HABs Karenia brevis and Pseudo-nitzschia pre- and post-Hurricane Michael. [PDF]

J Water Health, 2023
Increased occurrences of harmful algal blooms (HAB) in the Gulf of Mexico, and even worldwide, yield concern for increases in brevetoxin exposure leading to respiratory illness or even death, highlighting the need for extensive scientific research and ...

Profiling of Brevetoxin Metabolites Produced by Karenia brevis 165 Based on Liquid Chromatography-Mass Spectrometry. [PDF]

Toxins (Basel), 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 ...

Karenia brevis Extract Induces Cellular Entry through Distinct Mechanisms in Phagocytic RAW 264.7 Macrophages versus Non-Phagocytic Vero Cells. [PDF]

Mar Drugs, 2023
Marine algae extracts are an important area of potential drug discovery; however, nearly all studies to date have used non-fluorescent-based methods to determine changes in target cell activity. Many of the most robust immunological and cellular analyses

Diverse ssRNA viruses associated with <i>Karenia brevis</i> harmful algal blooms in southwest Florida. [PDF]

mSphere
Harmful 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.

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,

Cell death responses to acute high light mediated by non-photochemical quenching in the dinoflagellate Karenia brevis. [PDF]

Sci Rep, 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 ...

Comparative Quantitative Proteomic Analysis of High and Low Toxin-Producing Karenia brevis Strains Reveals Differences in Polyketide Synthase Abundance and Redox Status of the Proteome. [PDF]

Mar Drugs
To identify differentially abundant polyketide synthases (PKSs) and to characterize the biochemical consequences of brevetoxin biosynthesis, bottom-up, TMT-based quantitative proteomics and redox proteomics were conducted to compare two strains of the ...
