Novel Peptide of <em>Streptococcus pneumoniae</em> Surface Adhesion A (PsaA) Protein Associated with Adherence and Uses Thereof – for Vaccine Candidate, Therapeutic and Diagnostic Development

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.

The CDC 2009 Influenza A H1N1 (Flu) Pandemic Real-time RT-PCR Panel including Pandemic Influenza A and Pandemic H1 Assays

CDC researchers have developed probes and primers for detecting the 2009 pandemic influenza A H1N1 virus in patient samples using real-time reverse transcription-polymerase chain reaction (rRT-PCR) methods. These primers and probes were originally developed in 2009 and were cleared by the FDA as part of a domestic human diagnostic testing panel in June 2010. These were also updated to increase specificity and/or sensitivity of the detection methods.

New Anti-Influenza Virus Neuraminidase 9 (N9) Monoclonal Antibody – for Prevention or Treatment of H7N9 Influenza (Flu) A with Less Likelihood of Drug Resistance

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.

Real-time PCR Detection of <em>Streptococcus pneumoniae</em> with High Sensitivity and Specificity

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.

One-Step Random Amplification Method to Detect Extremely Low Input Nucleic Acids for Virome, Microbiome, and Metagenomics in Clinical and Biological Specimens

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.

Therapeutic and Diagnostic Targets for Severe RSV Infection

Respiratory Syncytial Virus (RSV) infects nearly all children by their second birthday. RSV usually causes mild respiratory illness, however, a subset of patients experience severe infection that require hospitalization. Successful host defense against viral pathogens requires rapid recognition of the virus and activation of both innate and adaptive immunity. Toll-Like Receptors (TLRs) are responsible for mounting an innate immune response and genetic variations within TLRs modulate severity of infection.

Local Magnetization Spoiling Using a Gradient Insert for Reducing the Field of View in Magnetic Resonance Imaging

The present invention provides a method and device for eliminating alias artifacts encountered in MRI when the field of view is made smaller than the subject being imaged. Significant advantages accrue from reducing the field of view to a smaller region of interest. These include reduced imaging time, increased spatial and temporal resolution, and less susceptibility to motion artifacts. The device operates by dephasing the magnetic resonance signal in regions away from the region of interest by means of a gradient insert.

Assay for Predicting the Time of Onset of Niemann-Pick Disease Type C (NPC)

Niemann-Pick Disease, type C (NPC) is a rare, autosomal recessive, neurodegenerative disease. Approximately 95% of patients with NPC have mutations in NPC1, a gene implicated in intracellular cholesterol trafficking. Mutation of NPC1 causes intracellular accumulation of unesterified cholesterol in late endosomal/lysosomal structures and marked accumulation of glycosphingolipids, especially in neuronal tissue. Thus, NPC patients generally present with hepatosplenomegaly (enlargement of liver and spleen) and neurological degeneration.

Codon-Optimized Gene Therapy for Niemann-Pick Disease Type C

Niemann Pick Disease Type C (NPC) is a rare and fatal, autosomal recessive, neurodegenerative disease that can present in infants, children, or adults. Most patients with NPC have mutations in NPC1, a gene implicated in intracellular cholesterol trafficking, which results in intracellular accumulation of unesterified cholesterol in late edosomal/lysosomal structures and of glycosphingolipids, especially in neuronal tissue. No curative therapy exists at present.

Newcastle Disease Virus-Like Particle Displaying Prefusion Stabilized SARS-CoV-2 Spike and Its Use

SARS-CoV-2 has resulted in a global pandemic, sparking urgent vaccine development efforts. The trimeric SARS-CoV-2 spike stabilized in its prefusion conformation by the addition of 2 proline mutations (“SARS-CoV-2 S2P”) is the antigenic basis of SARS-CoV-2 vaccines that are currently authorized for use in the United States.
