Abstract: Compositions for the treatment of bovine mastitis are provided. Said compositions comprise as active compound [2-carboxy-4-/2'-(5'-nitrofuryl)]quinoline N-oxide. The method is performed in such a manner that the composition is administered to the animal, preferably by way of intramamary infusion.

Abstract: There are disclosed water-soluble compositions comprising sulfadimidine sulfate, polyvinylpyrrolidine (PVP) and a physiologically acceptable water-soluble salt of pyrimethamine. Said compositions may comprise also a filler substance. There are also disclosed aqueous suspensions comprising the above composition and a method for the treatment of animals suffering from bacterial infections.

Abstract: There are disclosed water-suspendable compositions comprising a 1,3-bis-[(p-chlorobenzylidene)-amino]-guanidine (called Robenidine) or one of its salts. Said compositions comprise also N-methyl-2-pyrrolidone, a protective colloid water and, if required, a buffer yielding to the composition a pH of 7-9.5. Said composition may comprise additional substances, e.g., a potentiated or unpotentiated sulfa drug. There are also disclosed aqueous suspensions comprising the above composition and a method for the treatment of animals being infected with Cocciodiosis with said aqueous suspension.

Abstract: There are disclosed water-soluble compositions comprising a 1,3-bis-[(p-chlorobenzylidene)-amino]-guanidine (called Robenidine) salt, particularly the hydrochloride. Said compositions comprise also a suitable water-soluble organic solvent and a suitable water-soluble solubilizer; the solvent and the solubilizer being miscible with each other. There are also disclosed aqueous solutions comprising the above composition and a method for the treatment of animals being infected with Cocciodiosis with said aqueous solution.
