E. coli Exposed! W. Conard Holton Abstract
image credit: Dennis Kunkel Microscopy, Inc., Matt Ray/EHP The potentially fatal microbial pathogen Escherichia coli O157:H7 has been identified as the source of several major food- and waterborne disease outbreaks in the United States resulting in some of the most severe foodborne illness in children. Researchers are working to develop testing technologies that can more quickly detect and quantify numbers of E. coli O157:H7, which can cause illness with just a few bacteria. One breakthrough employs liposomes to detect E. coli O157:H7 and other pathogens. Another, which uses magnetic beads coated with monoclonal antibodies, could help public health officials cut valuable days off the time it takes to test swimming pools and other bodies of water for contamination.
