Freshwater clams capture and accumulate the virus that causes bird flu, according to Fort Collins researchers.
The Colorado State University and U.S. Department of Agriculture researchers say they plan to travel to Vietnam this summer to see whether the clams can be used to help track the disease.
Birds in Southeast Asia catch and carry the flu virus and shed some of it in their feces. The virus often ends up in streams, according to CSU researchers.
Scientists have been able to use mechanical filters to search for viruses in the water. The filters, however, are expensive.
Natural filters, such as filter-feeding clams, may work better, according to preliminary work by Kate Huyvaert, a CSU biologist, and Alan Franklin, with the USDA's National Wildlife Research Center.
This summer, the researchers will work in northern Vietnam, where they will expose Asiatic clams to bodies of water used by birds infected with bird flu. Katy Human: 303-954-1910 or khuman@denverpost.com
