present in the intestine of many parasitic nematodes as well 

 as at least one amylytie enzyme. Demonstrations of lipases 

 have been impossible or questionable. Although little research 

 has been done on digestion in parasitic nematodes, the demon- 

 stration of these enzymes lends weight to the hypothesis that 

 digestion in parasitic nematodes is essentially like that of other 

 animals possessing a digestive tract.
