Horizontal and vertical distribution of Gambierdiscus spp. (Dinophyceae) including novel phylotypes in Japan identified by 18S rDNA metabarcoding.

Harmful Algae, 2022
The genus Gambierdiscus is a marine benthic/epiphytic dinoflagellate considered the causative agent of ciguatera poisoning (CP). Clarifying the geographical distribution of this genus to understand the potential risk of CP is important. Many studies have

Identification of Gambierdiscus species from La Réunion and evaluation of toxicity and toxin profile.

Harmful Algae
Five different species of Gambierdiscus have been identified in La Réunion (G. belizeanus, G. balechii, G. pacificus, G. silvae and G. ribotype 2) by morphological observations in Scanning Electron Microscopy (SEM) and molecular identification and ...

Toxicity Screening of a Gambierdiscus australes Strain from the Western Mediterranean Sea and Identification of a Novel Maitotoxin Analogue

Marine Drugs, 2021
Dinoflagellate species of the genera Gambierdiscus and Fukuyoa are known to produce ciguatera poisoning-associated toxic compounds, such as ciguatoxins, or other toxins, such as maitotoxins.

The Evolution of Giant Clam Science: From Foundational Studies to Emerging Frontiers

Aquaculture, Fish and Fisheries, Volume 6, Issue 2, April 2026.
This review synthesizes nearly two centuries of giant clam research, identifying dominant themes, knowledge gaps, and emerging opportunities. Ecology, physiology, aquaculture, genomics, and biomineralization dominate the field, whereas anatomy and biotechnology remain underexplored. Future progress requires stronger integration of genomics, physiology,

Ciguatera Fish Poisoning: The Risk from an Aotearoa/New Zealand Perspective

Toxins, 2020
Gambierdiscus and Fukuyoa species have been identified in Aotearoa/New Zealand’s coastal waters and G. polynesiensis, a known producer of ciguatoxins, has been isolated from Rangitāhua/Kermadec Islands (a New Zealand territory).

Taxonomy, distribution, and habitat associations of Gambierdiscus from coastal waters off Queensland, Australia.

Harmful Algae
Ciguatera poisoning is the most prevalent non-bacterial seafood illness globally, with an estimated 10,000 to 50,000 cases reported annually. It is caused by consumption of seafood (mainly fish) that have accumulated ciguatoxins produced primarily by ...

Ciguatera poisoning: A review of the ecology and detection methods for Gambierdiscus and Fukuyoa species.

Harmful Algae
Ciguatera poisoning is the most prevalent non-bacterial seafood illness globally, with an estimated 10,000 to 50,000 human cases reported annually. While most symptoms are generally mild, some cases can result in severe and long-lasting neurological and ...

Hereditary diffuse gastric cancer: the evolution of a cancer syndrome

Journal of the Royal Society of New Zealand, Volume 55, Issue 6, Page 2636-2651, December 2025.
ABSTRACT Hereditary Diffuse Gastric Cancer (HDGC) is a high risk cancer syndrome caused predominantly by germline mutations in the CDH1 gene. HDGC is characterised by a lifetime risk of advanced diffuse‐type gastric (stomach) cancer of up to 70%, and an additional 40% lifetime risk of lobular breast cancer in women.

Ciguatera-Causing Dinoflagellate Gambierdiscus spp. (Dinophyceae) in a Subtropical Region of North Atlantic Ocean (Canary Islands): Morphological Characterization and Biogeography

Toxins, 2019
Dinoflagellates belonging to the genus Gambierdiscus produce ciguatoxins (CTXs), which are metabolized in fish to more toxic forms and subsequently cause ciguatera fish poisoning (CFP) in humans. Five species of Gambierdiscus have been described from the

Development of Fluorescence in situ Hybridization (FISH) Probes to Detect and Enumerate Gambierdiscus Species

Harmful Algae, 2021
Ciguatera fish poisoning (CFP) is a syndrome caused by the bioaccumulation of lipophilic ciguatoxins in coral reef fish and their subsequent consumption by humans.
