Introduction
Toxins are substances that are synthesized by living organisms,
which are harmful to humans. These can be produced
by some bacteria, fungi, vertebrates, or marine microorganisms
[11], which usually live in symbiosis with reefs in tropical and subtropical waters. Some micro-algae synthesize
a large group of toxins, known as ‘‘paralytic shellfish poisoning’’, which have a chemical structure consisting of
a common quinazolinic derivative with different associated
ions. The toxin is especially accumulated in the fish skin and
gonads and in the mollusk intestine and liver, and its level
increases by bioaccumulation throughout the food chain
from micro-algae to humans. While toxins do not affect
fishes [6], humans can be affected. Tetrodotoxin (TTX) is
considered the most lethal toxin originating in thntaminated
trumpet shellfish captured in the southern coast oe marine
environment. Its name comes of the Tetraodontidae family,
but it was later found in other fishes and mollusks [15].
