Effect of phytoplankton containing paralytic shellfish and amnesic shellfish toxins on the culture of the king scallop Pecten maximus in Málaga (SE Spain)

open access: yes, 2006
The impact of toxic outbreaks of Gymnodinium catenatum, producer of paralytic shellfish poisoning toxins (PSP toxins) and Pseudonitzschia spp., producer of amnesic shellfish poisoning toxins (ASP toxins), was studied throughout the culture cycle of the ...

Evolutionary trade‐offs between beauvericin production and growth define divergent virulence strategies in Beauveria

open access: yesPest Management Science, EarlyView.
Two virulence strategies in Beauveria: a growth strategy characterized by rapid within‐host proliferation, and a toxin strategy involving antimicrobial activity and toxicity to insects Abstract BACKGROUND Pathogen virulence is often attributed to toxin production, yet toxins are metabolically costly and may not universally enhance fitness.

Integrating bioassays and transcriptomics to detect neonicotinoid resistance in Australian Bemisia tabaci MEAM1

open access: yesPest Management Science, EarlyView.
The Bemisia tabaci MEAM1 strain GR15‐1R shows partial resistance to neonicotinoids (bottom), which correlates with an increased expression of the P450 gene CYP6CM1 compared to the insecticide‐susceptible strain SU07‐1 (top). Abstract BACKGROUND Bemisia tabaci MEAM1 is a highly invasive and polyphagous pest species of agricultural and horticultural ...

Botulinum toxin in the treatment of paralytic strabismus and essential blepharospasm.

open access: yesIndian journal of ophthalmology, 1993
As an alternative to conventional medical and surgical modalities that have met little success in the treatment of paralytic strabismus and essential blepharospasm, we explored the use of botulinum toxin as a treatment of choice in these two disorders.

Searching for Paralytic Toxin, Tetrodotoxin, in Swedish Bivalve Shellfish

open access: yesMarine Drugs
Tetrodotoxin (TTX), earlier known as a tropical paralytic neurotoxin from pufferfish poisoning, has increasingly been occurring in edible marine species, including filter-feeding bivalves, from relatively cold marine waters of some European countries.

Winter accumulation of paralytic shellfish toxins in digestive glands of mussels from Arcachon and Toulon (France) without detectable toxic plankton species revealed by interference in the mouse bioassay for lipophilic toxins

open access: yes, 1999
Since January 1993, neurological symptoms and rapid deaths (5 to 10 min) were typically observed in the mouse bioassay of acetone extracts of digestive glands from Arcachon and Toulon (France) during the winter season. It was assumed initially that a new
