Digestion liver fluke

Liver flukes also possess cathepsin C and LAP exopeptidases that are orthologous to the schistosome enzymes. These exopeptidases most likely complete the digestive process to yield free dipeptides and amino acids, respectively, from peptides generated by endoprote-olytic cysteine protease activity on host proteins. Both cathepsin C and LAP have been immunolocalized to gastrodermal cells (Carmona et al., 1994 Acosta et al., 1998 J.P. Dalton, unpublished data). 

Several species of trematodes, commonly known as flat worms or flukes, infest the digestive tract, liver, lungs and blood circulation of sheep, goats, cattle and other animals producing a broad spectrum of morbidity and occasional mortality.
