Nucleic Acid Assays for the Detection and Discrimination of Aspergillus Fungi Species within Biological Samples

This invention relates to assays for the detection and species-specific identification of Aspergillus fungi. Accurate clinical diagnosis of Aspergillus species has become increasingly important as certain species, such as A. terreus and A. fumigatus, are resistant to specific commonly employed antifungal compounds. Most contemporary fungal diagnostic methods are time-consuming and inaccurate.

Nucleic Acid-based Compositions and Methods for the Detection of Pathogenic Candida or Aspergillus Fungi Species

This invention pertains to the development of oligonucleotides for the rapid nucleic acid-based identification of Candida or Aspergillus fungi species in biological samples. This identification is accomplished by the targeting the internally transcribed spacer-2 (ITS2) region that are unique to various Candida species. The assay is sensitive, specific and rapid. Implementation of the technology will facilitate earlier specific diagnoses, and lead to better antifungal therapy implementation for infected patients.

Nucleic Acid-based Compositions and Methods for the Species-Specific Detection of Pathogenic Candida Fungi

This invention pertains to the development of oligonucleotides for the rapid nucleic acid-based identification of the Candida fungi species C. haemulonii, C. kefyr, C. lambica, C. lusitaniae, C. norvegensis, C. norvegica, C. rugosa, C. utilis, C. viswanathii, C. zeylanoides, C. dubliniensis, and C. pelliculosa within biological samples. This identification is accomplished by the targeting the internally transcribed spacer-2 (ITS2) region that are specific for each species.

Diagnostics, Vaccines, and Delivery-Vehicles Related to Novel Phlebovirus

This CDC invention relates to primers and probes that specifically hybridize with Heartland virus (HRTLDV), a unique member of the genus Phlebovirus. It further relates to polyclonal antibodies specific for HRTLDV proteins. Serological detection assays using HRTLDV nucleic acid molecules, proteins, probes, primers, and antibodies are provided. Importantly, the HRTLDV genome can be engineered using reverse genetics to be attenuated, allowing development of a vaccine for other viruses within the Phlebovirus genus or Bunyaviridae family.

SARS-CoV-2 Iinfection of Human Lung Epithelial Cells Triggers a Cell-Mediated Acute Fibrin Fibrosis

Scientists at NIAID have developed a method of treatment for virus-induced lung fibrosis using nebulized thrombin inhibitors. Since March 2020, the WHO estimates that 564 million people have been infected with SARS-CoV-2 world-wide. Lung fibrosis is a major factor associated with SARS-CoV-2 infections and can contribute to mortality. Additionally, severe SARS-CoV-2 cases can result in long-term pulmonary disease due to lung fibrosis. At present, attempts to treat lung fibrosis developed during a SARS-CoV-2 infection using intravenous heparin have been unsuccessful.

Autodock Vina Software Process for Efficient Large-Scale Cognate Ligand Screening

The invention pertains to software processes, additions, and docking approaches to Autodock Vina that speeds the rate and efficiency of analyzing ligand interactions with a receptor by cognate ligands and rewards conformations in the scoring algorithm for residue interactions that are based on the biological data. The score is multiplied by a weighting factor to control the degree of ligand-residue interactions that are considered. This multiplier is then added to the docking score for confirmation.

Novel Inactivated Zika Vaccine Candidate Based on Purified Wild-type Zika Virus — for Zika Vaccine and Diagnostic Assay Development

Zika virus (ZIKV) spreads to people primarily through bite by infected Aedes mosquitoes. ZIKV infection during pregnancy can cause stillbirths or affect the fetus by causing serious birth defects, such as microcephaly and other brain defects. Although uncommon, adults with ZIKV can also develop Guillain-Barre syndrome and other neurological disorders. According to the World Health Organization’s July 2019 report, a total of 87 countries and territories have had evidence of mosquito-borne transmission of ZIKV.

A Simple Colorimetric Assay for Anti-malarial Drugs Quality Assurance and Rapid, On-site Counterfeit Detection

This CDC assay aims to lessen the anti-malarial drug counterfeiting epidemic by testing for the artemisinin-type drugs (the active compound), through the use of a simple, inexpensive colorimetric test. Poor quality and counterfeit drugs pose an immediate threat to public health and undermine malaria control efforts, resulting in resistant-parasites and invalidates effective compounds, i.e.

Recombinant Polypeptides for Clinical Detection of Taenia solium and Diagnosis of Cysticercosis

CDC scientists have developed synthetic/recombinant polypeptides that can be used for the creation of inexpensive, high-quality cysticercosis diagnostic assays. Taenia solium is a species of pathogenic tapeworm. Intestinal infection with this parasite is referred to as taeniasis and it is acquired by ingestion of T. solium cysticerci found in raw and undercooked pork, or food contaminated with human or porcine excrement. Many infections are asymptomatic, but infection may be characterized by insomnia, anorexia, abdominal pain and weight loss.
