Lungworms of Pigs
METASTRONGYLUS species
- Found in the bronchioles and smaller bronchi.
- Three species, but these are all very similar.
- Look like the Dictyocaulus species in ruminants and produce similar pathology.
- Very pathogenic and can cause severe lung damage.
- Even low level infections will check growth.
- Immunity develops quickly.
- Larvated eggs with a wavy outline passed in faeces.
- Intermediate host is the earthworm, therefore this only affects outdoor pigs.
- Becoming more common with the trend towards free-range husbandry.
- Infection occurs when the earthworm is eaten.
- Larvae migrate via the mesenteric lymph nodes to the lungs.
