Article Synopsis
  • The study focused on creating new oligonucleotide primers to detect microcystin-producing genotypes in Brazilian cyanobacteria from environmental water samples.
  • Microcystins were detected using HPLC in all tested strains and the majority of environmental samples, with the new primers successfully identifying microcystin-producing genes even in samples where HPLC didn’t detect microcystins.
  • These primers showed better specificity and reliability than existing methods, highlighting the importance of tailored molecular markers for regional biodiversity, potentially reducing costs and time in monitoring microcystins.

The accumulation of saxitoxins (STXs) in fish from freshwater aquaculture was investigated for the first time in the present study. Cyanotoxins have been monitored in liver and muscle samples of Oreochromis niloticus by chromatographic methods, both before and after the depuration process. The results show that tilapia can accumulate STXs.
