Distribution P. seriata is a cold-water species. Previously known only from the Northern Hemisphere in the Atlantic, but recently also from the Northern Pacific. Recently, it was reported from the Southern cold Pacific. Due to morphological variability of P. seriata and related species, this needs to be confirmed either by molecular data. [details]
Harmful effect P. seriata has been implicated in toxic episodes in the field in Europe (Denmark, Ireland, Scotland) and Canada. It has caused DA in sea scallops and molluscan shellfish in Canada, in blue mussels in Denmark, and associated with DA in king scallops in Scotland.
DA levels above the regularory limit (20µm g-1) has been found at concentrations of 50-62,000 cells L-1 in Canada and Denmark. [details]
Identification requires electron microscopy.
The main characteristics of P. seriata are the asymmetric valve and the 4 rows of poroids (2 outer rows of larger poroids and 2 inner rows of smaller poroids).
P. seriata is phylogenetically and morphologically closely related to P. obtusa and P. australis, two other species with asymmetric valves. The main differences are the number of poroid rows in the striae, poroid density, and valve width. However, in P. seriata number of poroid rows and poroid density has been found to decrease with increasing temperature, making identification difficult.
P. seriata: (2)-4 rows - 6-9 poroids/µm - 4.6-8.0µm
P. obtusa: 2 rows - 6-8 poroids/µm - 2.9-5.0µm
P. australis: 2 rows - 4-5 poroids/µm - 6.5-8.0µm
Verified sequences of ITS rDNA (ITS1, 5.8S, ITS2) are:
P. seriata (DQ062663); P. obtusa (DQ062667); P. australis (DQ062661)
[details]
Toxicology Strains of the species have been confirmed to produce domoic acid (DA) in cultures from the cold temperate Northern Atlantic and Northern Arctic. Some strains have in addition to DA been shown to produce the two isomers isodomoic acid A (IA) and isodomoic acid B (IB) (Hansen et al. 2011). DA have so far been found to make up the largest proportion of the toxins. DA production in cultures have been found to vary from 0.16 pg cell-1 to 33.6 pg cell-1.
