Plasmid DNA (clone pNL4-3) that produces infectious HIV-1 virus particles in a wide variety of cells as described in the J Virol. 1986 Aug;59(2):284-91 and developed in the laboratory of Dr. Malcolm Martin at the National Institute of Allergy and Infectious Diseases.

A plasmid encodes human C-C motif chemokine receptor 3 (CCR3). It may contribute to the accumulation and activation of eosinophil and other inflammatory cells in the allergic airway.

The National Institute of Allergy and Infectious Diseases has invented three chlamydial vaccine technologies, which have shown promising preclinical efficacy. Chlamydia trachomatis infection is the most common sexually transmitted bacterial infection. If left untreated, chlamydia infection can lead to pelvic inflammatory disease and infertility. Chlamydia is also the leading cause of preventable blindness in the world. Despite increased surveillance, prevalence continues to increase, and the need to develop an effective chlamydial vaccine remains.

Rabies occurs in more than 150 countries and territories, resulting in at least 55,000 human deaths per year worldwide according to World Health Organization estimates. Rabies is a vaccine-preventable viral disease caused by numerous lyssaviruses that are found in a variety of animal species throughout the world. Rabies virus infects the central nervous system, causing disease in the brain with almost 100% mortality once clinical symptoms manifest.

Zika virus (ZIKV) can be passed from a pregnant woman to her fetus. Infection during pregnancy can cause microcephaly and other severe birth defects. Currently, there are no vaccines to prevent or medications to treat Zika infections.

Antibiotic resistance is one of the world's most pressing health concerns. ß-lactamases, such as carbapenemases, are enzymes produced by bacteria that provide resistance to multiple ß-lactam antibiotics (e.g., penicillins, cephamycins, and carbapenems) by breaking down the antibiotic molecules and deactivating their antibacterial properties. Carbapenems are broad-spectrum antibiotics often prescribed to treat serious infections in hospitalized patients, and infections with carbapenem-resistant Enterobacteriaceae (CRE) have become a challenge in healthcare settings.

The Zika virus (ZIKV) can be passed from a pregnant woman to her fetus. Resulting infection by this virus can cause early miscarriage and a pattern of severe birth defects in fetuses and infants. Therefore, a rapid diagnostic assay that can be performed throughout pregnancy in a clinical setting is vital for prenatal care of women living in areas where this virus may be transmitted.
