Streptococcus pneumoniae (S. pneumonia), bacteria commonly referred to as pneumococcus, are a significant cause of disease resulting in 1.5 million deaths every year worldwide according to the World Health Organization. The major types of pneumococcal disease are pneumonia (lung infection), bacteremia (bloodstream infection), and meningitis (infection of the tissue covering of the brain and spinal cord). Less severe pneumococcal illnesses include ear and sinus infections.

H7N9 influenza viruses are predominately avian (bird) pathogens, however, since 2013, they have infected more than 1500 humans with a mortality rate of nearly 40% in confirmed cases. H7N9 viruses continue to be a threat to public health. Treatment for people infected with H7N9-subtype influenza A (H7N9) commonly includes the use of drugs that inhibit neuraminidase, a protein found on the virus’ surface. However, like other influenza viruses, H7N9 can become resistant to these drugs.

Mycoplasma pneumoniae (M. pneumonia) can cause several different types of infection including chest colds and pneumonia. M. pneumoniae is a leading cause of community-acquired pneumonia. People of all ages are at risk for getting M. pneumonia infection, but it is most common among young adults and school-aged children. Current methods of detecting this agent are laborious and time consuming, so testing is not usually performed. However, knowing whether someone has M. pneumoniae infection is important for choosing the right antibiotic for treatment.

The molecular imaging technique of positron emission tomography (PET) is an increasingly important tool in biomedical research and in drug discovery and development. Many small molecule drugs and potential PET radiotracers carry trifluoromethyl (CF₃) groups. Because CF₃ groups are generally considered to be metabolically stable, there is a strong interest in developing drugs with these groups.

Streptococcus pneumoniae is the leading cause of community-acquired pneumonia and is also a frequent cause of bloodstream, brain and spinal cord, ear, and sinus infections. According to 2015 CDC data, an estimated 900,000 Americans get pneumococcal pneumonia each year and approximately 5-7% die from it annually. Accurate diagnosis and early treatment are important for improving patient outcomes.

This technology is directed towards a potential treatment for a new disease, CHAPLE (Complement Hyperactivation, Angiopathic thrombosis, and Protein-Losing Enteropathy), identified by NIAID researchers. CHAPLE is associated with GI symptoms and vascular thrombosis and is caused by loss-of-function variants in the gene encoding the complement regulatory protein CD55. The disease is caused by enhanced activation of the complement pathway and complement-mediated induction of intestinal lymphangiectasia and protein-losing enteropathy.

This technology is a set of influenza virus enrichment probes developed to increase the sensitivity of sequence-based, universal detection of all influenza viruses. This universal influenza enrichment probe set contains a unique set of 46,953 biotin-labeled, RNA probes, each 120 base-pairs long, that can be used to enrich for any influenza sequences without prior knowledge of type or subtype.

The technology addresses treatment options for diseases such as sickle-cell and thalassemia. Traditionally, such beta-globinopathies are treated through bone marrow transplantation. However, this method is limited due to high treatment costs and finding a matched-donor. This relies on increasing fetal hemoglobin to potentially cure the disease. NIH inventors have identified a protein called Rio-Kinase 3 (RIOK3), that inhibits the production of fetal hemoglobin. Their work shows that inhibiting RIOK3 increases the production of fetal hemoglobin.

Clinical and biological specimens often contain microbial nucleic acid in extremely low quantities, presenting a significant challenge for the detection of viral and bacterial pathogens. This also prevents direct sequencing of non-culturable samples using next-generation sequencing (NGS). Currently, NGS library preparation on most platforms requires 0.1 ng to 10 µg of DNA or cDNA, while microbial or viral nucleic acids in clinically relevant specimens, such as blood, serum, respiratory secretions, cerebral spinal fluid, and stool, often contain less than 0.1 ng.

Anthrax, whether resulting from natural or bioterrorist-associated exposure, is a constant threat to human health. Bacillus anthracis is the causative agent of anthrax. It is surrounded by a polypeptide capsule of poly-gamma-D-glutamic acid (gamma-D-PGA), which is essential for virulence, is poorly immunogenic and has anti-phagocytic properties. Antibodies to the capsule have been shown to enhance phagocytosis and killing of encapsulated bacilli.
