Rabies Vaccine for the Oral Immunization of Domesticated Animals, Wildlife and Feral Animals

Description of Technology: This invention, developed by the CDC and collaborators, entails a live, attenuated recombinant rabies virus vaccine that can elicit an effective anti-rabies immune response in animal recipients. Inoculation with a live, attenuated, rabies virus allows for the optimized production of immunity in the absence of pathogenicity. Oral administration of rabies vaccines is often a preferred route of vaccine delivery because it is most effective in wildlife. Unfortunately, availability of an oral vaccine for canines has been a significant hurdle to date.

This vaccine technology could be used for immunization of stray dogs by an oral route. In developing nations, more than 90% of human exposure events and 99% of human deaths due to rabies are caused by rabid dogs. Using this vaccine with a broadly implemented oral vaccination strategy provides a promising opportunity for reducing transmission of rabies between stray dogs and, thereby, increasing protection for people.

Potential Commercial Applications:

  • Wildlife and humane shelter rabies prevention and control programs
  • Improved rabies vaccines for pets and livestock
  • Humane, targeted approach to elimination of rabies reservoirs in feral animal populations

Competitive Advantages:

  • Safe and effective
  • Oral immunization is the most practical and efficient method of rabies vaccination of wildlife and feral animals
  • Vaccine has demonstrated protection in vivo
  • Recombinant, non-neuroinvasive virus expressing a neuroinvasive glycoprotein and/or pro-apoptotis gene safely induces a robust and desirable immunological response

Development Stage:

  • In vitro data available
  • In vivo data available (animal)

Lead Detection Wipes for Potentially Contaminated Surfaces

Description of Technology: This CDC-developed invention relates to a method for the detection of lead on surfaces (such as, for example, skin, floors, walls, windows sills) using a `handwipe' system and a chemical test effecting a characteristic color change if contaminating lead is present. This invention is especially useful in detecting the presence of lead on skin and assessing the effectiveness of hand washing in removal of lead from the skin of exposed individuals. Further, this invention is useful in field evaluation for the presence of lead, exposure of individuals to lead, and the effectiveness of its subsequent removal in the workplace, home, school, and similar environments.

Potential Commercial Applications:

  • Suitable for lead-testing surfaces such as floors, walls, windowsills and human skin
  • Evaluation of lead-removal effectiveness from surfaces in homes, hospitals, workplaces and schools
  • Confirming hand/skin/shoe/clothing-washing effectiveness of lead removal for military, target range personnel

Competitive Advantages:

  • Simple color-change readout indicates the presence of lead on a surface
  • Rapid test; lead concentration can be inferred by degree of color shift
  • Safe for use on skin

Development Stage:

  • In vitro data available
  • In situ data available (on-site)

Mining Safety: Personal Dust Monitor Filters for Accurate, Quantifiable Spectrometric Analysis and Assessment of Worker Exposure Levels

Description of Technology: This CDC-developed invention pertains to a novel dust monitor filter that is specially constructed of organic materials for spectrometric analysis, ultimately allowing for detection and accurate quantification of a particular chosen analyte (e.g., crystalline silica/quartz dust that may lead to silicosis).

For miners, the risk of lung disease increases with the extent of dust exposure, and coal worker's pneumoconiosis (aka, black lung disease) and silicosis are still dangers routinely faced by those in the industry. Expectedly, both the concentration and the composition of airborne particulate matter present in mining environments are points of regulatory concern. For some time, collecting airborne dust samples and subsequent determination of quartz content have been integral for assessing mine worker exposure and demonstrating compliance with US Federal regulations.

Unfortunately, highly accurate spectrometric detection and quantification of particulate exposure has not always been possible. Generally, the filters used in existing oscillating microbalances (such as the TEOM® monitor) have been specially designed to for hydrophobicity, in order to retain as little moisture as possible on the filter. These specialized hydrophobic filters (and/or their mounting components) contain inorganic compounds that cannot be readily subjected to thermal or chemical destruction—a necessary first step of many instrumental analytical methods, such as spectroscopy.

This CDC-developed filter consists of entirely ashable material, making it ideal for spectrometric analysis and rapid exposure assessment. As an example, this dust monitor filter can be made entirely of organic materials and designed for quick, easy ashing that will not produce interference with the spectroscopic characteristics of the chosen analyte(s). Further, filter ashing can be carried out by a variety of methods: thermal ashing, microwave ashing, low temperature ashing, or chemical destruction.

Potential Commercial Applications:

  • Personal dust monitors worn wherever dust exposure levels and the presence of potentially injurious materials is evaluated
  • Occupationally-mandated pneumoconiosis, asbestosis and/or silicosis prevention and monitoring programs, for complying with safety regulations
  • Miners' wellness concern groups and insurance companies

Competitive Advantages:

  • Novel dust-monitoring instrument capable of providing near rapid particulate exposure information to miners/users
  • Improves upon older technology by allowing for accurate detection and quantification of chosen analyte(s) and, unlike other filters, does not produce overlap or interfere with spectroscopic analysis
  • Filter can be easily ashed for analysis by thermal ashing, microwave ashing, low temperature ashing, or chemical destruction

Development Stage:

  • Early-stage
  • In vitro data available

Computer Controlled Aerosol Generator With Multi-Walled Carbon Nanotube Inhalation Testing Capabilities

Description of Technology: This invention pertains to a CDC-NIOSH developed sonic aerosol generator that provides a controllable, stable concentration of particulate aerosol over a long period of time for aerosol exposure studies. Specifically, in situ testing data indicate uniform aerosol stability can be maintainable for greater than 30 hours at concentrations of 15 mg/m3 or more. Additionally, the technology was specifically developed for, and validated in, animal studies assessing exposure to airborne multi-walled carbon nanotubes (MWCNT). It has been suggested that workers may be at risk for exposure to nanosized particles during the manufacture, handling, and cleanup of engineered nanomaterials. Compared to other technologies, this NIOSH aerosol generator is particularly helpful when used for generating high testing concentrations of MWCNT aerosols that more accurately represent particulate levels that may be seen in a workplace environment.

Potential Commercial Applications:

  • Studying the size and shape of the aerosolized particles produced from simple vibrations of bulk material
  • Toxicological investigations and risk assessment of aerosol exposures, especially those related to nanoparticle manufacturing.
  • Any aerosolization application where the aggregating “bird's nest” tendencies of airborne multi-walled carbon nanotubes must be overcome

Competitive Advantages:

  • Fully automated system with integrated feedback control for optimized stability in testing
  • Maintains concentration of aerosols for >30 hours at concentrations of 15 mg/cubic meter or more
  • Capable of generating high concentrations of aerosols that more accurately represent the levels seen in a workplace environment
  • System insures that each run produces a constant particle concentration, air flow, pressure, temperature and humidity within a testing chamber

Development Stage:

  • In vitro data available
  • In vivo data available (animal)
  • In situ data available (on-site)
  • Prototype
