Tetrodotoxin (TTX) is a potent neurotoxin.Its name derives from Tetraodontiformes, an order that includes pufferfish, porcupinefish, ocean sunfish, and triggerfish; several of these species carry the toxin.
The standard treatment is to support the respiratory and circulatory systems until the poison is metabolized and excreted by the victim's body. [9] Researchers have determined that a fugu's tetrodotoxin comes from eating other animals infested with tetrodotoxin-laden bacteria, to which the fish develops insensitivity over time. [10]
Vibrio alginolyticus is a Gram-negative marine bacterium. [1] [2] It is medically important since it causes otitis and wound infection. [1]It is also present in the bodies of animals such as pufferfish, where it is responsible for the production of the potent neurotoxin, tetrodotoxin.
Hallmark symptoms of ciguatera in humans include gastrointestinal, cardiovascular, and neurological effects. [5] [6] Gastrointestinal symptoms include nausea, vomiting, and diarrhea, usually followed by neurological symptoms such as headaches, muscle aches, paresthesia, numbness of extremities, mouth and lips, reversal of hot and cold sensation, [7] [8] ataxia, vertigo, and hallucinations.
The puffer fish is known for carrying lethal amounts of tetrodotoxin. Tetrodotoxin (TTX) is a poison produced by organisms belonging to the Tetraodontiformes order, which includes the puffer fish, ocean sunfish, and porcupine fish. [55] Within the puffer fish, TTX is found in the liver, gonads, intestines, and skin.
Pufferfish that are born and grown in captivity do not produce tetrodotoxin until they receive some of the poison-producing bacteria, often by eating tissues from a toxin-producing fish. Also, some fish are more poisonous than others. Each fish has enough poison to kill around thirty adult humans. [citation needed]
Researchers from the Nagoya University Graduate School of Medicine in Japan have found eating small fish whole may reduce all-cause and cancer mortality risk in Japanese women.
Species of puffer fish (the family Tetraodontidae) are the most poisonous in the world, and the second most poisonous vertebrate after the golden dart frog.The active substance, tetrodotoxin, found in the internal organs and sometimes also the skin, paralyzes the diaphragm muscles of human victims, who can die from suffocation.
