SUMMARY:Using customized DNA microarrays for microbial pathogen detection a
 nd source tracking in assessing water quality.
DESCRIPTION:Conférence du Dr Luke Masson\, Institut de recherche en biote
 chnologie. Cette conférence sera prononcée en anglaisRésuméIn assessin
 g water quality\, fecal pollution monitoring is of great significance for 
 public health as the major source of waterborne pathogens is derived essen
 tially from the large number of pathogenic microorganisms associated with 
 contaminating fecal material. Considering that over 60% of emerging infect
 ious disease events are caused by the transmission of an infectious agent 
 from animals (zoonoses)\, with 75% of these originating from wildlife\, fe
 cal source tracking assumes even greateer importance.Due to the plethora o
 f fecal-associated pathogens\, the microbiological quality of water is pri
 marily monitored using fecal indicator organisms\, such as total coliforms
 \, fecal coliforms\, Escherichia coli\, enterococci and Clostridium perfri
 ngens yet this approach provides little information as to the pathogenicit
 y of the specific organism as well as the contamination source.Comprehensi
 ve analyses of complex DNA samples with regards to microbial biodiversity\
 , single isolate genotyping\, microbial virulence assessment and source tr
 acking requires a multitude of gene queries. Exploitation of the parallel 
 processing power of custom designed DNA microarrays provides a powerful wa
 y to address this problem through the probing of numerous gene targets sim
 ultaneously. This presentation will discuss the design and deployment of c
 ustom DNA microarrays to detect and evaluate the potential virulence of wa
 ter pathogens and the source identification of animal fecal contamination 
 in Canadian watersheds.Conférence présentée par le Département de micr
