Lungworm

  • Lungworm is an economically important parasitic nematode infection of the respiratory tract of cattle.
  • The causative parasite (Dictyocaulus viviparus) is widespread throughout the British Isles, Western Europe and other parts of the world being commonest in temperate climates with a high rainfall.
  • Disease due to lungworm may also be referred to as parasitic bronchitis, colloquially known as “husk” or "hoose".
  • The disease occurs typically in young calves at grass for the first time when members of a group may be coughing and showing other respiratory symptoms.
  • Adult cattle usually acquire immunity to lungworm infection but if immunity becomes reduced or impaired, may cough and in dairy cows show a drop in milk yield.
