Disclosed herein is an attenuated Acinetobacter baumannii comprising an expression vector comprising a nucleic acid encoding the ABUW_1645 protein or a variant thereof. Disclosed herein are methods of treating or preventing colonization, infection, or disease by an Acinetobacter baumannii microbe, the method comprising administering a clinically effective dose of the attenuated Acinetobacter baumannii to a subject in need thereof, wherein the attenuated Acinetobacter baumannii comprises an expression vector expressing the ABUW_1645 protein or variants thereof.

The present invention relates to proteins derived from Acinetobacter Baumanii, nucleic acids encoding the proteins, antibodies specific for the proteins as well as methods of therapy, prophylaxis, and diagnosis that utilise the proteins, nucleic acids, and antibodies.

The present invention relates to compositions comprising Moraxella catarrhalis (M. catarrhalis) Ubiquitous surface protein A2 (UspA2). More particularly, the present application relates to UspA2 protein constructs and immunogenic compositions comprising the constructs, vaccines comprising such immunogenic compositions and therapeutic uses of the same. The invention further relates to compositions comprising UspA2 in combination with at least one antigen from Haemophilus influenzae, immunogenic compositions comprising the antigens, vaccines comprising such immunogenic compositions and therapeutic uses of the same.

The present invention provides antigenic polypeptides expressed during an infection by a pathogenic organism, such as Acinetobacter and compositions comprising these polypeptides. The invention further provides compositions for use in treating, preventing or detecting a bacterial infection, in particular vaccine compositions using the antigenic polypeptides. The invention further provides antibodies directed to said antigenic polypeptides.
