Molecular Mechanisms of Algicidal Bacteria in Controlling Harmful Algal Blooms: Advances in Bacteria‐Algae Interactions

Environmental Microbiology Reports, Volume 18, Issue 2, April 2026.
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 ...

Ingestion of Alexandrium pacificum Cysts by a Deposit Feeder: An Option for Ecosystem‐Based Approach Benefiting Aquaculture and Coastal Communities?

New Zealand Journal of Marine and Freshwater Research, Volume 60, Issue 1, March 2026.
Harmful algal blooms caused by the paralytic shellfish toxin‐producing species Alexandrium pacificum have increased in recent years in one of the most important aquaculture regions of New Zealand, the Marlborough Sounds. Reoccurring blooms have created large cysts beds in the sediments throughout the sounds. In this region, large populations of the sea

Microbial Ecology at the Nexus of Food Safety and Biotechnology With Ecological Mechanisms, Risks, and Emerging Innovations

International Journal of Food Science, Volume 2026, Issue 1, 2026.
Food systems are complex microbial ecosystems in which microorganisms play dual and often contrasting roles as agents of foodborne contamination and as essential drivers of food production and biotechnological innovation. Microbial ecology provides an integrative framework for understanding how microbial interactions, environmental conditions, and ...

Grazer‐induced bioluminescence and toxicity in marine dinoflagellates

Limnology and Oceanography, Volume 70, Issue 12, Page 3769-3783, December 2025.
Abstract Marine copepods are the most abundant multicellular zooplankton in the global oceans. They imprint their surrounding waters with a unique bouquet of chemical compounds, including polar lipids such as copepodamides. Prey organisms can detect copepodamides and respond by inducing defensive traits including bioluminescence, toxin production ...

Neurotoxins from Marine Dinoflagellates: A Brief Review

Marine Drugs, 2008
Dinoflagellates are not only important marine primary producers and grazers, but also the major causative agents of harmful algal blooms. It has been reported that many dinoflagellate species can produce various natural toxins.

An Overview on the Marine Neurotoxin, Saxitoxin: Genetics, Molecular Targets, Methods of Detection and Ecological Functions

Marine Drugs, 2013
Marine neurotoxins are natural products produced by phytoplankton and select species of invertebrates and fish. These compounds interact with voltage-gated sodium, potassium and calcium channels and modulate the flux of these ions into various cell types.

Comparative paralytic shellfish toxin accumulation in three important Aotearoa New Zealand marine invertebrate species: kina (Evechinus chloroticus), pāua (Haliotis iris) and hohehohe (Panopea zelandica)

New Zealand Journal of Marine and Freshwater Research, Volume 59, Issue 5, Page 1252-1264, December 2025.
ABSTRACT This study investigated the potential for paralytic shellfish toxin (PST) accumulation in three of Aotearoa New Zealand's (NZ) taonga seafood species: kina (urchin; Evechinus chloroticus), pāua (abalone; Haliotis iris) and hohehohe (geoduck; Panopea zelandica) in laboratory exposures to the dinoflagellate Alexandrium pacificum.

Nutrient‐driven regulation of saxitoxin gene expression and toxin production in Raphidiopsis raciborskii (Cyanobacteria)

Journal of Phycology, Volume 61, Issue 6, Page 1738-1752, December 2025.
Abstract Raphidiopsis raciborskii is a diazotrophic cyanobacterium, globally distributed in aquatic environments and known for forming toxic blooms, thereby affecting ecosystem services. South American strains are producers of saxitoxins, potent neurotoxins harmful to humans and animals.

PARALYTIC SHELLFISH POISON-I

NIPPON SUISAN GAKKAISHI, 1962
1. A series of paralytic shellfish poisoning occurred from eating “akazara-gai”, a kind of scallop (Chlamys sp.) in Ofunato City, Iwate Prefecture from May 18 to 20, 1961, in which 20 persons including one death developed symptoms. The epidemiological data indicated that the outbreak was quite similar, to that reported in foreign countries. 2.
