Abstract: The present invention provides methods and compositions to reduce growth of microbial colonies, including infections, and includes therapeutic compositions, methods for treatment of infections, and methods for identifying additional such compositions.

Abstract: The present invention provides methods and compositions to reduce prevalence of plasmids in microbial colonies, including infections, and includes therapeutic compositions, methods for treatment of infections, and methods for identifying additional such compositions. Means are provided to reduce the copy numbers of antibiotic resistance genes, and to confer phage binding to cells lacking receptors for those phage.

Abstract: Provided herein are antibacterial compositions and methods of making and using the compositions.

Abstract: The present invention features incapacitated whole-cell bacterial immunogenic compositions and methods of their production, which compositions are useful to deliver antigens in a manner resembling the live infectious organism in terms of elicitation of a robust immune response, but with reduced risk or no risk of disease. The compositions of the invention are produced by rendering a bacterium bacteriostatic through expression of a recombinant promoter in the bacterial cell, which promoter can be operably linked to a polynucleotide encoding a recombinant gene product. In one embodiment, where the bacterium is a gram negative host, the recombinant gene product provides for reduced toxicity of LPS. In one embodiment, the gene product is a bacteriophage protein, such as endolysin, holin, or ndd.

Abstract: Soluble variants of recombinant proteins produced in a prokaryotic host cell, where the high expression levels often cause the original proteins to aggregate into insoluble inclusion body aggregates. The variant polypeptides retain biological function while increasing protein solubility with comparable or higher recoverable levels of biologically active protein when expressed in a suitable expression host. Methods of identifying critical residues and substituting them are provided to produce the variants.

Abstract: The invention provides therapeutic, defined-dose anti-bacterial phage preparations, methods to make such preparations, methods to treat bacterial infections using such preparations and methods to diagnose bacterial infections using such preparations.

Abstract: The present invention features therapeutic bacteriophage deficient in the lysin protein (“Lys minus” phage). Lys minus bacteriophage are incapable of facilitating efficient lysis of the bacterial host since the enzymatic activity of the lysin of the phage is needed for breaking down the peptidoglycan layer of the bacterial cell wall. Lys minus bacteriophage retain activity in invasion of its appropriate bacterial host, destruction of the bacterial genome, and replication, which are sufficient to inhibit bacterial growth and replication. Therefore, the therapeutic Lys minus phage stops the spread of infection by the bacterial pathogen without lysis of the bacterium. This approach is attractive as it also prevents the release of the phage progeny, thus reducing or eliminating the potential for generation of immune responses against the phage. The incapacitated bacterial pathogen is then removed by the normal defense systems such as phagocytes and macrophages.
