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.
Symptoms may include diarrhea, vomiting, numbness, itchiness, sensitivity to hot and cold, dizziness, and weakness. [1] [2] The onset of symptoms varies with the amount of toxin eaten. If a large quantity of toxins are consumed symptoms may appear within half an hour. If a low amount of toxins are consumed symptoms may take a few days to appear ...
Copious amounts of red saliva the Komodo dragons produce help to lubricate the food, but swallowing is still a long process (15–20 minutes to swallow a goat). A Komodo dragon may attempt to speed up the process by ramming the carcass against a tree to force it down its throat, sometimes ramming so forcefully that the tree is knocked down. [43]
DSP and its symptoms usually set in within about half an hour of ingesting infected shellfish, and last for about one day. The causative poison is okadaic acid, which inhibits intestinal cellular dephosphorylation. [1] This causes the cells to become very water-permeable and the host to profusely defecate into a high risk of dehydration.
Exposure typically happens when people come into close contact with an infected person, as well as through eating or drinking food or water contaminated with the virus. What the symptoms are ...
Okadaic acid, C 44 H 68 O 13, is a toxin produced by several species of dinoflagellates, and is known to accumulate in both marine sponges and shellfish. [1] One of the primary causes of diarrhetic shellfish poisoning, okadaic acid is a potent inhibitor of specific protein phosphatases and is known to have a variety of negative effects on cells.
Toxic encephalopathy is a neurologic disorder caused by exposure to neurotoxic organic solvents such as toluene, following exposure to heavy metals such as manganese, as a side effect of melarsoprol treatment for African trypanosomiasis, adverse effects to prescription drugs, or exposure to extreme concentrations of any natural toxin such as cyanotoxins found in shellfish or freshwater ...
The Komodo Biosphere Reserve and National Park is situated between Flores and Sumbawa in Indonesia. It is renowned for its population of about 5,000 giant lizards, called 'Komodo dragons' (Varanus komodoensis). They exist nowhere else in the world and are of significant interest to scientists studying the theory of evolution. [1]
