  • Patent number: 11814628
    Abstract: The inventive subject matter includes an antimicrobial peptide vectored composition made of a bacterial protein expression vehicle expressing one or more recombinant antimicrobial peptide effector molecules. More specifically these novel recombinant antimicrobial peptide effector molecules exhibit preferential anti-microbial activity. The utility of the current inventive subject matter has demonstrated a reduced viability of Eimeira acervulina sporozoites in vitro using a sporozoite killing assay. More specifically, the antimicrobial peptide vectored composition is a bacterial protein expression vehicle expressing one or more recombinant antimicrobial peptide effector molecules, wherein the one or more recombinant antimicrobial peptide effector molecules are engineered from a NK-lysin gene and the one or more recombinant antimicrobial peptide effector molecules are engineered to express functionally active NK-2.

  • Patent number: 11730161
    Abstract: Provided herein are mechanisms and methods for the automated distribution of active ingredients (whether oral or contact based) to wild and domestic animal populations as well as a method for monitoring animal activity and estimating consumption and/or application of such ingredients within the population through the utilization of the mechanisms themselves. The inventive device pertains to a manner of delivering either an active oral ingredient or active contact ingredient within a bait pellet or like substrate for ingestion or external contact and/or coating of a target population. The device allows for controlled access of such a bait pellet (or like substrate) for such a target population coupled with the ability to retain freshness thereof for multiple timed access events without the need for human involvement. A properly sized, configured, and automated delivery device is thus provided to meet these needs. Delivery components are also encompassed herein.

  • Patent number: 7820115
    Abstract: A laboratory rack assembly for supporting columns and receptacle tubes and other paraphernalia during laboratory procedures such as such as filtration, chromatography, plasma preparation, affinity purification, and so on, includes upper and lower support portions that are connected together for relative sliding movement. An upper rack module is connected to the upper support portion and is configured to receive at least one column. A lower rack module is connected to the lower support portion and is configured to receive at least one receptacle tube. At least one of the rack modules is removably connected to at least one of the support portions. An adjustment mechanism is operably associated with the upper and lower support portions for adjusting a position of one support portion with respect to the other support portion to thereby vary the distance between the upper and lower rack modules.
