In Ian Lipkin et al 2017 study, high clostridium methylpentosum was reported (on average). [Index to all posts on Study] . This bacteria was first identified on 1989.

• “An intestinal bacterium isolated from a human subject utilized only two methylpentoses (L-rhamnose and L-fucose) and two pentoses (L-lyxose and D-arabinose) as fermentable substrates, among many compounds tested..This organism may participate in intestinal digestive processes by metabolizing rhamnose released via the enzymatic depolymerization of dietary pectin.” [1989]

Bottom Line

We do not know if any antibiotics are effective. The only option is starvation by reducing intake of two methylpentoses (L-rhamnose and L-fucose).
