Description of Technology: B. burgdorferi-infected ticks can cause Lyme disease in mammalian hosts. This technology relates to the use of B. burgdorferi outer surface proteins (BBA64 and BBA66) as Lyme disease vaccine candidates. In vivo animal studies demonstrate these outer surface proteins inhibit tick-to-host B. burgdorferi transmission. Presently, there is no vaccine approved for Lyme disease.
This technology may also be used for creation of antibodies directed against B. burgdorferi. Thus, this innovation may prevent B. burgdorferi infection by passive immunity and provide new diagnostic tools, which will allow early intervention.

Description of Technology: CDC scientists have developed a one-step TaqMan quantitative/real-time reverse transcription-polymerase chain reaction (qRT-PCR) assay for detecting hepatitis D virus (HDV) RNA. Additionally, a quantifiable synthetic RNA control to determine viral load has been created.
HDV is an operatively defective virus that requires hepatitis B virus (HBV) surface antigen (HBsAg) for its assembly. Compared to individuals infected with HBV alone, individuals infected with both HDV and HBV Start Printed Page 4731viruses present with more severe hepatitis, progress to liver disease more quickly, and have a higher mortality rate. Currently, there are no regulated tests available for detection and quantification of HDV RNA. This assay directly addresses this unmet need and has been validated with clinical samples of HDV genotypes 1 and 3. It has the potential to detect all eight HDV genotypes.
Development of a commercial nucleic acid assay for diagnosis of current hepatitis D virus (HDV) infection
Testing of individuals infected with hepatitis B and/or liver disease
Rapid, accurate, inexpensive and stable
Unique RNA transcript for this assay can be successfully used as a quantitative standard
Current anti-HDV antibody assay identifies individuals exposed to HDV, but cannot identify current infection
Easily adapted for inclusion in a hepatitis testing kit, especially when paired with a hepatitis B diagnostic

Description of Technology: This invention relates to a genetically modified hemorrhagic fever virus that can be used as an effective live vaccine agent. Hemorrhagic fever evades the human immune response using the viral ovarian tumor domain (vOTU) protease, which inhibits critical host-immunity functions. The present genetically modified virus has a vOTU protease with decreased ability to remove ubiquitin (Ub) and ISG15 tags from proteins in cells it infects. Thus, the virulence is reduced, creating an immunogenic and non-pathogenic virus for use as a live vaccine against Crimean-Congo hemorrhagic fever (CCHF) virus. Unlike strains with complete ablation of the vOTU protease, the present modified virus retains enough activity for replication in a human cell line, making vaccine production possible. This technology may be used to create vaccines or therapeutics for other nairoviruses, including the Dugbe, Hazara, and Nairobi sheep disease viruses.
Potential Commercial Applications: Development of vaccines or therapeutics for CCHF virus and other nairoviruses, including Dugbe, Hazara and Nairobi sheep disease viruses
Increased safety for CCHF laboratory research (Biosafety Level 2)
Use of human cell lines allows large-scale manufacturing of vaccines
vOTU domain-disruption may be used to develop vaccines for all nairovirus viruses affecting humans and/or livestock

Description of Technology: The critical feature of this technology is the Evelyn-Rokitnicki-Abelseth (ERA) rabies whole genome DNA sequence. With the availability of the entire rabies genome, a recombinant vaccine can be developed using reverse genetics. Using this technology, CDC researchers have developed a recombinant, live-attenuated vaccine shown to confer protection against lethal doses of live, street-rabies virus in multiple survival studies. This vaccine offers better protection than traditional inactivated vaccinations, as demonstrated in co-infection studies. Further, a single intramuscular vaccination with the CDC's attenuated-virus was sufficient for survival of 100% of hamsters and mice following lethal challenge.

Description of Technology: CDC researchers have developed a single-tube, real-time PCR assay for the simultaneous detection of three bacterial respiratory pathogens (Mycoplasma pneumoniae, Chlamydiophila pneumoniae and Legionella spp.). The assay has an internal control testing for presence of human DNA. This four-plex real-time PCR assay could potentially become a routine screening test for patients with respiratory illness. Ninety four clinical specimens (in a 96-well format) can be tested at once. This assay is non-invasive, rapid and cost-effective. It has the potential for point-of-care applications in population-based pneumonia surveillance.

Description of Technology: The CDC developed a real-time reverse transcription polymerase chain reaction (RT-PCR) Taqman assay and an RT-semi nested PCR (RT-snPCR) assay for the detection of parechoviruses. Similar to enteroviruses, parechoviruses are responsible for gastrointestinal, respiratory and central nervous system infections. All tests target conserved regions in the 5′nontranslated region (5′NTR) of the parechovirus genome and share forward and reverse primers. The Taqman probe and RTsnPCR nested primer target the same conserved site but vary in length. Both assays detect all known human parechoviruses (PPeV) and Ljungan viruses (LV), unlike other published parechovirus 5′NTR assays, which only detect a limited number of PPeV types. Both assays are more sensitive than current methods (culture and multiple, single-serotype nucleic acid amplification assays) and may be used to test isolates or original clinical specimens.

Description of Technology: Legionnaires' disease is caused by a type of bacteria called Legionella. CDC scientists have developed a real-time multiplex PCR assay for diagnosis and identification of Legionella strains. The assay consists of five sets of primers (targeting L. bozemanii, L. dumoffii, L. feeleii, L. longbeachae, or L. micdadei) and corresponding probes. Each probe is labeled with a different fluorophore which allows the detection of a particular strain in a single tube reaction. Using this assay format, the presence of any one of the five pathogenic non-pneumophila strains of Legionella can be detected rapidly from clinical or environmental samples. Rapid and sensitive identification enables initiation of appropriate antibiotic therapy and identification of the source of bacteria so that proper public health responses may occur.
Potential Commercial Applications: Rapid and real-time assay to detect the presence of clinically relevant non-pneumophila Legionella strains.
Currently available tests are time consuming and labor intensive.
This assay enables rapid identification and differentiation on clinically relevant non-pneumophila Legionella strains.
This assay can be used as a standalone confirmatory assay for the detection of common non-pneumophila Legionella species or as one of the valuable assays in conjunction with other standard assays.

Description of Technology: CDC researchers developed a simple target-specific isothermal nucleic acid amplification technique, termed Genome Exponential Amplification Reaction (GEAR). The method employs a set of four primers (two inner and two outer). The outer primer pair targets three specific nucleic acid sequences at a constant 60 °C, while the inner pair of primers accelerates and improves the sensitivity of the assay.
The GEAR technique is an improvement over loop-mediated isothermal amplification (LAMP) in three ways. First, the GEAR method uses two Tab primers which target three genomic regions (corresponding LAMP primers target four regions). Second, the GEAR method features complementary 5′ ends between the forward and reverse primers. Third, the GEAR method does not require a second set of outer primers (LAMP requires two outermost primers). Additionally, the GEAR isothermal method can be performed in a relatively inexpensive water bath or heating block, with detection of amplification products by fluorescence, thus making it suitable for low resource settings.

Description of Technology: 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. Individual proteins or peptides of the HRTLDV can also be used in other FDA-approved virus backbones to act as vaccines. Further, since HRTLDV targets the bone marrow, disclosed HRTLDV delivery vehicles may be used to deliver therapeutic agents to the bone marrow.

Description of Technology: CDC researchers have developed a 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. Further, commercially available HIV-1 drug resistance (HIVDR) genotyping assays Start Printed Page 4737are 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 TRUGENE® and ViroSeq® assays in detecting mixed viral populations. Additionally, this assay is useful in resource-limited settings where HIVDR surveillance is recommended to minimize the development and transmission of HIVDR.

Description of Technology: This Intranasal Dry Powder Inhaler (DPI), developed with Creare, Inc., allows low-cost delivery of powder vaccines. Nasal delivery has numerous advantages compared to traditional injected vaccines, including: (1) Safe, needle-less administration by minimally-trained staff or patient; (2) better protection due to mucosal and cross-protection; and (3) decreased biohazard waste. Further, dry powder aerosol vaccine delivery is superior to liquid aerosol delivery in a number of ways, including: (1) No dose reconstitution required; (2) highly thermostable and may not need cold chain storage; (3) costs less to store and transport; (4) improved efficacy through elimination of liquid spray nasal-dripping. This CDC-Creare invention is unique in that it is inexpensive and suitable for single-use applications, such as vaccination. It prevents the dose being deposited within the lower respiratory tract, improving safety. This delivery system has a broad range of potential applications including, but not limited to, childhood vaccination programs, self-administered therapeutics, and emergency biodefense.

Description of Technology: CDC researchers have developed recombinant lyssaviruses that can be used for the development of an improved, broad-spectrum vaccine against several rabies genotypes. Lyssaviruses are single-stranded RNA viruses that cause rabies and rabies-like diseases in mammals. Currently, there are commercially available vaccines that are considered to be effective against infections from a single viral phylogroup; however, these vaccines confer little or no protection against viruses outside of the phylogroup. The present recombinants have glycoprotein-encoding genes from at least two different lyssaviruses and can be used as pan-lyssaviral vaccines to provide protection against infection by multiple lyssavirus phylogroups.

Description of Technology: CDC scientists have developed a real-time PCR assay for diagnosing pneumococcal disease using amplification of the bacterial gene encoding pneumococcal surface adhesin A (PsaA). Pneumococcal isolation and identification is often complicated by (1) antimicrobial suppression of growth in culture and (2) contamination by normal flora alpha-streptococci. Further, pneumococcal detection by culture and serological methods can be time-consuming, relatively expensive, laborious and, ultimately, indeterminate. Sensitive and specific assays that can be completed quickly in the clinical laboratory are essential for early diagnosis and effective therapy. This RT-PCR assay provides a tool for quick and accurate diagnosis by physicians and health care technicians and may be useful in evaluating the efficacy of novel pneumococcal vaccines and therapeutics.

Description of Technology: In order to develop a simple detection assay for field use, CDC researchers cloned and sequenced the Taenia solium T24 diagnostic protein. The T24 sequences can be used to detect and diagnose T. solium infection or can be formulated into a pharmaceutical composition. T. solium is a species of tapeworm. Intestinal infection with T. solium is referred to as taeniasis. Many taeniasis infections are asymptomatic but may be characterized by insomnia, anorexia, abdominal pain and weight loss. Cysticercosis infection, which can be fatal, may develop if T. solium larvae migrate out of the intestine and form cysticerci in various body tissues. This technology may be used to develop a diagnostic, vaccine, or therapeutic for infection related to T. solium.

Description of Technology: CDC researchers developed a more efficient method of assessing rabies vaccine potency using an antigen-capture electrochemiluminescent (ECL) assay. This assay utilizes SULFO-NHS-Ester labeled murine monoclonal antibodies to quantify glycoprotein concentration, which is an indicator of vaccine potency. Currently, the potency of rabies vaccines is determined by the effective-dose (ED50) mouse study evaluation method, which is more than 50 years old. The labor-intensive ED50 evaluation method has high operating costs, extensive biosafety requirements, and requires the sacrifice of a large number of animals. CDC researchers have addressed these issues by developing a competitive in vitro antigen-capture assay that is rapid, highly robust, reproducible, flexible and much less expensive to implement than the traditional ED50-mouse study evaluation.

Description of Technology: This invention relates to methods and compositions for rapid detection of HIV nucleic acids in a biological sample. Specifically, it involves the use of the loop-mediated isothermal amplification (LAMP) for rapid detection of HIV-1 and/or HIV-2. The use of rapid HIV tests is highly attractive for screening of patient samples, especially in developing countries where resources are limited, because they are quick, easy to perform, and do not require any special equipment. Rapid tests for the identification of HIV antibody, however, will remain negative during the 4 to 5 week window post-infection and pre-seroconversion, necessitating the need for a diagnosis based on HIV nucleic acid.

Description of Technology: Mosquitoes are responsible for the transmission of a number of important zoonotic diseases, including dengue fever, malaria, and rift valley fever. The CDC-AGO (Autocidal Gravid Ovitrap) mosquito trap is a device that targets older female mosquitoes looking for a suitable place to lay eggs. This device is 45 centimeters tall with a 10-liter capacity to hold an attractant, such as water and decaying vegetation. The mosquitoes are captured by a nontoxic adhesive and eggs are collected on a hydrogel. The use of the hydrogel instead of a liquid prevents the larvae from hatched mosquito eggs from completing development.
Novel aspects of this technology are the use of non-toxic components and slow to dry hydrogel, as opposed to insecticide. While there are a number of chemical methods for controlling mosquitoes, these chemicals are always subject to the evolution of resistance from the mosquito population and, thus, there is a need for additional non-chemical control methods.

Description of Technology: CDC researchers have developed a real-time PCR assay for the detection of Neisseria meningitidis sodC within clinical specimens. The ability to detect all strains of N. meningitidis, regardless of individual serogroup, is the central innovation of this technology. Further, the assay is sensitive enough to detect even the very limited sample sizes of N. meningitidis that would typically be found in clinical specimens. This technology avoids potentially catastrophic false-negative results associated with current N. meningitidis carriage study testing methods. At least 16% of carried N. meningitidis lacks the ctrA gene, which is the current target of serogroup-based real-time PCR. N. meningitidis is the etiologic agent of epidemic bacterial meningitis and sepsis throughout the world and rapid detection of N. meningitidis infection is essential for patient well-being.

Description of Technology: Dengue hemorrhagic fever (DHF) is a severe, potentially deadly infection spread by mosquitos. CDC scientists have identified vitronectin as an important biomarker of DHF. They have shown vitronectin is significantly reduced in DHF and severe dengue infections when compared to dengue non-hemorrhagic fever patients. Presently, DHF is established by assessing antibody concentrations and other rule-of-thumb criteria, but often these assays can be difficult to interpret and lead to false conclusions. Establishing vitronectin levels provides a specific, novel biomarker for DHF, leading to increased accuracy in clinical diagnoses and improved patient outcomes.Start Printed Page 4743

Description of Technology: A specific and sensitive TaqMan-based real-time (rt) RT-PCR assay has been developed by CDC scientists for detection of noroviruses in clinical and environmental specimens. This assay can be implemented to rapidly detect and distinguish norovirus strains from genogroups I and II, which are responsible for the majority of human infections. Additionally, the assay is multiplexed with an internal extraction control virus (coliphage MS2) to validate the results of the assay. Since the virus cannot be grown in cell culture and enzyme immunoassays lack the necessary sensitivity, this technology is particularly useful.
