What is lung worm?

Answer 1

LUNGWORMS

Lungworms are a type of roundworm that can be found in the lungs and/or bronchial tissues of goats. Called protostrongylids, there are at least five types of lungworms, two kinds of which are commonly found throughout the United States in areas of heavy rainfall. Wet and undrained pastures are prime areas for lungworms.

The lungworm's larvae gets inside the goat's body when the animal eats an infected slug or snail. Some types of lungworms don't need the snail or slug as a host; instead, they develop into the infective stage on plants that the goat ingests. Adult worms lay eggs in the goat's lungs or bronchial tissue. The eggs hatch into larvae, which are then coughed up and swallowed and pass through the goat's body and into its feces. They are white and thin in appearance and can be three inches in length. The lungworm's life cycle ranges between five and ten weeks. It remains infective to the goat for at least one year.

Answer 2

Lung worms are worms that live the the bronchioles and tracheas of sheep. goats and cattle. There are three different species of lung worm, each living in a different section of the lungs - Dictyocaulus filaria, the large lungworm of sheep and goats, is a slender, whitish worm 3-10 cm long. Adults live mainly in the airways (bronchi) in the lung. D. viviparus occurs in cattle. This is an extremely important parasite in Britain and increasingly so in continental Europe. D. viviparus causes parasitic bronchitis, known in Britain as 'husk'.Protostrongylus ('small lungworm') and Muellerius spp. ('small or nodular lungworm') occur in Australia but are of little importance. P. rufescens is parasitic in sheep, goats and deer. Adults are reddish, mainly inhabit bronchioles (small airways) and are 16-35 mm long, smaller than D. filaria. Lesions are broadly similar to those produced by D. filaria and M. capillaris.M. capillaris parasitises sheep and goats. Adults live in the lung tissue, rarely the airways, and usually provoke an enveloping inflammatory response, hence the common name, 'nodular lungworm'.
