Repetitive extragenic palindromic PCR fingerprinting of Escherichia coli is one microbial source tracking approach for identifying the host source origin of fecal pollution in aquatic systems. The construction of robust known-source libraries is expensive and requires an informed sampling strategy. In many types of farming systems, waste is stored for several months before being released into the environment.
Dr. Asit Mazumder (biology) has been awarded a three-year $7 3, grant from the Canadian Institutes of Health Research (CIHR) to study how molecular and biochemical tools can be used to track bacterial and chemical contamination in drinking water. The study, which is being supplemented with $18 , from Health Canada and $5 , from Agriculture Canada and the beef and cattle industry, will examine the validity of various techniques used for tracking E.
