AI Technical Summary

Benefits of technology

This patented technology helps prevent damage from losing important viruses like feline caliciviridae (FCAV) or porcinerus rotavis due to freezing drying processes performed on different types of veterinary medications such as horse sickness treatments. By mixing certain ingredients with this new method, it provides an effective way to make sure these drugs are safe while still maintain their ability to stimulate immune responses against specific diseases.

Problems solved by technology

This patents discuss different types of animal reservoir fluids like blood, urine, sputum, swabs, sporides, bitigens, and others. These liquids contain harmful microorganisms responsible for veterinary concern worldwide including avid herds, rodworms, horseshoe warts, tickles, dementias, and prurence syndrome. Current methods involve administering therapeutoxvirus based therapies against both epidemics and nonfatal cases associated with exposure to specific strains found around human populations during timespan distribution.
