With reinfection rates reaching 94 per cent after deworming treatment for roundworm infection, a combined approach of mass drug administration and environmental controls (water, sanitation, hygiene) could be critical to gaining an upper hand on these endemic infections, the researchers concluded.
The reduction in roundworm intensity is consistent with previous studies where dried seeds of pawpaw were used to eliminate intestinal parasites.
A single dose of de-worming medication is usually not adequate to eliminate roundworms because most dewormers act on the adult worms in the intestines and do not catch the migrating larvae.
Roundworm was found to be the dominant STH in the samples studied.
"By manipulating the hepatic ROS levels in the susceptible mouse strain we hope to determine the importance of the mitochondria and intrinsic ROS in conferring resistance to Ascaris." The lifecycle of the roundworm in humans sees the infection progress from the stomach, following ingestion of viable eggs which hatch as larvae, to the liver before moving to the lungs and returning to the stomach.
Roundworm larvae can also be transferred to the nursing pup or kitten from the mother's milk.

At the meeting, Dr Philip Skuce and Dr Fi Kenyon from Edinburgh's Moredun Research Institute, will give an update on fluke and roundworm research and highlight a few simple steps that will make worm strategies more effective and less likely to result in a resistant parasite problem on the farm.
