摘要： 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 mu g/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 mu g/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.
