Microsatellite development for a tetrodotoxin-containing sea slug (Pleurobranchaea maculata)

Biochemical Systematics and Ecology, 2014
Abstract Using 454 pyrosequencing data, 24 polymorphic microsatellite markers were identified for the grey side-gilled sea slug, Pleurobranchaea maculata . The grey side-gilled sea slug is found throughout the western and south Pacific and is known to contain high concentrations of tetrodotoxin.

The invasive sea slug Pleurobranchaea maculata is a vector of two potent neurotoxins in coasts of Argentina

Marine Biology, 2019
Toxic exotic organisms can have profound effect as new vectors of keystone compounds in non-native areas. In recent years the invasive sea slug Pleurobranchaea maculata has been reported as thriving along the oriental coasts of South America. The same species had been previously found to contain high levels of tetrodotoxins (TTXs) in its native range ...

Development of a non-lethal biopsy technique for estimating total tetrodotoxin concentrations in the grey side-gilled sea slug Pleurobranchaea maculata

Toxicon, 2013
High concentrations of tetrodotoxin (TTX) have been detected in some New Zealand populations of Pleurobranchaea maculata (grey side-gilled sea slug). Within toxic populations there is significant variability in TTX concentrations among individuals, with up to 60-fold differences measured.

Diet of the invasive sea slug Pleurobranchaea maculata in Patagonian coastal waters

New Zealand Journal of Zoology, 2018
ABSTRACT High densities of the invasive sea slug, Pleurobranchaea maculata , have been detected on the Argentinean coast, but studies on the species’ adaptation have been absent until now. Stomach contents of P.

Genetic barcoding confirms the presence of the neurotoxic sea slug Pleurobranchaea maculata in southwestern Atlantic coast [PDF]

New Zealand Journal of Zoology, 2016
ABSTRACT This work extends a previous report on the outbreak of an unknown neurotoxic sea slug along the southwestern Atlantic coast by providing identification to species level. In this study a c. 550 base pair (bp) region of the cytochrome c oxidase subunit 1 mitochondrial gene used for genetic barcoding was ...

In situ accumulation of tetrodotoxin in non-toxic Pleurobranchaea maculata (Opisthobranchia)

Aquatic Sciences, 2016
Tetrodotoxin (TTX) is a highly potent neurotoxin targeting voltage gated sodium channels. It is found in numerous phyla, including both marine and terrestrial taxa, however, its origin is a topic of considerable debate. The aim of this study was to investigate the origin of TTX in the Opisthobranch Pleurobranchaea maculata using in situ experimentation.

First identification of tetrodotoxin (TTX) in the flatworm Stylochoplana sp.; a source of TTX for the sea slug Pleurobranchaea maculata

Toxicon, 2015
High concentrations of the neurotoxin tetrodotoxin (TTX) were detected by liquid chromatography-mass spectrometry (LC-MS) in the Platyhelminthes Stylochoplana sp. from Pilot Bay (Tauranga, New Zealand). This is the first detection of TTX in this genus. Concentrations were monitored from March to November (2013) and found to significantly decrease from ...
