Ascaris suum is the largest and most common nematode parasite of swine; the egg can remain dormant for long periods of time until favorable conditions for development occur. Early treatment during the migration stage is of economic benefit. Oesophagostomum dentatum is more important in older pigs than in young ones; strains found in the UK seem to be more pathogenic than those seen in the US. Trichuris suis eggs can also persist in the environment for long periods of time; heavy infections cause severe bloody diarrhea and may cause death. Strongyloides ransomi, Metastrongylus spp. and Hyostrongylus rubidus are all more common when pigs are raised outdoors. Stephanurus dentatus is only found in warm temperate areas.
