Unformatted text preview: toring approaches. The detection and quantitation of speciﬁc target genes, such as those involved in the
synthesis of toxins in cyanobacteria, are the cornerstone of new
techniques to identify, monitor, or proﬁle speciﬁc targets in
environmental samples. These approaches are in general less
expensive and faster than the currently available chemical assays and do not rely on reference standards.
The structure of the microcystin biosynthesis cluster of two Toxic cyanobacterial blooms, as well as their increasing
global occurrence, pose a serious threat to human health, domestic animals, and livestock. The frequency and severity of
bloom events continue to rise, most probably as a direct result
of increased nutrient loading of water systems worldwide. The
number of lakes in Quebec, Canada, affected by blooms of 2
104 cells ml 1 or more has been increasing from 21 (2004) to
28 (2005), 62 (2006), 157 (2007), 138 (2008), and 150 (2009).
Government agencies are under tremendous pressure to cope
with escalating demands for water analysis, speciﬁc...
