Current research efforts focus on improvement of cell culture systems for the isolation of viruses and on the molecular epidemiology of canine parvovirus. Although new molecular detection methods have rendered the detection of many viruses much faster than previously, the ability to culture viruses remains a necessity, especially for emerging and re-emerging viruses. When a new virus is isolated and amplified in cell culture, the isolate can be used for further characterization as well as for developing new vaccines and new diagnostic assays. Because virus isolation in cell culture is expensive, the goal of my current research is to determine ways of reducing the cost and time of virus isolation by studying the effect of short-term storage of cells at refrigerator temperatures on their susceptibility to virus infections and their usefulness in cell-based diagnostic tests.
Canine parvovirus emerged in the late 1970s and has since become the single most important virus infecting dogs worldwide. There is evidence that the virus has continued to evolve since its emergence and at least three distinct antigenic variants are currently known to occur worldwide. Continuous evolution of the virus means that existing diagnostic tests and vaccines might need to be reformulated periodically to remain effective against current variants of the virus. In the United States, only two of the three known antigenic variants have been described. The goal of my research is to determine the current occurrence and distribution of various antigenic variants of canine parvovirus in the U.S. This information will be useful to vaccine and diagnostic kit manufacturers.
