  • Apparatus and Methods for Treating and Preventing Disease in Livestock
    Publication number: 20260191632
    Abstract: The invention is a medicament apparatus (1) for use with animals comprising a body (10) made from one or more solid metals, the metals selected from among those for which their ions have biocidal effect. The body comprises an internal porous matrix (11) of at least 1% porosity from which biocidal metal ions can be released, and an external surface of the body (10) is configured to be situated at a treatment site (20) of an animal (2).

  • Air sampler for pathogens and psychrometrics
    Patent number: 6514721
    Abstract: An air sampler device and method for collecting airborne pathogens and psychrometric data for room or remote air samples wherein the sample volume is electronically controlled. Particulates in the air are caused to impact the surface of the growth/inhibitor media contained in the pathogen dish thereby depositing pathogenic microorganisms in the media. The growth/inhibitor media may be a solid, liquid, gel, or mixture thereof. After the pathogen dish is incubated, colony forming units are counted for determination of air quality parameters. A chip-based sensor measures psychrometric properties of the air sample.
