Abstract: Medical helminth parasitizing in the intestines of mammals and humans can interact with and regulate gut microorganisms, alter the homeostasis and balance of host's intestinal microenvironment, and affect the development, progression and prognosis of diseases. In this paper, the study of medical helminth infection on host gut microbiota before and after treatment were summarized from the aspects of intestinal microecology, immune response and metabolic reaction, in order to provide a new perspective and theoretical basis of intestinal flora on the pathogenesis, diagnosis and treatment of parasitic diseases.
