The effectiveness of extended binding affinity of prophage lysin PlyARI against Streptococcus suis infection.
Article in Archives of microbiology, 2021. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 2 papers.
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
Streptococcus suis is an important zoonotic pathogen. An increase in multi-drug-resistant strains has led to poor performance of traditional antibiotic therapies. Thus, alternative antibacterial agents are urgently needed. In this study, we identified a recombined and expressed lysin PlyARI derived from the novel serotype S. suis (Chz) prophage PhiARI0460-1. The recombinant PlyARI at a concentration of 10 µg/mL showed high bacteriolytic activity against 30 S. suis isolates. The minimum inhibitory concentration (MIC) of PlyARI against S. suis was found to be as low as 2 µg/mL, and the lytic efficiency could be maintained between the range of pH 4 and 12. Additionally, in a mouse infection model, a dose of 0.5 mg of PlyARI protected 10 out of 10 mice that were challenged with highly virulent S. suis strain HA9801. Furthermore, the binding specificity of PlyARI was evaluated by constructing a green fluorescent protein (GFP-ARIb), where GFP was fused with the PlyARI-SH3b (cell wall-binding domain, CBD), revealing a high affinity to S. suis, Staphylococcus aureus, and Streptococcus equi along with exhibiting a medium affinity to Streptococcus pneumoniae as well as Streptococcus agalactiae. Overall, our findings indicated that PlyARI may be an alternative antibacterial agent that was useful in treating and possibly the prevention of Streptococcal infections.
