Novel Enzyme-Based Immunoassay for Simultaneous Detection of Hepatitis C Virus Antigen and Antibody in Human Serum or Plasma

CDC scientists have developed a novel enzyme immunoassay for the simultaneous detection of hepatitis C virus (HCV) core antigen and circulating HCV antibodies. Serological testing procedures for HCV circulating antibodies are well established. There is, however, a window of time between HCV infection and seroconversion that generates an opportunity...

Multiplex Assay for Rapid Salmonella Serotyping from Human, Animal, Food and Environmental Sources

CDC researchers have developed a bead-based nucleic acid assay for serotyping members of the Salmonella genus; this assay will identify serotypes for approximately 95% of all human-obtained Salmonella isolates in the United States. Presently, production and quality control for the more than 250 antisera required to cover the >2,500 known serotypes using...

Simple, Field-Usable Fluorescence-Based Isothermal LAMP Assay for the On-Site Diagnosis of Malaria

CDC researchers have developed improved Loop-Mediated Isothermal Amplification (LAMP) assays for the nucleic acid-based diagnosis of malaria in field settings. The approach employs Plasmodium genus-specific LAMP primers and a portable tube scanner to run the LAMP reaction and measure fluorescence signal (e.g., SYBR green) as a measure of DNA amplification...

Compositions and Methods for Improved Lyme Disease Diagnosis

This CDC-developed technology entails novel compositions and methods related to the diagnosis of Lyme disease. Lyme disease, caused by the Borrelia burgdorferi bacterium, is the most common tick-borne infectious disease in the US and Europe. Diagnosis of Lyme disease is particularly challenging as symptoms often appear long after exposure. At present,...

Human Influenza Virus Real-time RT-PCR: Detection and Discrimination of Influenza A (H3N2) Variant from Seasonal Influenza A (H3N2) Viruses, Including H3v and Seasonal H3 Assays

This invention relates to methods of rapidly detecting influenza, including differentiating between type and subtype. CDC researchers have developed a rapid, accurate, real-time RT-PCR assay that has several advantages over culture and serological tests, which require 5 to 14 days for completion; this assay can also be easily implemented in kit form....
