A rough-skinned newt underwater A rough-skinned newt at Brice Creek in Oregon. Throughout much of the newt's range, the common garter snake (Thamnophis sirtalis) has been observed to exhibit resistance to the tetrodotoxin produced in the newt's skin. While in principle the toxin binds to a tube-shaped protein that acts as a sodium channel in ...
Pyrrolizidine alkaloidosis poisoning in the United States has remained moderately rare among humans. The most common reports are the outcome of the misuse of medicinal home remedies, or the alkaloids are present in food and drink substances such as milk and honey when the animal carriers were exposed to the toxins.
There are several causes of toxic optic neuropathy. [1] Among these are: ingestion of methanol (wood alcohol), ethylene glycol (automotive antifreeze), disulfiram (used to treat chronic alcoholism), halogenated hydroquinolones (amebicidal medications), ethambutol and isoniazid (tuberculosis treatment), and antibiotics such as linezolid and chloramphenicol as well as chloroquine and the related ...
Several recent intoxications from these fishes in Florida were due to saxitoxin, which causes paralytic shellfish poisoning with very similar symptoms and signs. The trumpet shell Charonia sauliae has been implicated in food poisonings, and evidence suggests it contains a tetrodotoxin derivative.
Neurotoxic shellfish poisoning (NSP) is caused by the consumption of brevetoxins, which are marine toxins produced by the dinoflagellate Karenia brevis (among several others). These toxins can produce a series of gastrointestinal and neurological effects.
The Coastal Range newt produce a potent poison called tetrodotoxin from specialized glands in their skin. Ingestion of this poison by handling or eating them causes severe neurological symptoms and, in some instances, death from respiratory or cardiac failure. The toxin found in juveniles is several times more potent than that in adults.
Amnesic shellfish poisoning (ASP) is an illness caused by consumption of shellfish that contain the marine biotoxin called domoic acid. [1] In mammals , including humans, domoic acid acts as a neurotoxin , causing permanent short-term memory loss , brain damage , and death in severe cases.
There are three types of lathyrism: neurolathyrism, osteolathyrism, and angiolathyrism, all of which are incurable, differing in their symptoms and in the body tissues affected. [ 1 ] Neurolathyrism is the type associated with the consumption of legumes in the genus Lathyrus that contain the toxin oxalyldiaminopropionic acid (ODAP).
