[Acute bovine mastitis caused by clostridium perfringens type A (Author's transl.)]

An acute case of bovine mastitis caused by clostridium perfringens type A is described. The condition appeared before delivery and was characterised by gas formation in the udder and severe general signs. In spite of parenteral treatment with large doses of penicillin and streptomycin combined with frequent stripping of the udder the animal died two days after the onset of symptoms. The strain isolated proved sensitive to penicillin, chloramphenicol and tetracyclin, but resistant to streptomycin and sulphonamides.
