Abstract

Official abstract text for this publication.

The invention relates to methods, kits and compositions for reducing the level of or eliminating Bacteroides in situ. The invention encompasses methods of preventing myocarditis, treating myocarditis or dilated cardiomyopathy, or limiting progression of myocarditis toward dilated cardiomyopathy in a subject in need thereof, comprising reducing the amount of Bacteroides sp. in the subject. The invention further encompasses methods of diagnosis of a subject as having myocarditis or dilated cardiomyopathy. The invention also encompasses compositions preventing myocarditis, treating myocarditis or dilated cardiomyopathy, or limiting progression of myocarditis toward dilated cardiomyopathy in a subject in need thereof.

First claim

Opening claim text (preview).

We claim: 1. A method of limiting progression of myocarditis toward dilated cardiomyopathy (DCM) in a subject in need thereof, comprising reducing the amount of B. thetaiotaomicron and/or B. faecis in the subject by orally or enterally administering to the subject an effective amount of a recombinant phage or packaged phagemid that targets the B. thetaiotaomicron and/or B. faecis and encodes a Clustered Regularly Interspaced Short Palindromic Repeats (CRISPR)-Cas nuclease and a guide RNA that are designed to specifically cleave the genome of the B. thetaiotaomicron and/or B. faecis to reduce the amount of the B. thetaiotaomicron and/or B. faecis in the intestine of the subject. 2. The method of claim 1 , wherein the CRISPR-Cas nuclease is Cas9. 3. The method of claim 1 , wherein the CRISPR-Cas nuclease is Cpf1 (Cas12a). 4. The method of claim 1 , wherein the CRISPR-Cas nuclease is Cas 3. 5. The method of claim 1 , wherein the recombinant phage or packaged phagemid is enterally administered to the subject. 6. The method of claim 1 , wherein the recombinant phage or packaged phagemid is orally administered to the subject. 7. The method of claim 1 , wherein the recombinant phage or packaged phagemid targets the B. thetaiotaomicron.
