American scientists develop vaccine for liver abscesses in cattle
T.G. Nagaraja, a professor of diagnostic medicine and pathobiology, and M.M Chengappa, professor of microbiology and department head of diagnostic medicine and pathobiology, developed the vaccine that was recently given approval by the United States Department of Agriculture. According to Nagaraja, abscesses are a common malady found mostly in grain-fed cattle, the result of an aggressive feeding programme. He said about 20 to 40% of the grain-fed cattle in feedlots are afflicted with abscesses, which cannot be detected until the animals are slaughtered. While the organ is condemned and not used for sale, in most instances the remainder of the carcass is approved for sale.
