1 Tests showed increased levels of toxin in shellfish. 2 They were close to weaponizing ricin—a lethal plant toxin. 3 The water had been tainted with a deadly toxin. 4 Cholera toxin did not cause nausea or vomiting. 5 The secretory response to cholera toxin developed gradually. 6 Mycotoxin: any toxin produced by a fungus. 7 The plant toxin renders both the caterpillar and the adult butterfly particularly repellent to natural enemies. 8 Obtainable under the proprietary name Chlordane,[www.] the toxin gradually works down into the soil diffusing into the soil atmosphere. 9 The secretory effect of cholera toxin in our study probably continued for hours as evidenced by the stool output after the experiment. 10 This delayed effect of cholera toxin is well known from animal experiments. 11 There are several candidates for the toxin that might cause toxic shock syndrome. 12 In experimental animals cholera toxin induces marked secretion of fluid and electrolytes. 13 When cholera toxin is used as secretagogue a variable response in stool volume should thus be expected. 14 Cholera toxin caused no change in potential difference in any of the groups. 15 Adding the copper, which is another metal toxin, only hastened the death of the fish. 16 Botulism toxin from bacteria prevents the release of acetylcholine and is the most poisonous substance known. 17 The toxin produced by the fungus grows in moldy feed. 18 Cholera toxin reduced absorption of water and electrolytes progressively over four hours and induced secretion in a dose dependent fashion. 19 In our experiments the secretory effect of cholera toxin began in the second hour after administration of the toxin. 20 However, it can grow in cream at room temperatures and produces a toxin as it multiplies. 21 The tetanus bacteria grow at the site of the injury and release a toxin which produces rigid muscles and muscle contractions. 22 The first changes of net water and ion transport were observed after the second or third hour after administration of cholera toxin. 23 The next day the rods were identified as Corynebacterium diphtheriae var gravis, and were shown to produce toxin. 24 Every 13 weeks Beck receives 300 units of the botulinum toxin, which reaches peak effect in about five weeks. 25 Nevertheless, the most reliable evidence strongly suggests that the children of the war are suffering from secondhand exposure to the toxin. 26 It appeared the water supply had been tainted with a deadly toxin. 27 There, they were exposed to bacteria that had been manipulated to carry genes for the E. coli toxin. 28 Even though cooking may destroy the bacterial cells, it is unlikely to inactivate the toxin. 29 Worldwide, indeed, surplus nutrient is at least as dangerously polluting as pure toxin. 30 Because infection with Vibrio cholerae is an important cause of diarrhoea, we decided to use cholera toxin as intestinal secretagogue.
