The invention discloses a microbial marker for treating Crohn's
disease based on coprophilous
fungus transplantation and a
screening method of the microbial marker. The microbial marker comprises the following components: Dialister insight,
Roseburia intestinae, Parabacteroides verdeae,
Bacteroides caccae, Blauria obeum,
Bacteroides intestinae, Paraprevotella, and a combination of the
Bacteroides cactinae, and further comprises the following components in parts by weight: 1, 1, 2, 3, 4, 5, 6, 7, 7, 8, 8, 8, 9, 10, 12, 13, 13, 13, 14, 16, 17, 17, 17, 17, 17, 17, 17, 17, 17, 17, 17, 17, 17, 17, 17, 17, 17, 17, 17, 17, 17 According to the invention, through metagenome sequencing and a
machine learning
algorithm, the key microbial marker which is significantly related to the
symptom improvement of the Crohn's
disease in the coprophilous
fungus transplantation treatment process is screened out, and a scientific basis and a standardized scheme are provided for coprophilous
fungus transplantation treatment of the Crohn's
disease.
