Over the past decade, Staphylococcus epidermidis has become the most prevalent pathogen involved in nosocomial infections. Usually an innocuous commensal microorganism on human skin, this member of the coagulase-negative group of staphylococci can cause severe infection after penetration of the epidermal protective barriers of the human body. In the U.S. alone, S. epidermidis infections on in-dwelling medical devices, which represent the main type of infection with S. epidermidis, cost the public health system approximately $1 billion per year. Importantly, S.

Concerns that variola (smallpox) virus might be used as a biological weapon have led to the recommendation of widespread vaccination with vaccinia virus. While vaccination is generally safe and effective for prevention of smallpox, it is well documented that various adverse reactions in individuals have been caused by vaccination with existing licensed vaccines. Vaccinia immune globulin (VIG) prepared from vaccinated humans has historically been used to treat adverse reactions arising from vaccinia immunization.

The four dengue virus (DENV) serotypes (DENV-1 to DENV-4) are the most important arthropod-borne flaviviruses in terms of morbidity and geographic distribution. Up to 100 million DENV infections occur every year, mostly in tropical and subtropical areas where vector mosquitoes are abundant. Infection with any of the DENV serotypes may be asymptomatic or may lead to classic dengue fever or more severe dengue hemorrhagic fever (DHF) and dengue shock syndrome (DSS), which are increasingly common in the dengue endemic areas.

Chlamydia trachomatis is an obligate intracellular bacterial pathogen that colonizes and infects oculogenital mucosal surfaces. The organism exists as multiple serovariants that infect millions of people worldwide. Ocular infections cause trachoma, a chronic follicular conjunctivitis that results in scarring and blindness. The World Health Organization estimates that 300–500 million people are afflicted by trachoma, making it the most prevalent form of infectious preventable blindness.

The catalytic subunit of the DNA-dependent protein kinase complex (DNA-PKcs) has been shown to be important in DNA repair and VDJ recombination in lymphocytes. The inventors have discovered that DNA-PKcs also plays novel, important roles in energy regulation and neurological function. The inventors observed that mature DNA-PKcs-deficient mice (also known as SCID mice) have a lower proportion of fat, resist obesity, and have significantly greater physical endurance than wild-type control mice, particularly with increasing age.

HIV Gag has been included in nearly all HIV vaccines entering clinical trials because of its importance in SIV models and its correlation with protection in HIV-infected long-term non-progressors. However, HIV Gag has proven less immunogenic than Env in phase I clinical trial studies. Through sequence comparison, two regions in HIV Gag have been identified as contributing to the decreased immunogenicity observed for HIV Gag. Replacement of these regions with corresponding SIV sequences significantly increased the resulting T-cell response to HIV Gag in mice.

This invention relates to improved methods of preparing Bacillus anthracis protective antigen (PA) for use in vaccines. PA is a secreted, non-toxic protein with a molecular weight of 83 KDa. PA is a major component of the currently licensed human vaccine (Anthrax Vaccine Adsorbed, AVA).

Available for licensing and commercial development are compositions and methods for the treatment and inhibition of Methicillin-resistant Staphylococcus aureus (MRSA), a dangerous human pathogen. The invention concerns immunogenic peptides that can be used to induce protective immunity against MRSA, including phenol-soluble modulin (PSM) peptides.

Ixodes scapularis is a blood-sucking tick and the principal vector of Lyme disease, a spirochetal illness caused by Borrelia burgdorferi and now the most common vector-borne infection in the United States; more than 50,000 cases have been reported during the last ten years. The salivary gland of I. scapularis has a number of pharmacologically active molecules that help the tick to successfully feed on blood, such as inhibitors of complement system, in addition to coagulation and platelet aggregation inhibitors.

Dengue virus is a positive-sense RNA virus belonging to the Flavivirus genus of the family Flaviviridae. Dengue virus is widely distributed throughout the tropical and semitropical regions of the world and is transmitted to humans by mosquito vectors. Dengue virus is a leading cause of hospitalization and death in children in at least eight tropical Asian countries.
