Real-Time PCR Assay for HIV-1 Subtype Diagnosis and Global Surveillance of Drug Resistance

CDC researchers have developed a patented set of RT-PCR and sequencing primers based on HIV-1 group M sequences. Evaluation of the primers using samples collected around the world demonstrated broad detection capacity for multiple HIV-1 group subtypes and predominant circulating recombinant forms. Commercially available HIV-1 drug resistance (HIVDR) genotyping assays are expensive and have limited ability to detect non-B subtypes. This optimized assay is broadly sensitive in genotyping HIV-1 group M viral strains and more sensitive than other assays in detecting mixed viral populations.

CDC Mosquito Trap for Control and Surveillance of Mosquitoes Including Carriers of Zika & Other Viruses

Mosquitoes are responsible for spreading many viruses that can make people sick, including dengue, Zika, chikungunya, yellow fever, and more. The Centers for Disease Control and Prevention's (CDC's) new autocidal gravid ovitrap (AGO) mosquito trap is an inexpensive, simple-to-assemble, and easy-to-maintain trap that targets female mosquitoes looking for a place to lay eggs. The current trap model stands 18 inches (45cm) tall and is made of a 5-gallon (18L) bucket. The AGO trap's unique design lures mosquitoes by using water and an all-natural, organic hay attractant.

Monoclonal Antibody to Detect the Antiretroviral Drug Emtricitabine – for HIV Drug Adherence Monitoring

The U.S. Food and Drug Administration and World Health Organization (WHO) approved the antiretroviral drug emtricitabine (FTC)/ tenofovir disoproxil fumurate (TDF) combination for HIV pre-exposure prophylaxis (PrEP) in high risk populations. Efficacy of PrEP depends strongly on adherence to taking the FTC/TDF pill daily. In the US, the Centers for Disease Control and Prevention (CDC) estimates that 1.2 million Americans will benefit from PrEP. FTC is also a key component of antiretroviral therapy (ART) regimens of HIV-infected persons and significantly associated with adherence.

Monoclonal Antibodies that Bind Zika Virus Envelope Protein for Zika Diagnostics and Research

Zika virus infection during pregnancy can cause microcephaly and other severe birth defects. The CDC Zika MAC-ELISA (IgM antibody capture enzyme-linked immunosorbent assay) currently used for diagnosis detects antibodies produced to fight a Zika virus infection. However, reactivity of flavivirus antibodies (from exposure to other mosquito-borne infections such as dengue or West Nile virus) can complicate the interpretation of these results.

Methods to Regulate Biofilm Development to Prevent Infection on Indwelling or Implantable Medical Devices

Formation of biofilms (microorganisms) on medical devices is a common cause of infection and device replacement. For example, biofilm formation on urinary catheters is associated with the development of catheter-associated urinary tract infections (CAUTI), and recent studies indicate that approximately 9% of HAIs stem from CAUTI. Urinary catheters are also thought to be one of the largest reservoirs of nosocomial antibiotic-resistant pathogens. The related increases in patient morbidity, mortality, and costs with CAUTI are substantial.

High-throughput assay for detection of rabies neutralizing antibodies

According to 2010-2014 World Health Organization (WHO) research, dog-transmitted human rabies was present or suspected in 150 countries and territories worldwide. Domestic dogs were the most common reservoir of the rabies virus in these countries, and more than 99% of human deaths were caused by dog-transmitted rabies. Rabies is 100% preventable in dogs with appropriate administration of vaccines.

Diagnostic Assay with Modified Cardiolipin for Detecting Active Syphilis Infections

Syphilis is a sexually transmitted infection that remains a global health threat. The World Health Organization estimates that more than 12 million new cases are reported in adults annually worldwide. Syphilis rates are rising domestically as well. The rapid plasma reagin (RPR) test (including automated version) and the Venereal Disease Research Laboratory (VDRL) test are commercially available and used to detect/screen active infection.

Cardiolipin Modification for Immunoassay Detection of Syphilis

Syphilis is a sexually transmitted disease (STD) that remains a global health threat. Syphilis rates in the United States have also been increasing. Left untreated, syphilis infection can span decades and have serious complications including blindness, dementia and paralysis. Syphilis in pregnancy causes prematurity, low birthweight, neonatal death, and infections in newborns. Improvements in syphilis detection are needed to facilitate early diagnosis of active infections and monitor treatment with antibiotics.
