Multiple Antigenic Peptide Assays for Detection of HIV and SIV Type Retroviruses

   Description of Technology: CDC scientists have developed multiple antigenic peptide immunoassays for the detection of human immunodeficiency virus (HIV) and/or simian immunodeficiency virus (SIV). HIV can be subdivided into two major types, HIV-1 and HIV-2, both of which are believed to have originated as result of zoonotic transmission. Humans are increasingly exposed to many different SIVs by wild primates. For example, human exposure to SIVs frequently occurs as a consequence of the bush meat hunting and butchering trade in Africa. Human exposure to SIVs may lead, or may have already led, to transmission of SIVs with potential for new virus induced immunodeficiency epidemics. Unfortunately, new cases of zoonotic virus transmission may go undetected because of the lack of SIV-specific tests. Thus, there is the potential to compromise the safety of the blood donor supply system and seed a new HIV-like epidemic. This invention addresses these problems by providing a way to test all primates for the many divergent lentivirus strains to identify primary infections and prevent secondary transmission.

   Potential Commercial Applications:

* Detection and differentiation of HIV-1, HIV-2 and SIVs

* HIV/SIV surveillance

* SIV/HIV/AIDS research

* Sero-monitoring of potential zoonotic transmissions

* Blood-donation supply assurance tool

   Competitive Advantages:

* Fills an unmet need for SIV-specific tests

* Sensitive and specific

* Easily adapted to kit/array format

* Research indicates greater sensitivity than standard HIV enzyme immunoassays (EIAs) for detecting SIV infections

   Development Stage: In vitro data available.

Auscultatory Training System and Telemedicine Tool with Accurate Reproduction of Physiological Sounds

   Description of Technology: This CDC developed auscultatory training apparatus includes a database of prerecorded physiological sounds (e.g., lung, bowel, or heart sounds) stored on a computer for playback. Current teaching tools, which utilize previously recorded sounds, suffer from the disadvantage that playback environments cause considerable distortion and errors in sound reproduction. For example, to those trainees using such systems, the reproduced respiratory sounds do not "sound" as if they are being generated by a live patient. Moreover, the aforementioned playback distortions often make it difficult for the listener to hear and interpret the subtleties of a recorded respiratory maneuver.

   This device includes a software program that allows a user to select prerecorded sounds for playback. The program will also generate an inverse model of the playback system in the form of a digital filter. The inverse model processes a selected sound to cancel the distortions of the playback system so the sound is accurately reproduced. The program also permits the extraction of a specific sound component from a prerecorded sound so only the extracted sound component is audible during playback. In addition to the obvious role of a teaching tool for medical professionals, this invention could have applications as a diagnostic screening and/or telemedicine tool.

   Potential Commercial Applications:

* Auscultatory training for health care professionals

* Telemedicine tool

* Diagnostic screening comparison and control

   Competitive Advantages:

* Accurate, realistic reproduction of in situ physiological sounds

* Apparatus features noise-cancelling filter to eliminate ambient distortion artifacts during playback

* Device is extremely portable

* Allows for isolation and playback of specific elements of a recording

   Development Stage:

* In situ data available (on-site)

* Prototype

Enterovirus Molecular Diagnostic Test Kit

   Description of Technology: CDC researchers have developed a reverse transcription/semi-nested polymerase chain reaction (RT-snPCR) assay for diagnosis of enterovirus infections within clinical specimens. Clinical laboratories currently identify enteroviruses by virus isolation and subsequent virus neutralization tests, or serological assays. In addition to being time consuming, these approaches are labor, cost and material intensive.

   The enterovirus molecular diagnostic test is prepared in a kit form, consisting of three reagent preparations (three separate test steps), to which a technician adds enzymes and RNA extracted from a clinical specimen. This format is amenable to commercial manufacturing processes. The assay primers were designed for broad specificity and amplify all recognized enterovirus serotypes. In the course of assay development, PCR products have been successfully amplified and sequenced from cerebrospinal fluid, nasopharyngeal swabs, eye swabs, rectal swabs and stool suspensions, allowing for unambiguous identification of the infecting virus in all cases. This assay will be useful for the diagnosis of numerous common illnesses, such as foot-and-mouth disease, respiratory illness, conjunctivitis, neonatal illness, and myocarditis, among several others.

   Potential Commercial Applications:

* Detection and identification of enterovirus infections, such as foot-and-mouth disease

* Diagnostic evaluations of respiratory or neonatal illnesses

* Enterovirus surveillance programs for humans and animals/livestock

   Competitive Advantages:

* Ready for commercialization

* Easily adaptable to kit form

Generation of Artificial Mutation Controls for Diagnostic Testing

   Description of Technology: This technology relates to a method of generating artificial compositions that can be used as positive controls in a genetic testing assay, such as a diagnostic assay for a particular genetic disease. Such controls can be used to confirm the presence or absence of a particular genetic mutation. The lack of easily accessible, validated mutant controls has proven to be a major obstacle to the advancement of clinical molecular genetic testing, validation, quality control (QC), quality assurance (QA), and required proficiency testing. This method provides a consistent and renewable source of positive control material, as well as an alternative to patient-derived mutation-positive samples.

   Potential Commercial Applications: Generation of positive controls for molecular genetic tests, particularly for tests to detect cystic fibrosis.

   Competitive Advantages:

* Positive controls can be included in new kits or packaged with pre-existing assays

* Increased accuracy in diagnosis compared to current controls

* Consistent and renewable source for high-quality controls containing mutations of interest

Novel In Vitro Granuloma Model for Studying Tuberculosis and Drug Efficacy

   Description of Technology: CDC researchers have developed an in vitro model system designed to simulate early-stage Mycobacterium tuberculosis infection and induced granuloma formation. This modeling platform can be used for studying tuberculosis pathogenicity, identifying phenotypically-interesting clinical isolates, studying early-stage host cytokine/chemokine responses, and in vitro candidate-drug screening. The approach incorporates autologous human macrophages, human peripheral blood mononuclear cells, and mycobacteria to mimic in situ granuloma formation in a controllable in vitro environment. This technology would be broadly useful for investigations into the numerous facets of early granuloma host-pathogen interaction, ultimately leading to improved prevention, intervention, and treatment strategies.

   Potential Commercial Applications:

* In vitro modeling system

* Basic research into tuberculosis-host interactions

* Drug candidate screening

   Competitive Advantages:

* Low-cost alternative for modeling mycobacterial infections within complex tissue systems

* Allows researchers to examine early-stage granuloma formation in a highly controllable, human-based modeling system

Diagnostic Antigens for the Identification of Latent Tuberculosis Infection

   Description of Technology: CDC researchers have developed technology for sero-diagnosis of typically symptomless latent stage tuberculosis disease, posing a threat to individuals under immunosuppressive or anti-inflammatory therapies. Specifically, this diagnostic approach exploits M. tuberculosis secreted latency specific antigens, such as alpha-crystallin, in the blood or urine of patients. This type of test could easily be developed into an inexpensive dip-stick format with high specificity (no cross-reactivity with other mycobacteria), rapidity, and sensitivity (fewer bacteria needed for a positive identification). Because secreted antigens are recognized more readily by the immune system, serum-derived antibodies to these antigens can correspondingly be used for diagnostic or research use.

   Potential Commercial Applications:

* Development of a latent tuberculosis diagnostic

* Improvements to current diagnostics

* Public health/tuberculosis monitoring programs

    * Screening elderly patients before beginning anti-inflammatory and/or anti-arthritis therapy

   Competitive Advantages:

* Rapid and inexpensive diagnostic for latent stage tuberculosis

* Specific for latent form, unlike current IGRA/TST diagnostics

* Easily developed as a cost effective dip-stick test

* Provides high specificity (no cross-reactivity with other mycobacteria) and sensitivity (fewer bacteria needed for a positive identification)

   Development Stage:

* In vitro data available

* In vivo data available (human)

Methods and Apparatus for Computer-Aided Cough Sound Analysis

   Description of Technology: CDC researchers have developed a system that allows subjects to cough into a tubing system allowing the acoustics generated to be recorded with high fidelity and generated data is transferred to a computer for subsequent analysis. Lung diseases can be differentiated by the location of effect in the lungs that produce variations in cough sounds and patterns. Based on these differences, analysis software estimates the lung disease type of the subject. Those who benefit from cough sound analysis include subjects in the early stages of undetected lung disease, subjects with conditions not easily diagnosed by standard techniques, subjects who demonstrate difficulty performing forced expiratory maneuvers and other pulmonary function tests (e.g., elderly, young and very sick patients), and workers whose respiratory functioning may change during the workday.

   Potential Commercial Applications:

* Clinical screening for early-stage respiratory illnesses

* Occupational health and safety

* Physiological data collection and algorithmic analysis

* Preventative and early intervention health care

   Competitive Advantages:

* Increased accuracy in recorded observations

* Improved objectivity in analysis compared to traditional auscultatory methods

* Broadens the diagnostic toolset of primary/initial care physicians and respiratory therapists

* Portable for field studies and on-site screening/diagnostic uses

   Development Stage:

* In situ data available (on-site)

* Prototype

* Studies into pathogenesis regulation, chronic diseases, gene silencing, etc.

* Cancer and obesity research

* Basic research applications

   Competitive Advantages:

* Overcomes a significant barrier inhibiting efficient DNA methylation archival studies

* Substantially reduces the required quantity of sample DNA

* Developed kits will be universally applicable to all species using DNA methylation as regulatory mechanisms of growth, development and/or pathogenesis

* Usable in all situations of limited amounts of DNA, including studies with single cells

* Improved cost effectiveness and study feasibility compared to alternate technologies

Inexpensive, Personal Dust Detector Tube/Dosimeter Operating on a Gas Detector Tube Platform

   Description of Technology: This CDC developed dust detector tube is designed to provide inexpensive, short-term, time weighted average dust exposure data feedback directly to device users. This invention operates upon a conventional gas detector tube platform and can be used with any low volume pump that can electronically measure pump back pressure. The device consists of three sections: the first defines the size of the dust and removes moisture, the second uses a filter whose pressure differential corresponds with cumulative dust loading, and a final section employs a pressure transducer.

   Current methods require expensive instantaneous and short-term monitors or gravimetric filters that must be carefully pre- and post-weighed to determine the average dust exposure of a user's work-shift. This novel dust dosimeter fills the need for an inexpensive short-term determination of personal dust exposure aiding in the assessment and preservation of worker respiratory health.

   Potential Commercial Applications:

* Dust, gas and particulate detector/dosimeter manufacturers

* Industry applications where worker-exposure to dust will be a concern, especially mining, construction and demolition fields

* Worker health and safety, related insurance agency concerns

   Competitive Advantages:

* Provides inexpensive, short-term assessment of personal dust exposure

    * Gas detector tube platform makes commercialization of this instrument quite simple and efficient for related manufacturers/distributors

    * Standardizing detection platforms increases cost-efficiency (especially for smaller companies) as the same pump can be used to measure both dust and gas

   Development Stage: In situ data available (on-site).

Peptide Sequences for Chlamydophila pneumoniae Vaccine and Serological Diagnosis

   Description of Technology: CDC researchers have isolated select Chlamydophila pneumoniae peptide epitopes for development of vaccines and diagnostic assays. Currently, C. pneumoniae infection of humans has been linked to a wide variety of acute and chronic diseases, such as asthma, endocarditis, atherosclerotic vascular disease, chronic obstructive pulmonary disease, sarcoidosis, reactive arthritis and multiple sclerosis. There is presently no available peptide vaccine for the pathogen and reliable and accurate diagnostic methods are limited.

   This technology encompasses polypeptide sequences that are specifically recognized by anti- C. pneumoniae antibodies. These antigens may be useful for improving diagnostic methods by reducing the variability and high backgrounds found with methods that rely on whole organisms for detection. Further, this technology may also be useful for production of peptide or DNA-based vaccines directed against C. pneumoniae.

   Potential Commercial Applications:

* C. pneumoniae vaccine and/or therapeutic developments

* Public health surveillance programs

    * Clinical serological diagnostics development

   Competitive Advantages:

* No peptide vaccine for C. pneumoniae is presently available

* Present assays for the diagnosis of C. pneumoniae infections are laborious and limited in efficacy

   Development Stage: In vitro data available.

CD40 Ligand: Adjuvant for Enhanced Immune Response to Respiratory Syncytial Virus

   Description of Technology: CDC researchers have developed methods and adjuvants for enhancing a subject's immune response to respiratory syncytial virus (RSV) by inclusion of a CD40 binding protein. RSV has long been recognized as a major respiratory tract pathogen of infants, as well as older children and the elderly. Established, successful methods for preventing RSV are currently unavailable. CD40 ligand (CD40L, also known as CD154) is an important costimulatory molecule found on the T-cell and is critical for the development of immunity. CD40L may provide a novel adjuvant to enhance cytokine and antibody response to RSV, directing a subject's immune response further towards Th1-mediated outcomes rather than a less effective Th2-type response. This Th2-type response has been previously suggested as the cause of previous live-RSV vaccine failures. This technology, appropriately developed and integrated into an RSV vaccination agenda, may be useful in improving the efficacy of current or future RSV vaccines.

   Potential Commercial Applications:

* Improvements to current RSV vaccines

* Public health vaccination programs

* Enhancing antibody response and T-cell costimulation for targeted immunogenic outcomes

* Pharma development programs focusing on care for neonates, children and the elderly

   Competitive Advantages:

* Increased expression of Th1-type cytokines and antibody production

* Enhanced CD40 costimulation

* May overcome prior live-RSV vaccine issues (which generated a primarily Th2-type immune response) by steering post-vaccination immunity further towards a preferred Th1-type (IL-2 and IFN-gamma) response, enhancing virus clearance in vivo

   Development Stage:

* In vitro data available

* In vivo data available (animal)

Recombinant Polypeptides for Clinical Detection of Taenia solium and Diagnosis of Cysticercosis

   Description of Technology: CDC scientists have developed synthetic/recombinant polypeptides that can be used for the creation of inexpensive, high-quality cysticercosis diagnostic assays. Taenia solium is a species of pathogenic tapeworm. Intestinal infection with this parasite is referred to as taeniasis and it is acquired by ingestion of T. solium cysticerci found in raw and undercooked pork, or food contaminated with human or porcine excrement. Many infections are asymptomatic, but infection may be characterized by insomnia, anorexia, abdominal pain and weight loss. Cysticercosis is the formation of cysticerci in various body tissues resulting from the migration of the T. solium larvae out of the intestine. Although infection with T. solium is itself not dangerous, cysticercosis can be fatal. In the present invention, specific antigen encoding nucleotide sequences have been cloned; assays based on the produced antigens may be useful for improvements over the existing Western blot diagnostic method for identifying individuals with cysticercosis. Additionally, these polypeptides may have applications in developing vaccines and therapeutics to prevent taeniasis.

   Potential Commercial Applications:

* Diagnosis of T. solium infection and confirmation of cysticercosis

* Zoonotic disease research and surveillance

* Public health monitoring programs

* Livestock health and food-source monitoring

* Therapeutics/vaccine development

   Competitive Advantages:

* May provide a rapid, accurate, sensitive and safe alternative to current radiologic, Western blot and biopsy diagnostic methods

* Can be easily formatted as a simple-to-use assay kit for FAST-ELISA

* Cost-effective, and quite useful for developing regions of the world

Ultrasonic in situ Respirator Seal-Leakage Detection With Real-time Feedback Capabilities

   Description of Technology: This CDC invention entails methods and apparatuses for in situ testing seal integrity and improved operation of respiratory masks (respirators). A variety of external factors, such as individual face shape, user environment, mask age and material used to construct the respirator, can lead to device malfunction and failure to sufficiently protect a user. To address these limitations, this invention relies on ultrasonic wave detection to assess face seal quality and other potential leak paths, as needed. Airborne ultrasound travel through atmosphere and will travel through respirator leaks. Applying this phenomena to occupational health and safety, CDC researchers have developed novel ultrasonics technology to identify and quantify respirator seal leakage in real-time. Small, low power consuming, and inexpensive apparatuses and methods for generating and detecting ultrasound may be easily obtained and customized for a given respirator and/or application.

   By correlating user activity to seal sensor data, a precise understanding and awareness of respirator integrity may be obtained. When coupled with a subject alarm, these integrated values can immediately alert a user when a threshold of environmental exposure has been reached. Such real-time feedback will be invaluable to users in dangerous occupational activities, such as firefighters, biodefense and chemical spill first responders, mining applications, etc. Additionally, this invention possesses immense value for respirator mask manufacturers and workplace training programs for employees engaged in mandatory respirator usage applications.

Physiologic Sampling Pump Capable of Rapidly Adapting to User Breathing Rate

   Description of Technology: This CDC developed physiologic sampling pump (PSP) overcomes shortcomings of previous devices by the use of calibrated valves in conjunction with a constant speed pump. This novel approach obviates typical PSP inertia that inherently limits system response, functionality and accuracy. All prior PSP designs have attempted to follow a user's breathing pattern by changing pump speed, thereby altering sampling rate. In that approach, pump inertia will limit system response and function due to the time required to adjust speed. Additionally, variable pump speeds often produce size selective sampling errors at low flow rates.

   Performance of this PSP is not degraded by pump inertia or low flow size selective sampling errors. This design maintains a consistent pump speed, controlling PSP sampling rate with calibrated valves that redirect air flow almost instantaneously. In situ device testing demonstrated that when this air-flow valve is properly integrated into a sampling head, response time of the PSP is essentially mutually exclusive of the magnitude of changes in the effective flow, facilitating consistently small error in sampling performance regardless of user-exertion scenario.

   Potential Commercial Applications:

* Air sampling device manufacturers

* Assessing airborne hazard exposures for workplace safety

* Industrial hygiene programs

* Respiration monitoring device for patients

* Aerobic training system for athletes

   Competitive Advantages:

* Allows for air sampling to be modulated to follow breathing rate

* Design obviates the sluggishness inherent in prior art physiologic sampling pumps (PSPs) caused by variable pump speed effect on sampling rate

* Improved accuracy compared to earlier PSPs, irrelevant of user-exertion scenarios

* Follows inhalation on a breath-by-breath basis

   Development Stage:

    * In situ data available (on-site)

* Prototype

Cylindrical Handle Dynamometer for Improved Grip-Strength Measurement

   Description of Technology: CDC researchers have developed an improved dynamometer device and method for measuring maximum hand grip force or grip-strength. Human test subjects were used in conducting experiments to evaluate the handle and to assess the measurement method. In contrast to the currently used "Jamar handle" grip strength dynamometer devices, the cylindrical handle proved to be able to determine the overall grip strength for a subject, as well as show the grip force distribution around the circumference of the handle. The cylindrical dynamometer handle is accurate with less than 4% error, and it demonstrates that the measurement is independent of the loading position along the handle. For real-world applications, the device can be used to help diagnose the musculoskeletal disorders of the hand, monitor the recovery progress after hand surgery or injury, and collect grip strength data for tool and machine design.

   Potential Commercial Applications:

* Useful for engineering functional design and ergonomic considerations for developing new tools and machinery

* Monitoring post-operative, post-stroke rehabilitation

* Diagnosis of carpel tunnel syndrome, musculoskeletal disorders and hand-arm vibration syndrome

* Training feedback for grip-strength focused athletes--climbing, gymnastics, rugby, martial arts, etc.

   Competitive Advantages: Compared to currently used "Jamar" grip test devices:

* Cylindrical handle shape more comparable with real-world/workplace machinery

* Improved comfort

* Cylindrical meter assesses the total grip force, together with the friction force and torque

* Grip force distributed at the different parts of the hand can be measured with cylindrical meter--important information for the diagnosis of hand disorders

   Development Stage:

* In situ data available (on-site)

* Prototype

Methods for the Simultaneous Detection of Multiple Analytes

   Description of Technology: CDC researchers have developed a method of simultaneously detecting and distinguishing multiple antigens within a biological sample. Epidemiological and vaccine studies require species serotype identification. Current methods of serotyping are labor intensive and can easily give subjective, errant results. This technology utilizes serotype specific antibodies bound to fluorescent beads, allowing for simultaneous single tube capture and detection of multiple antigens in one rapid, high-throughput flow cytometry assay. Such technology has an extremely wide range of useful applications, including but not limited to complex serotyping investigations for vaccine development and formulation, as a tool for rapid clinical prognosis or diagnosis, and the assay can be formatted as a kit for any number of laboratory research uses.

   Potential Commercial Applications:

* Complex serotyping and/or multi-antigen composition investigations

* Tool for clinical diagnosis or prognosis of a disease or infection

* Tool for basic research

   Competitive Advantages:

* Rapid flow cytometry assay

Extension-Ladder Safety: Multimodal-feedback Indicator for Improved Ladder Positioning Safety and Efficiency

   Description of Technology: Improper positioning of an extension ladder frequently results in "ladder slide-outs," which are the most common cause of ladder-fall scenarios. This invention relates to an extension ladder positioning indicator which is easily installed in a ladder rung; provides multiple cues (visual, sound, and vibration) for rapidly identifying and positioning correct ladder inclination.

   CDC-NIOSH researchers found that this technology improved accuracy and efficiency of ladder positioning for both "experienced" and "novice" ladder users, as compared to the "no instruction" method and the standard anthropometric method, and that it was also significantly faster than the bubble indicator method. When properly implemented, this effective and easy to use ladder positioning indicator will reduce the risk of extension ladder slipping and tipping and, ultimately, will reduce the number of fall incidents and injuries--benefitting construction workers, employers, contractors and workplace insurers.

   Potential Commercial Applications:

* Retrofitting existing ladders to provide automated, multisensory feedback for improved compliance with OSHA and ANSI ladder-angle safety guidelines

* Ladder manufacturing companies

* Construction contractors, retailers and insurers

* Training tool to aid worker safety education and adherence

   Competitive Advantages:

* Direct, multimodal user feedback reduces the time for accurate, safe ladder positioning compared to bubble-level indicator, anthropometric and sight- based ladder-positioning methods

* Visual, auditory and tactile feedback provide increased efficient-setup and safety

* Technology can be incorporated as an attachable, device which may be affixed to a ladder or integrated as an app for a mobile/tablet device

* Automated feedback ensures ladders are angled to OSHA and ANSI safety specifications

   Development Stage:

* In situ data available (on-site)

* Prototype
