Compositions and methods for diagnosing and treating degenerative mitral valve disease in a canine
The present invention relates to methods and compositions for diagnosing and treating degenerative mitral valve disease in a canine. In one embodiment, a method of diagnosing early stage degenerative mitral valve disease in a canine can comprise measuring a normalized relative abundance of a biomarker selected from the group consisting of Erysipelatoclostridium, Ruminococcaceae UCG014, Butyricicoccus, Faecalibacterium , and combinations thereof, and determining that the canine has early stage degenerative mitral valve disease if the Erysipelatoclostridium is from 0 to 0.5 normalized relative abundance, the Ruminococcaceae UCG014 is from 0 to 0.1 normalized relative abundance, the Butyricicoccus is from 0 to 0.1 normalized relative abundance, or the Faecalibacterium is from 0 to 0.1 normalized relative abundance.
1. A method of diagnosing early stage degenerative mitral valve disease in a canine, the method comprising:
obtaining a fecal sample from the canine;
measuring a normalized relative abundance of a biomarker in the fecal sample, the measuring comprises extracting fecal DNA from the fecal sample, sequencing the extracted fecal DNA, and performing taxonomy assignment and sequence alignment of the sequenced fecal DNA, the biomarker selected from the group consisting of Erysipelatoclostridium, Ruminococcaceae UCG014, Butyricicoccus, Faecalibacterium , and combinations thereof; and
determining that the canine has early stage degenerative mitral valve disease if the Erysipelatoclostridium is from 0 to 0.5 normalized relative abundance, the Ruminococcaceae UCG014 is from 0 to 0.1 normalized relative abundance, the Butyricicoccus is from 0 to 0.1 normalized relative abundance, or the Faecalibacterium is from 0 to 0.1 normalized relative abundance.
2. The method of claim 1 , wherein the determining is based on two biomarkers.
3. The method of claim 1 , wherein the determining is based on three biomarkers.
4. The method of claim 1 , wherein the determining is based on all four biomarkers.
5. The method of claim 1 , wherein the determining is based on Erysipelatoclostridium.
6. The method of claim 1 , wherein the determining is based on Ruminococcaceae UCG014.
7. The method of claim 1 , wherein the determining is based on Butyricicoccus.
8. The method of claim 1 , wherein the determining is based on Faecalibacterium.
9. The method of claim 1 , further comprising long-term administration on a regular basis of a therapeutically effective amount of a probiotic selected from the group consisting of Butyricicoccus, Faecalibacterium and combinations thereof to the canine having the early stage degenerative mitral valve disease.
