Piglets from 0–50 days of age were exposed to infective Ascaris suum eggs at dose levels varying from 50–10,000 eggs. A clear inverse relationship was found between the inoculated egg doses and the numbers of worms found in the intestine. Thus, p

The early life-cycle of the pig round worm, Ascaris suum, involves well-defined larval development in the liver, lungs and finally the small intestine. Distinct regional immune responses to larval antigens of A. suum were observed in the draining lym

An experiment was undertaken to study the effect of dietary carbohydrates with different digestibility on the populations of Oesophagostomum dentatum in the intestinal tract of pigs. Sixty-four worm-free pigs from a specific pathogen-free farm were r
