The present invention is generally related to engineered bacteriophages expressing antimicrobial peptides or lytic enzymes or fragments thereof for targeting a broad spectrum of bacterial hosts, and for the long-term suppression of bacterial phage resistance for reducing bacterial infections. In some embodiments, bacteriophages express antimicrobial peptides or antimicrobial polypeptides (e.g. phage lytic enzymes) which are secreted from the host bacteria, or alternatively released upon lysis of the bacterial host cell. Aspects of the present invention also relate to the use of the engineered bacteriophages for the reduction of bacterial infections, both in a subject or for bioremediation purposes, in clinical settings and wound healing.
本发明一般涉及表达抗菌肽或溶菌酶或其片段的工程噬菌体,用于靶向广谱细菌宿主,长期抑制细菌的噬菌体抗药性,以减少细菌感染。在某些实施方案中,噬菌体表达的抗菌肽或抗菌
多肽(如噬菌体溶解酶)是从宿主细菌中分泌出来的,或者在细菌宿主细胞裂解时释放出来。本发明的各方面还涉及使用工程噬菌体来减少细菌感染,包括在临床环境和伤口愈合中用于主体或
生物修复目的。
