Zusammenfassung:Lungworm infections (parasitic bronchitis) of sheep and goats are widely prevalent in hilly regions of India and neighbouring countries. Several species of strongyloid nematodes are involved but the most prevalent, and most pathogenic, is Dictyocaulus filaria — responsible for heavy mortality in young animals and severe morbidity in survivors. Control of these parasites now relies on a gamma-attenuated D. filaria vaccine developed in India in 1971. Vaccination of 6-week-old lambs has since become an accepted part of the regular sheep husbandry practice in India, and trials are now underway to extend use of the vaccine to goats, and to set up similar vaccination procedures in other countries. In this review, the authors trace the development of the D. filaria vaccine, highlighting its production and application. Although imperfect, the vaccine is now making a substantial contribution to improved sheep rearing by pastoral in the northern hill areas of India.
