Herein we describe construction of a select agent-excluded B. mallei ΔtonB Δhcp1 (CLH001) vaccine strain and demonstrate its ability to protect against acute respiratory glanders. Particularly, CLH001 is shown to be attenuated, safe, and effective at protecting against lethal B. mallei challenge. This strain should be useful in vaccines are for use in humans and animals, e.g., equines, in treating or providing immunoprotection against infections elicited by category B, tier 1 pathogens, in particular Burkholderia mallei (Bm) and B. pseudomallei, the causative agents of human glanders and melioidosis, respectively.

Provided herein are methods for using compositions that include a fusion protein having a YscF protein domain, a mature F1 protein domain, and a LcrV protein domain. In one embodiment the composition is used to confer immunity to plague, such as pneumonic plague, caused by Yersinia pestis. In one embodiment, the composition is administered to a mucosal surface, such as by an intranasal route. In one embodiment, the administration to a mucosal surface includes a vector that has a polynucleotide encoding a fusion protein, where the fusion protein includes a YscF protein domain, a mature F1 protein domain, and a LcrV protein domain. The administration is followed by a second administration by a different route, such as an intramuscular route. The second administration includes a fusion protein having the same three domains, and in one embodiment the fusion protein is the same one administered to a mucosal surface.

The present invention is related to a polypeptide comprising an amino acid sequence, whereby the amino acid sequence of the polypeptide is at least 80% identical to a stretch of consecutive amino acids of the region of HPGGT comprising an amino acid sequence corresponding to SEQ.ID.No. 1, whereby such region is defined by (a) amino acid positions 150 to 200 of the amino acid sequence according to SEQ.ID.No.1, or (b) amino acid positions 410 to 480 of the amino acid sequence according to SEQ.ID.No.1, and
whereby the polypeptide is suitable to elicit an immune response which is capable of inhibiting the catalytic activity of HPGGT.

The present invention relates generally to the field of nutrition, health and wellness. In particular the present invention relates to probiotics and ways to increase their effectiveness. One embodiment of the present invention relates to a combination of probiotics with SIgA and possible uses of this combination. For example a use of a composition comprising SIgA and at least one probiotic for the preparation of a product to treat or prevent inflammation is disclosed.

This disclosure features compositions that include two or more staphylococcal toxoids and are useful for inducing protective immune responses against staphylococcal diseases.

The present invention relates to a method for inhibiting, improving, or preventing aging, comprising administering to a subject in need thereof a composition comprising a recombinant protein of flagellin, which is the constituent of Vibrio vulnificus flagella, fused with a pathogenic protein antigen, which is pneumococcal surface protein A (PsaA) of Streptococcus pneumonia. According to the present invention, the recombinant protein of the present invention can improve external and internal aging-related malfunctions and enhance immunity. Also, the composition of the present invention can easily perform immunization through mucosal administration.

The disclosure provides methods, compositions, and kits for enhanced detection of microbes in samples and monitoring of antimicrobial activity in a subject.

The present disclosure relates to a composition for preventing and treating Mycoplasma synoviae infection, the composition comprising Tuf, NOX, MS53-0285 or a combination thereof as active ingredients. The composition of the present disclosure is effective in alleviating symptoms caused by Mycoplasma synoviae infection and can be used as an effective tool in preventing or treating poultry diseases.

The present invention relates to a technology and method of priming of an immune response using invariant chain linked antigen, when these are used to prime a subsequent booster immunization using any suitable vacci.
