title: Strain differences in faecal tryptic activity of germ-free and conventional rats.
abstract: Regardless of diet (semi-synthetic or lab chow) or strain (AGUS or SD), germ-free rats have tryptic activity in their faeces, whereas conventional rats never do. The activity in faeces from germ-free AGUS rats was significantly higher than from SD rats.
