The invention features a method of vaccinating a mammal againstwhich includes the steps of: a) identifying a mammal at risk for the development of askin or soft tissue infection; and b) administering to said mammal an immunogenic amount of a vaccine that includes a polypeptide including an isolated agglutinin-like sequence (Als) 3 protein (Als3p), or an immunogenic fragment thereof, in a pharmaceutically acceptable medium.

Methods and compositions for vaccinating against

The invention provides a vaccine including an isolated Als protein family member having cell adhesion activity, or an immunogenic fragment thereof, with an adjuvant in a pharmaceutically acceptable medium. The invention also provides a method of treating or preventing hematogenously disseminated or mucocutaneous candidiasis. The method includes administering an immunogenic amount of a vaccine an isolated Als protein family member having cell adhesion activity, or an immunogenic fragment thereof, in a pharmaceutically acceptable medium. A method of treating or preventing disseminated candidiasis also is provided that includes administering an effective amount of an isolated Als protein family member having cell adhesion activity, or an functional fragment thereof, to inhibit the binding or invasion ofto a host cell or tissue. The Als protein family member can be derived from astrain selected from the group consisting ofandand the Als protein family member includes Als1p, Als3p, Als5p, Als6p, Als7p or Als9p. Also provided is a method of treating or preventinginfections. The method includes administering an immunogenic amount of a vaccine an isolated Als protein family member having cell adhesion activity, or an immunogenic fragment thereof, in a pharmaceutically acceptable medium.

Pharmaceutical compositions and methods to vaccinate against disseminated candidiasis and other infectious agents

The disclosure features isolated polypeptides of Hyr1. The disclosure further features vaccines and antibodies useful in treating or preventing candidiasis orinfections or both. Further disclosed are isolated polypeptides consisting of between 14 and 20 amino acids for vaccine preparation. The specific amino acid sequences of isolated polypeptides of Hyr1 are also disclosed.

Abloodstream infections cause significant morbidity and mortality in hospitalized patients. Filament formation and adherence to host cells are critical virulence factors of. Multiple filamentation regulatory pathways have been discovered, however the downstream effectors of these regulatory pathways remain unknown. The cell surface proteins in the ALS group are downstream effectors of the filamentation regulatory pathway. Particularly, Als1p mediates adherence to endothelial cells in vitro and is required for virulence. The blocking of adherence by the organism is described resulting from the use of a composition and method disclosed herein. Specifically, a pharmaceutical composition comprised of a gene, gene product, or specific antibody to the ALS gene family is administered as a vaccine to generate an immune response capable of blocking adherence of the organism.

Pharmaceutical compositions and methods to vaccinate against candidiasis

The invention provided Mucorales CotH polypeptides and encoding nucleic acid molecules. The Mucorales CotH polypeptides and encoding nucleic acids can be advantageously used to diagnose, treat or prevent fungal conditions, in particular mucormycosis.

Immunotherapy and diagnosis of mucormycosis using CotH

The present invention provides therapeutic compositions and methods for treating and preventing fungal disease or conditions including mucormycosis. The therapeutic methods and compositions of the invention include antibody, antibody fragment, siRNA and vaccine compositions having or directed against a GRP78 polypeptide or an antigenic fragment of the polypeptide.

Mammalian receptors as targets for antibody and active vaccination therapy against mold infections

The invention features HYR1 as a vaccine target and as a prophylactic strategy for combating disseminated candidiasis.

[object Object]

The present invention provides therapeutic compositions and methods for treating and preventing fungal disease or conditions including mucormycosis. The therapeutic methods and compositions of the invention include vaccine compositions having an FTR polypeptide or an antigenic fragment of the polypeptide; a vector including a nucleotide sequence that is substantially complimentary to at least 18 contiguous nucleotides of FTR sequence; an antisense; a small interfering RNA or an antibody inhibitor of FTR. The vaccine compositions of the invention can further include an adjuvant.

Abloodstream infections cause significant morbidity and mortality in hospitalized patients. Filament formation and adherence to host cells are critical virulence factors of. Multiple filamentation regulatory pathways have been discovered, however the downstream effectors of these regulatory pathways remain unknown. The cell surface protein, Als1p, is a downstream effector of the filamentation regulatory pathway and is regulated by Efg1p. Als1p mediates adherence to endothelial cells in vitro and is required for virulence. The blocking of adherence by the organism is described resulting from the use of a composition and method disclosed herein. Specifically, a pharmaceutical composition comprised of a gene product from the ALS1 gene family is administered as a vaccine to generate an immune response capable of blocking adherence of the organism.
