Research on FIP has steadily progressed over the last decade. Join veterinary professionals and breeders at the presentation of Dr. Niels Pedersen from the University of California-Davis, a world-renowned researcher on infectious diseases in cats, during the 2011 Winn Feline Foundation Symposium in Reston, VA. Dr. Pedersen describes how some of our concepts of disease pathogenesis, potential treatment modalities, mutations within the virus that affect the virulence, genetic susceptibility of the host cat, and disease prevention have either changed or have become much clearer. The role of breeders and their veterinarians in solving the problem of FIP remains even more important today than at any time in the past.
