Simple, Rapid, and Sensitive Real-Time PCR Assays for Detecting Drug Resistance of HIV

This novel assay features real-time PCR reagents and methods for detecting drug-resistance related mutations in HIV, for newly diagnosed patients and those individuals currently receiving antiretroviral therapies. As the use of antiretroviral compounds to treat HIV infection proliferates, viruses adapt and evolve mutations limiting the efficacy of these drugs and disrupting the success of treatment.

Select M. tuberculosis Peptides as Mucosal Vaccines Against Pulmonary Tuberculosis

This CDC-developed technology relates to novel vaccines or boosters directed against pulmonary tuberculosis. There is currently only a single vaccine against tuberculosis, the (Bacillus Calmette-Guérin) BCG vaccine. Reports suggest widely variable effectiveness for the BCG vaccine and that BCG administration has very limited success against prevention of the primary pulmonary form of the disease.

A Bias-free Sampling and Collection Trap for Resting Mosquitoes

This CDC developed collection device is a small (approximately 1 cubic foot) open-sided container that attracts mosquitoes seeking a daytime resting location. The container is dark-colored and constructed of molded wood-fiber or recycled, high-density plastic. Mosquitoes that enter the dark space of the container are aspirated through a battery-powered fan into a collection receptacle. The receptacle is especially attractive to Culex and Anopheles mosquitos' vectors of West Nile Virus and malaria parasites, respectively.

Use of Detector Response Curves to Optimize Settings for Mass Spectrometry

This CDC developed optimization technology allows one to characterize the behavior of the coefficient of variation (CV) for a range of mass spectrometer machine settings. Surface-enhanced laser desorption/ionization (SELDI) and matrix-assisted laser desorption/ionization (MALDI) are used for the early detection of numerous diseases, for example cervical cancer . A critical step in the analytical process is the optimization of experiment and machine settings to ensure the best possible reproducibility of results, as measured by the CV.

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.

Multiplexed Immunoassay for Rapid Serological Diagnosis of a Specific Viral Infection in Clinical Samples

CDC researchers have developed a multiplexed diagnostic assay for sensitive detection and distinction between viral group members based on the presence/absence of infection-generated antibodies within a clinical serum sample. For example, this assay can be used for rapid discrimination of a clinical unknown as specifically a West Nile or St. Louis encephalitis viral infection. This is particularly beneficial as these two viruses are typically difficult to distinguish by standard serological assays.

This new technique uses microsphere/microbead-based flow-analysis as a platform.

Entangling/Entrapping Synthetic Setae for Control of Insects and Other Pests

In nature, some beetle larvae possess specialized barbed hastate setae that serve as an entanglement defense mechanism and incapacitate other insects. CDC researchers have developed synthetic setae for control and entrapment of insects and other pests. While smaller synthetic setae can trap mosquitoes and small insects, larger “macro” setae can be used for entrapment of bats, rodents, etc. Once used, the setae can be "reset" by a vigorous shaking of the fabric.

Real-time RT-PCR Assay for the Detection of Rift Valley Fever Virus in Humans and Livestock

A quantitative RT-PCR-based assay has been developed to rapidly detect all known strains of Rift Valley fever virus (RVFV). RVFV infections occur in both humans and livestock animals resulting in significant mortality and economic loss. Upon outbreak, RVFV has been known to cause devastating loss among livestock (primarily sheep and cattle) with outbreaks characterized by sweeping "abortion storms" and elevation newborn animal mortality approaching 100% in affected areas. The CDC-developed assay is capable of detecting and quantifying RVFV infection in both human and veterinary samples.

Universal Diagnostic Assay for Detection and Identification of Poxviruses in Clinical Samples

CDC researchers have developed an assay for detection and diagnosis of poxviruses within clinical samples or from lab culture-systems. The assay specifically targets chordopoxviruses (except avipoxviruses) for PCR-based identification; an improvement upon the current standard of cell culturing methodologies. Individual chordopoxvirus species can cause disease in humans (e.g., vaccinia, cowpox, monkeypox/Molluscum contagiosum) and animals (e.g., sheeppox, myxoma, swinepox, mule deer pox, tanapox/Orf virus, Bovine popular stomatitis virus).
