First of all, proteus can decompose urea to produce
ammonia. We have all heard the smell of
ammonia. The smell of urine
in the toilet is the smell of ammonia. Therefore, the urine odor of PATM patients is produced by Proteus.
In addition, proteus produces indole and hydrogen sulfide in our intestines. Indole is another name for faecal odor. The reason why feces stink is because of the high concentration of indole in feces. The fecal odor of PATM patients is produced by Proteus.
