Since 1936, 762 phials of anti-indistinctus serum have been issued in South Africa. Antiï¿½mactam serum has been shown to neutralise L. indistinctus venom at high dilutions. Anti-mactans serum has been shown to protect mice against the bite of L. indistinctus.
A case of pyo-pneumopericardium is recorded. The failure of response to paracentesis, operative drainage, sulfadiazine and penicillin therapy is noted. This failure was ascribed to adhesive mediastinopericarditis which had supervened.
