Abstract:
The disclosure provides a cell freezing and storage bag assembly and a method for using the assembly in banking eukaryotic cells for later seed train expansion. The bag is constructed principally of fluorinated ethylene propylene (FEP) fabric, and is designed to be filled such that the cell suspension has a very thin cross-section. The bag design includes at least an inlet conduit and an outlet or inoculation conduit, which can be sterilely welded to the source of the eukaryotic cells. The use of at least two sterile-weldable conduits allows for “closed system” filling of the bags, which significantly reduces the risk of contamination relative to other cell-banking methods. The bag also include a sleeve, which can be thermo-welded to form an enclosure, which protects the inlet and outlet conduits against contamination and mechanical damage during freezing, storage and subsequent thawing. In the method, once each bag is filled, its corresponding inlet conduit is sealed, and both the inlet and outlet conduits are enclosed within the bag's sleeve. This closed system method obviates the need for sterile environments (e.g. laminar flow unit).
Abstract:
The disclosure relates to an extended-range spray applicator, and methods of making and use thereof, for dosing vaccines and/or probiotics to avian animals at a distance.
Abstract:
The present invention provides a method of maintaining a gram negative bacterium plasmid without the use of antibiotic selection pressure. Further, the invention relates to the drugless plasmids produced including drugless plasmids containing a heterologous gene. The invention also provides formulations and/or compositions comprising the drugless plasmids comprising a heterologous gene, formulations and/or compositions comprising a protein or an immunogen expressed using the drugless plasmids, and methods of administering such formulations and/or compositions to a host. The invention relates to gram negative bacteria containing the drugless plasmids.
Abstract:
The present invention relates to novel stable compressed vaccine composition comprising at least one anhydrous antigenic component comprising a stabilizer susceptible to foaming when the composition is mixed with liquid diluent; and an effective amount of a sugar alcohol.
Abstract:
This invention relates to long-acting injectable formulations for combating parasites in animals, comprising at least one isoxazoline active agent, a poloxamer, and a co-solvent. This invention also provides for improved methods for eradicating, controlling, and preventing parasite infections and infestations in an animal comprising administering the long-acting injectable formulations of the invention to the animal in need thereof.
Abstract:
The present invention relates to novel dihydroazole of formula (I) and salts thereof: Wherein R1, A1, A2, G, X and Y are as defined in the description, compositions thereof, processes for their preparation and their uses to prevent or treat parasitic infections or infestations in animals and as pesticides.
Abstract:
The invention relates to oral, topical or injectable compositions for combating liver fluke parasites in mammals, comprising at least one indole derivative active agent. The invention also provides for an improved method for eradicating and controlling liver fluke parasite infections and infestations in a mammal comprising administering the compositions of the invention to the mammal in need thereof.
Abstract:
The present invention provides in ovo injection devices, including a novel vaccine/substance conservation valve (VCV), a needle depth adjuster (NDA), and methods for selectively delivering vaccines and other substances to eggs in the context of poultry hatcheries. The valve of the present invention allows for the conditional dispensing of vaccines and other substances dependent upon the presence or absence of an egg. When an egg is present, the valve becomes activated, allowing vaccines or other substances to be injected. When an egg is absent, the valve is not activated, thus vaccines and other valuable substances are conserved. The NDA allows embryonated eggs to be more safely injected by reducing the depth of needle penetration, particularly in smaller eggs.
