The invention comprises administration of an effective amount of bacterial lysate compositions for the treatment of pathological conditions of microbial infections. The present invention can also be used to enhance the immune system to prevent infections by the administration of an effective amount of the compositions.

Provided herein are probiotic vaccines comprising, a recombinant filamentous phage genome comprising a nucleic acid encoding a polypeptide comprising an exogenous peptide epitope, or fragments or variants thereof, selected from the group consisting of: LPESFDGDPASNTAPLQPEQLQVF SEQ ID NO:1; HER2. In particular embodiments of the invention vaccine, the exogenous peptide epitope is functionally expressed on a coat protein selected from the group consisting of: pill, pVI, pVII, pVIII and pIX. Also provided herein are methods of preventing or treating cancer, comprising administering to a patient in need thereof, one or more of the probiotic vaccines provided herein: or one or more of the recombinant phages provided herein

The present invention is directed to isolated bacteriophages having specificity and lytic activity against strains of Campylobacter species, methods of using the bacteriophages, progeny and derivatives derived therefrom, to control the growth of Campylobacter species in various settings (e.g., food safety, sanitation, modulating microbiome, prebiotics, probiotics).
