Taint­ed do­na­tions from stool bank reignite safe­ty con­cerns about poop trans­plants

Last year, the death of an im­muno-com­pro­mised el­der­ly pa­tient in a fe­cal mi­cro­bio­ta trans­plan­ta­tion (FMT) tri­al at the Mass­a­chu­setts Gen­er­al Hos­pi­tal — due to a stool do­na­tion that con­tained a rare type of E. coli bac­te­ria — sent shiv­ers across the field.

Now, an­oth­er in­ci­dent has come to light — this time em­a­nat­ing from the non-prof­it stool bank Open­Bio­me — in which taint­ed stool made six pa­tients sick, four of whom were hos­pi­tal­ized. Two oth­er FMT re­cip­i­ents whose trans­plants com­prised Open­Bio­me’s prod­uct al­so died.
