributed to the distribution of agr diversity. Finally, we discovered that the recent emergence of methicillin-resistant strains was due to multiple acquisitions of the mecA gene by different S. pseudintermedius clones found on different continents. Taken together, these data have resolved the population genetic structure of the S. intermedius group, resulting in new insights into its ancient and recent evolution.
