Description

technical field

[0001] The invention belongs to the field of biotechnology and is related to the field of biological prevention and control. The invention specifically relates to a broad-spectrum phage that rapidly lyses Escherichia coli of livestock and poultry and its application. Background technique

[0002] Escherichia coli is an opportunistic pathogenic bacterium that is normally considered part of the normal intestinal flora. Once the body's resistance decreases, some highly pathogenic strains can cause gastrointestinal infections in humans or animals, as well as urinary tract infections, arthritis, meningitis, and sepsis. With the vigorous development and promotion of large-scale and intensive livestock and poultry breeding in my country in recent years, the economic impact of pathogenic Escherichia coli on livestock and poultry breeding has become increasingly obvious, and even threatens the healthy and sustainable development of animal husbandry.
