Faecalibacterium prausnitzii (F. prau),
a key bacterium to treat Crohn’s Disease

Meet Faecalibacterium prausnitzii (F. prau)

WHAT IS F. prau?
F. prau, is a dominant member of the healthy gut microbiome.
It accounts for 5% to 15% of the total fecal microbiome in healthy adults,
which is simply colossal. F. prau is the most extreme example of strict anaerobic
bacteria. In other words, F. prau simply cannot stand oxygen exposure as it has
naturally thrived throughout evolution in our gut in total absence of oxygen.

Meet EXL01, our drug candidate

We discovered that Crohn’s disease patients lacked F. prau while healthy subjects
had it in abundance. We also showed that increasing the level of F. prau in Crohn’s
disease patients could well be associated with longer remission periods, less need
for surgery, and an overall improved quality of life.
That is why at exeliom biosciences, 
we created EXL01.
