- (Lactobacillus acidophilus NT and Bifidobacterium longum NT) and type strains (L. acidophilus JCM1132(T) and B. longum JCM1217(T) ) …inhibit the growth of Sutterella wadsworthensis.” 
- “Doripenem, a synthetic 1-beta-methyl carbapenem, has a broad-spectrum of activity against almost all species of anaerobic bacteria, including all Bacteroides fragilis group species,..(with the exception of Sutterella wadsworthensis). 
- “No metronidazole resistance was seen in gram-negative anaerobes other than S. wadsworthensis (18% resistant);”  
- ” Over 95% of S. wadsworthensis are susceptible to amoxicillin“
This is a patent for using S. wadsworthensis to treat Rheumatoid arthritis as a probiotic. [Patent filed 2014]
We may have a probiotic available (at least in China) that may increase this bacteria in the near future.
