Diverse ssRNA viruses associated with Karenia brevis harmful algal blooms in southwest Florida [PDF]
mSphereHarmful algal blooms (HABs) caused by the dinoflagellate Karenia brevis frequently occur in the eastern Gulf of Mexico, where they negatively impact the environment, human health, and economy. Very little is known about viruses associated with K.

Electroporation and lysis of marine microalga Karenia brevis for RNA extraction and amplification [PDF]
Journal of the Royal Society Interface, 2011 We describe here a simple device for dielectrophoretic concentration of marine microalga Karenia brevis non-motile cells, followed by electric field-mediated lysis for RNA extraction. The lysate was purified using magnetic beads and pure RNA extracted. RNA quality was assessed off-chip by nucleic acid sequence-based

Profiling of Brevetoxin Metabolites Produced by Karenia brevis 165 Based on Liquid Chromatography-Mass Spectrometry [PDF]
Toxins, 2021 In this study, Karenia brevis 165 (K. brevis 165), a Chinese strain, was used to research brevetoxin (BTX) metabolites. The sample pretreatment method for the enrichment of BTX metabolites in an algal culture medium was improved here.

Quantifying Karenia brevis bloom severity and respiratory irritation impact along the shoreline of Southwest Florida. [PDF]
PLoS ONE, 2022 Nearly all annual blooms of the toxic dinoflagellate Karenia brevis (K. brevis) pose a serious threat to coastal Southwest Florida. These blooms discolor water, kill fish and marine mammals, contaminate shellfish, cause mild to severe respiratory ...

Cell death responses to acute high light mediated by non-photochemical quenching in the dinoflagellate Karenia brevis [PDF]
Scientific Reports, 2022 Programmed cell death (PCD) can be induced in microalgae by many abiotic challenges via generation of reactive oxygen species (ROS). Marine phytoplankton live in a highly variable light environment, yet the potential for excess photosynthetically ...

Explosive exhalations by common bottlenose dolphins during Karenia brevis red tides [PDF]
Heliyon, 2020 Harmful algal blooms (HABs) such as those produced by Karenia brevis have acute negative impacts on common bottlenose dolphins (Tursiops truncatus) in Florida coastal waters, frequently causing illness and death. However, much less is known about chronic,
