Abstract: The present invention relates to the field of non-specific anti inflammatory drugs (NSAIDs). In particular, the invention relates to bismuth(III) tris-carboxylate complexes having the formula [Bi(III)L3]n including its pharmaceutically acceptable salts and solvates, wherein, L is chosen from the group comprising carboxylato-NSAIDs, their derivatives, prodrugs or metabolytes, and n is ?1. The bismuth(III) tris-carboxylate complexes of the invention may be formulated for use in treatments for a wide range of ailments, particularly those where an anti-microbial activity is advantageous. In a particularly preferred embodiment the bismuth(III) tris-carboxylate complexes of the present invention exhibit activity against bacteria found in the gastrointestinal tract such as Helicobacter pylori, Escherichia coli, Klebsiella pneumoniae, Bacillus pumilus, Staphylococcus aureus and Staphylococcus epidermidis.

Abstract: There is provided an immunogenic composition capable of inducing protective antibodies against Helicobacter infection characterized in that it comprises: i) at least one sub-unit of a urease structural polypeptide from Helicobacter pylori (SEQ ID NO: 22,26), or a fragment thereof, said fragment being recognized by antibodies reacting with Helicobacter felis urease (SEQ ID NO: 20-21), and/or at least one sub-unit of a urease structural polypeptide from Helicobacter felis (SEQ ID NO: 20-21), or a fragment thereof, said fragment being recognized by antibodies reacting with Helicobacter pylori urease (SEQ ID NO: 22-26); ii) and/or, a heat shock protein (Hsp), or chaperonin, from Helicobacter, or a fragment of said protein. The preparation, by recombinant means, of such immunogenic compositions is also provided.
