Abstract
Summary : A clinical syndrome in sheep, which persisted since several years at the Hawatka Breeding Station (Assiut province) and was cha racterised by subcutaneous abscesses mostly affecting young animals (between 4 months and two years of age), is described. No deaths were observed but the condition appeared to be incurable. It had never been reported elsewhere in Egypt. The causative pathogen was isolated and identified as Streptococcus faecium. To control the disease, the following actions were undertaken and gave very satisfactory results : surgical intervention on diseased animals; hygienic and environmental sanitation measures, disinfection; protection of susceptible animals through vaccination using either a kil led formolised vaccine, made from locally isolated strains of S. faecium and containing Freund's incomplete adjuvant, or BCG, acting as a non-specific immunopotentiator. Epidemiological and immunological aspects of these findings are discussed.
