Lung Worm

Verminous Pneumonia


Causes:

  • Verminous Pneumonia in goats is commonly caused by infection with Dictyocaulus filaria, Muellerius capillaris, or Protostrongylus rufescens.
  • Affected goats have diffuse pneumonia without nodular lesions.

Symptoms:

Clinical signs usually consist of:

  • Chronic Fever
  • Cough
  • Thick Nasal Discharge
  • Increased Respiratory Rate
  • Poor Appetite and Weight Loss.

Transmission:

  • Verminous Pneumonia can be spread by heavy pasture contamination and unknowingly contaminated goats that move to an uninfected pasture. These parasites prefer low lying, moist pastures. Heavy pasture contamination with these parasites can occur from high stocking densities.

Treatment:

  • Lungworm infections in herds or flocks are controlled primarily by vaccination or anthelmintics.
  • Ivermectin (200 – 300 μg/kg SC)
  • Fenbendazole (7.5 – 15mg/kg orally)

Prevention:

  • Larval stages of M. capillaris may survive in the pasture from one season to the next, so goats may be reinfected. Try to prevent contact with snails and slugs, which are intermediate hosts for the parasite.
