The Kidney Vero-E6 Cell Line: a Suitable Model to Study the Toxicity of Microcy...

Microcystins (MCs) are toxins produced by cyanobacteria from water environments that can induce acute and chronic effects on humans and animals, after ingestion/contact with contaminated water. This group of cyclic heptapeptides comprises approximately 80 variants, being microcystin-LR (MCLR) the most frequent and toxic variant. The studies of MCs effects on cell lines often lead to contradictory results, given...

Evaluation of phylogenetic markers suitable for Planktothrix spp. discrimination

In Portugal, potentially toxic cyanobacteria from Planktothrix genus have become frequently observed in freshwater reservoirs. Identification of Planktothrix species through optical microscopy is complicated due to limited morphological differences among them. The aim of this work was to determine the most suitable phylogenetic markers that could be used for the molecular identification of Planktothrix species....

Cyanobacterial blooms in natural waters in southern Portugal: a water managemen...

This synthesis of 3 studies from 2 regions of southern Portugal (Alentejo and Algarve) was part of a workshop focusing on cyanobacteria held at the SAME 10. The first study monitored impacts of the large Alqueva dam on the Guadiana estuary since 1996, revealing changes in sediment load, nutrient regime and phytoplankton succession. Prior to dam construction, dense cyanobacterial blooms occurred in the upper est...

Toxic cyanobacteria blooms in Portuguese freshwaters – a summarized overview

Toxic cyanobacteria are common in Portuguese freshwaters and are a cause of concern, given that exposure to subacute levels of cyanobacterial toxins through drinking and recreational water might have deleterious effects on human health. Since 1996 several laboratories have been involved in the screening of cyanotoxins in different freshwater bodies, some on regularly basis and others more sporadically. Here we ...
