First Report of Domoic Acid Production from Pseudo-nitzschia multistriata in Paracas Bay (Peru)
TLDR
Routine monitoring of this genus should be considered in order to ensure public health, and its detection in P. multistriata indicates that it is a potential risk.
Phylogenetic relationships of Pseudo-nitzschia subpacifica (Bacillariophyceae) from the Mexican Pacific, and its production of domoic acid in culture
TLDR
It is confirmed that P. subpacifica can produce domoic acid (DA), a neurotoxin responsible for the Amnesic Shellfish Poisoning, under P-limited conditions that could be associated with extraordinary oceanographic events such as the 2013–2016 "Blob" in the northeastern Pacific Ocean.

Toxicity of the Diatom Genus Pseudo-nitzschia (Bacillariophyceae): Insights from Toxicity Tests and Genetic Screening in the Northern Adriatic Sea
TLDR
All subclades of the Pseudo-nitzschia genus contain toxic species and that toxicity appears to be strain dependent, often with geographic partitioning.
Direct evidence for toxin production by Pseudo-nitzschia plurisecta (Bacillariophyceae) and extension of its distribution area
TLDR
An amnesic shellfish poisoning risk associated with domoic acid production by the species Pseudo-nitzschia plurisecta is confirmed and the toxin profile is determined, which includes three domeic acid isomers.
High proliferation of Pseudo-nitzschia cf. arenysensis in the Adriatic Sea: ecological and morphological characterisation
TLDR
Characterise the diatom Pseudo-nitzschia community during a bloom period together with environmental conditions and Spearman rank correlation showed that salinity was an important environmental factor affecting the vertical distribution of Pseudo.
Complete mitochondrial genome of the harmful algal bloom species Pseudo-nitzschia delicatissima (Bacillariophyceae, Bacillariophyta)
TLDR
The complete mitochondrial genome of Pseudo-nitzschia delicatissima was determined for the first time andylogenetic analysis revealed that P. delicatISSima was clustered well with P. multiseries.
Update of the Planktonic Diatom Genus Pseudo-nitzschia in Aotearoa New Zealand Coastal Waters: Genetic Diversity and Toxin Production
TLDR
This study is the first geographical distribution record of P. arenysensis, P. galaxiae, and P. hasleana in New Zealand coastal waters.

Pseudo-nitzschia (Bacillariophyceae) species, domoic acid and amnesic shellfish poisoning: revisiting previous paradigms
TLDR
Gaps in knowledge include further information about the whole genome of Pseudo-nitzschia, mechanisms of DA production and decline, presence or absence of a resting stage, heterotrophic ability, impact of viruses and fungi, and a more complete description of the ecological and physiological roles of DA.
Toxic Pseudo-nitzschia multistriata (Bacillariophyceae) from the Gulf of Naples: morphology, toxin analysis and phylogenetic relationships with other Pseudo-nitzschia species
TLDR
P. multistriata was the only one found to produce domoic acid among all the Pseudo-nitzschia species from the Gulf of Naples, and this finding raises the number of potentially toxic species in this genus to nine.
Blooms of Pseudo-nitzschia pseudodelicatissima and P. calliantha, and associated domoic acid accumulation in shellfish from the South Brazilian coast
TLDR
P. pseudodelicatissima was recorded in high abundance at 5 of the 50 shellfish farms along the Santa Catarina coastline in 2009, and was associated with high concentrations of DA in mussel tissues.
Taxonomical diversity of Pseudo‐nitzschia from the Central Adriatic Sea
TLDR
The results represent the first taxonomical investigation of the genus Pseudo‐nitzschia in Kaštela Bay, as well as the first report of DA in shellfish from this area.
MORPHOLOGY OF THE MARINE DIATOM NITZSCHIA NAVIS‐VARINGICA, SP. NOV. (BACILLARIOPHYCEAE), ANOTHER PRODUCER OF THE NEUROTOXIN DOMOIC ACID
TLDR
A new marine diatom is found to produce the neurotoxin domoic acid (DA), better known from several species of Pseudo‐nitzschia Peragallo and one species of Amphora Ehrenberg, which is therefore more widespread among diatoms than previously thought.
Description of Pseudo-nitzschia cuspidata var. manzanillensis var. nov. (Bacillariophyceae): morphology and molecular characterization of a variety from the central Mexican pacific
TLDR
A new pseudo-cryptic taxon is described within the Pseudo-nitzschia/pseudodelicatissima/cuspidata complex, as a variety of P. cuspidata.
