Mutated and/or truncated malarial circumsporozoite proteins (CSP) and associated nucleic acids that are more stable and highly expressed in mammalian cells are described. The mutated and/or truncated CSP and associated nucleic acids can be expressed to produce malaria vaccine antigens.

A method of immunizing a mammalian patient against infection by a bacterial pathogen involves administering a pertussis or Pseudomonas antigen to the mammalian patient. The pertussis antigen is least one of a chaperonin protein GroEL from Bordetella pertussis, or a fragment thereof; and an OmpA protein of Bordetella pertussis, or a fragment thereof. The Pseudomonas antigen is least one of a chaperonin protein GroEL from Pseudomonas aeruginosa, or a fragment thereof; and an OprF protein from Pseudomonas aeruginosa, or an OmpA-domain fragment thereof. The bacterial pathogen expresses a protein having at least 45% identity to the pertussis antigen. The bacterial pathogen may be a gram-negative bacteria. The bacterial pathogen may be a bacteria from a genus Escherichia, a genus Enterococcus, a genus Staphylococcus, a genus Klebsiella, a genus Acinetobacter, and a genus Enterobacter.

Methods of priming a Sus' immune system are disclosed. The methods comprise administering an effective amount of a Mycobacterial whole cell lysate to a Sus within an effective period of time after the Sus is born.

The invention relates to a method for treating protozoal gastrointestinal disorders in immunocompromised patients. It includes a method for the isolation of a factor from the milk of hyperimmunized animals in a substantially pure form, and to the use of said factor in combination with vitamins and minerals.

Provided herein are compositions and methods for the induction and/or proliferation of CD8+ T-cells. The disclosure also provides methods of treatment of diseases that can be treated by the induction and/or proliferation of CD8+ T-cells.

The present invention aims to provide a composition for promoting humoral immunity induction and a vaccine pharmaceutical composition that can be universally used for various antigens in inducing humoral immunity to antigens, contain a Th2 reaction promoter, and exerts a high humoral immunity inducing effect. The present invention relates to a vaccine pharmaceutical composition containing an antigen for humoral immunity induction and at least one Th2 reaction promoter.

This disclosure provides antibody fragments and isolated polypeptides comprising the antibody fragments that are useful as a therapeutic for those with an existing infection characterized by the formation of biofilms. Antibody fragments and isolated polypeptides comprising the antibody fragments can be administered to detect, treat, or prevent infection and/or remediate biofilms. Bacteria that cannot form functional biofilms are more readily cleared by the remainder of the host's immune system and/or traditional antibiotics.

The present disclosure provides use of Clostridium ghonii combined with a tumor angiogenesis inhibitor in preparing a pharmaceutical product for treating a tumor. The present disclosure further provides a drug for treating a tumor, where the drug includes active ingredients of Clostridium ghonii and a tumor angiogenesis inhibitor.

A transdermal delivery system of microneedles containing a bioactive material, comprising at least one layer of a support material; at least one biodegradable needle associated with the support material, each needle comprising at least one biodegradable polymer and at least one sugar, wherein each biodegradable needle is hollow and is adapted to retain a bioactive material.

The present invention provides vaccine or immunogenic compositions comprising novel antigens derived from the equine strain of influenza H3N8. These proteins and specific immunogenic domains are effective as primary universal influenza antigens. The disclosed vaccines or immunogenic compositions are highly effective in inducing HA specific antibodies reactive to different influenza viruses, mucosal and systemic immune responses, and cross-protection regardless of influenza virus subtypes. In some embodiments, the vaccine is cross-protective against two or more (e.g., 2, 3, 4, 5, or 6) subtypes of influenza with or without the use of an adjuvant.
