SEM of H. bakeri incubated in papain or papain + E64. H. bakeri incubated in papain + E64 for 30 min were intact and appeared undamaged (a), whereas worms incubated in 1 µM papain for 10 min or longer showed rapid and extensive digestion and were no longer recognisable (b 10, c 15 min). After 30 min of incubation, all that remained were sheets of insoluble material (d). Bar = 25 µm
