چکیده انگلیسی
Toxin-producing cyanobacteria are a worldwide threat to both human and animal health. The hepatotoxins microcystin and nodularin are the most commonly occurring toxins produced by bloom-forming cyanobacteria. They are cyclic peptides that are synthesized nonribosomally by a multienzyme complexes encoded within the microcystin (mcyS) and nodularin (ndaS) synthetase gene clusters. Early detection of potentially toxic blooms would allow for pre-emptive action to reduce consumer exposure to cyanotoxins. We have developed a quantitative PCR (qPCR) assay based on SYBR-green chemistry for the detection of potentially hepatotoxic cyanobacteria spanning all known microcystin and nodularin producing taxa using primers specifically targeting mcyE and ndaF. The qPCR assay was validated against previously analyzed cyanobacterial bloom samples. Whole cell qPCR using cultured M. aeruginosa PCC7806 and non-toxic M. aeruginosa UTEX2386 had a sensitivity of 1000 cells mlâ1. In summary, we have developed a robust and sensitive molecular method for the detection and quantification of hepatotoxigenic cyanobacteria in bloom samples. This technology offers several advantages over traditional and contemporary testing protocols currently used to assess water quality.
