“Algal-dromes”: a novel conceptual approach to illness in humans exposed to harmful algal bloom toxins [PDF]

Frontiers in Toxicology
Although adverse health effects from harmful algal bloom (HAB) toxins have been described since antiquity, the true worldwide incidence and disease burden has yet to be defined.

Evaluation of the study carried out by ANSES on the effectiveness of sanitary shucking of queen scallops (<i>Aequipecten opercularis</i>) contaminated by okadaic acid toxins. [PDF]

EFSA J
Abstract Following a request from the European Commission, EFSA evaluated the effectiveness of sanitary shucking of queen scallops (Aequipecten opercularis) contaminated with okadaic acid (OA) group toxins. Specifically, EFSA was tasked to evaluate a study conducted by the French Agency for Food, Environmental and Occupational Health & Safety (ANSES ...

Fear of grazing rivals the toxin-inducing effects of nutrients in two marine harmful algae - a meta-analysis. [PDF]

Biol Rev Camb Philos Soc
ABSTRACT One of the major subfields of chemical ecology is the study of toxins and how they mediate interactions between organisms. Toxins produced by harmful algae (phycotoxins) impact a wide variety of organisms connected to the marine food web. Significant research efforts have thus aimed to identify the ecological and evolutionary drivers behind ...

Marine Algal Toxins and Public Health: Insights from Shellfish and Fish, the Main Biological Vectors [PDF]

Marine Drugs
Exposure to toxigenic harmful algal blooms (HABs) can result in widely recognized acute poisoning in humans. The five most commonly recognized HAB-related illnesses are diarrhetic shellfish poisoning (DSP), paralytic shellfish poisoning (PSP), amnesic ...

Molecular Mechanisms of Algicidal Bacteria in Controlling Harmful Algal Blooms: Advances in Bacteria-Algae Interactions. [PDF]

Environ Microbiol Rep
This review elucidates the molecular mechanisms of algicidal bacteria, highlighting critical behaviours like chemotaxis, quorum sensing and extracellular vesicle release. It details how these actions disrupt algal cellular integrity, photosynthesis and calcium homeostasis, providing a theoretical foundation for controlling harmful algal blooms ...

Toxic Effects and Tumor Promotion Activity of Marine Phytoplankton Toxins: A Review

Toxins, 2022
Phytoplankton are photosynthetic microorganisms in aquatic environments that produce many bioactive substances. However, some of them are toxic to aquatic organisms via filter-feeding and are even poisonous to humans through the food chain.
