Exploiting Broad-Spectrum Chimeric Lysin to Cooperate with Mupirocin against Staphylococcus aureus-Induced Skin Infections and Delay the Development of Mupirocin Resistance.

ABSTRACT: Staphylococcus aureus often leads to severe skin infections. However, S. aureus is facing a crisis of antibiotic resistance. The combination of phage and antibiotics is effective for drug-resistant S. aureus infections. Therefore, it is worth exploiting novel antibacterial agents to cooperate with antibiotics against S. aureus infections. Herein, a novel chimeric lysin ClyQ was constructed, which was composed of a cysteine- and histidine-dependent amidohydrolase/peptidase (CHAP) catalytic domain from S. aureus phage lysin LysGH15 and cell wall-binding domain (CBD) from Enterococcus faecalis phage lysin PlyV12. ClyQ had an exceptionally broad host range targeting streptococci, staphylococci, E. faecalis, and E. rhusiopathiae. ClyQ combined with mupirocin (2.64 log reduction) was more
