目的：从家蝇幼虫体内分离出粪产碱菌，并观察其抑菌能力。方法：对家蝇幼虫匀浆，按常规方法分离细菌，在无菌条件下进行抑菌试验。结果：粪产碱菌对金黄色葡萄球菌、绿脓杆菌等致病菌有很强的抑菌能力。动物实验证实，蝇蛆粉能治愈绿脓杆菌感染的创伤。结论：蝇蛆体内可能存在一组微生物，参与机体的防御体系，保护它们在极其恶劣的环境中存活。
OBJECTIVE: To separate Alcaligenes faecalis from housefly larvae and to observe its antibacterial activity. Methods: The Musca domestica larvae were homogenized, and the bacteria were separated by the conventional method. The antibacterial activity was tested under aseptic conditions. Results: Alcaligenes faecalis had strong antibacterial activity against pathogenic bacteria such as Staphylococcus aureus and Pseudomonas aeruginosa. Animal experiments confirmed that maggot powder can cure Pseudomonas aeruginosa infection trauma. CONCLUSIONS: There may be a group of microorganisms in the fly maggot that participate in the defense system of the body to protect them in extremely harsh environments.
