The use of fecal matter in the treatment of a subject having autoimmune disease, wherein the fecal matter is autologous to the subject, and preferably administered to the small intestine, preferably the duodenum, of the subject. The fecal matter can be one or more constituents of autologous feces, preferably chosen from the group consisting of bacteria, viruses, bacteriophages, fungi, metabolites, microRNAs, proteins, antibodies, and/or antigens.

The present invention relates to utilizing engineered horizontal gene transfer elements and high-throughput selection strategies to tag and retrieve genetically modified native commensal strains from the mammalian gut. In certain aspects, the present invention relates to methods wherein isolated bacteria from the mammalian gut microbiome that were amenable to genetic manipulation were redeployed back into the mammalian subject as host-optimized engineerable probiotics.

The present disclosure belongs to the technical field of biomedicine, and provides use of Faecalibacterium prausnitzii in preparation of a medicine for treating pathological ventricular remodeling and/or heart failure following myocardial infarction. The Faecalibacterium prausnitzii can improve pathological ventricular remodeling and/or heart failure caused by myocardial infarction in experimental animals, resume the systolic function, reduce the cardiac fibrosis, and inhibit the pathological myocardial hypertrophy of mice with myocardial infarction. Furthermore, the inactivated Faecalibacterium prausnitzii has no such improvement effect.
