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

Streptococcus dysgalactiae (S. dysgalactiae ) is a common pathogen of humans and various animals. However, the phylogenetic position of animal S. dysgalactiae isolates and their zoonotic potential remain unclear. Most molecular epidemiological studies explicate beta-hemolytic streptococci according to their MLST and M protein gene (emm) types. Although human S. dysgalactiae isolates are relatively well characterized, the data concerning animal isolates are scarce. Here, we report the molecular characteristics and antimicrobial resistance of S. dysgalactiae strains recovered from sheep and their genetic relationship with isolates from other animal hosts and humans. Overall, 11 PFGE pulsotypes, five MLST sequence types (STs), and two emm types were distinguished, with ST248 and stL1376 being the most prevalent, indicating genetic diversity among tested 17 ovine isolates. Some isolates exhibited resistance to doxycycline (59%), erythromycin (6%), ciprofloxacin (6%), and trimethoprim/sulfamethoxazole (6%), harboring various resistance determinants. Phylogenetic analysis showed that studied ovine isolates grouped together with human S. dysgalactiae isolates from the cases of zoonotic infections. Moreover, some ovine isolates shared identical STs and emm gene sequences with human non-invasive and invasive S. dysgalactiae strains. These findings suggest a possible link between human and ovine isolates and indicate the zoonotic potential of this pathogen.
