Waterborne pathogens and microbial GMOs in aquatic ecosystems

This Study investigates the sources and occurrence of waterborne   pathogens and microbial GMOs/biotechnology products in aquatic   ecosystems.  It also investigates the potential of these organisms to   pose threats to water quality.  The Study goals are to: 1) understand   the importance of different sources of fecal pollution in aquatic   ecosystems; and 2) develop methods to detect waterborne pathogens,   microbial GMOs and other biotechnology products in aquatic ecosystems   and to better understand their occurrence and potential threats to   water quality.  i)  Investigate and apply methods to track sources of fecal pollution   in aquatic ecosystems.  -  continue GL2 2  project initiated in 2  1- 2 to apply a rep-PCR   technique for DNA fingerprinting of E. coli isolates to better   understand the basis for beach closures in the Hamilton/Burlington   area.  It is proposed to expand this project in 2  2- 3 (in   collaboration with AEMRB Charleton/ Marvin), to apply the rep-PCR   microbiological technique and a coprostanol chemical technique to   identify sources of fecal pollution in Hamilton Harbour and to   determine if waterborne E. coli isolates are from human, bird, or   other animal sources.       -  initiate a new GL2 2  project to investigate and compare a variety   of newly emerging techniques for tracking sources of fecal   pollution.  Proposal would use NWRI's recently acquired Agilent   Bioanalyzer   ii)  Develop methods to detect waterborne pathogens and study their   occurrence in aquatic ecosystems.  -  establish Level 2 lab to support research on waterborne pathogens.  -  continue EMBRR project to develop PCR assays for wildlife   pathogens (iii)  Investigate potential threats to water quality posed   by waterborne pathogens, microbial GMOs and other biotechnology   products.  -  continue EMBRR DNA microarray project (Brousseau, NRC-BRI;   Trevors, Univ. of Guelph) and transfer technology on DNA extractions   and DNA microarray scanning/arraying to NWRI (subject to availability   of DNA microarray equipment at NWRI).  -  initiate research collaborations with waterborne disease team   (Univ. of Guelph; Health Canada; EC-ESD-HQ) on new project to   investigate potential climate change influences on incidence of   waterborne disease outbreaks in Canada.
