摘要：
The present invention relates to a novel bacteriophage EC11 having a killing ability specific to pathogenic Escherichia coli, particularly Shiga toxin producing E. coli (STEC) an antibiotic composition, a feed additive composition, a feed, a disinfectant or a washing agent, which all include the bacteriophage and a method for preventing or treating infectious diseases caused by pathogenic Escherichia coli, which includes a step of administrating the bacteriophage to an object. The method for preventing or treating infectious diseases caused by pathogenic Escherichia coli using the bacteriophage EC11 has very high specificity to pathogenic Escherichia coli, and particularly to STEC compared to a conventional chemical material such as antibiotics or the like, and the bacteriophage EC11 is infected to pathogenic Escherichia coli to proliferate in the pathogenic Escherichia coli, thereby having excellent bacteriolytic activity and being strong to physiochemical stimulation. In addition, the bacteriophage EC11 of the present invention is not infected to a host other than bacteria except a human, an animal, a plant, or the like, and thus it is possible to solve a problem of antibiotic resistant bacteria due to abuse of antibiotics, a problem of residual antibiotics in food, and a problem of a wide range of host ranges. Accordingly, the bacteriophage EC11 of the present invention can be variously used in the fields of prevention or treatment of infectious diseases caused by pathogenic Escherichia coli, antibiotic compositions, feed additive compositions, feeds, disinfectants, or washing agents.본 발명은 병원성 대장균, 특히 시가독소 생성 대장균(Shiga toxin producing E. coli, STEC)에 특이적인 사멸능을 갖는 신규 박테리오파지 EC11, 상기 박테리오파지를 포함하는 항생용 조성물, 사료 첨가용 조성물, 사료, 소독제 또는 세척제 및 상기 박테리오파지를 개체에 투여하는 단계를 포함하는 병원성 대장균에 의한 감염성 질병의 예방 또는 치료 방법에 관한 것이다. 본 발명의 박테리오파지 EC11을 이용한 병원성 대장균에 의한 감염성 질병의 예방 또는 치료 방법은 기존의 항생제 등의 화학물질에 비해 병원성 대장균, 특히 시가독소 생성 대장균에 대한 특이성이 매우 높고, 상기 박테리오파지 EC11은 상기 병원성 대장균에 감염하여 균 내에서 증식함으로써 용균
