PARASITIC bronchitis, otherwise known as lungworm, husk or hoose, occurs worldwide, predominantly in areas with a warm, wet climate for at least part of the year. In Great Britain, the disease is most common in the wetter western parts of the country. Parasitic bronchitis has traditionally been a disease of calves in their first season at pasture. However, since 1993 adult animals appear to have become the predominant age group affected, in a period which has seen a marked increase in the levels of disease generally. These recent changes in the epidemiology of the disease suggest that it is necessary to re‐evaluate the control measures adopted.
