Latest Toxins Stories
Biochemists at North Carolina State University have answered a fundamental question of how important bacterial proteins make life-and-death decisions that allow them to function
By Mark Cowan AIR ambulance medics made a mercy dash to London and back to get an antidote for a patient bitten by a snake. The woman, from Stafford, was taken to hospital after being bitten by an adder while out walking near the Millford Common area of Cannock Chase on Monday.
ROSS Finnie, Liberal Democrat health spokesman, has referred to clostridium difficile on a number of occasions as a viral infection. Could I just clarify that clostridium species are bacteria, which can produce very nasty toxins. Hence the terrible results at the Vale of Leven Hospital.
Most snakes are born with poisonous bites they use for defense. But what can non-poisonous snakes do to ward off predators? What if they could borrow a dose of poison by eating toxic toads, then recycling the toxins?
A toxin that can make bacterial infections turn deadly is also found in higher plants researchers have found.
More lizard families than previously believed are venomous, including several species that are popular pets, scientists said on Wednesday.
New research shows that bacteria lurking in household dust produce chemicals that may trigger asthma and asthma-related symptoms such as wheezing. These bacterial chemicals, called endotoxins, particularly those found on bedroom floors, were linked with increased respiratory problems in adults.
By Amy Norton NEW YORK (Reuters Health) - Exposure to bacterial toxins may cause flu-like symptoms, breathing problems and skin reactions in some workers at sewage treatment plants, a study has found.
Scientists at Harvard Medical School (HMS) have revealed details of a key step in the entry of anthrax toxin into human cells. The work, which grew out of an ongoing effort to produce a better anthrax therapeutic, shows that the protective antigen component of the bacterial toxin plays an active role in transferring the other two components of the toxin through the cell membrane.
Scientists claim that frogs and toads are becoming extinct all over the world. Some say it's the same magnitude event as the extinction of the dinosaurs. Scientists fear they could be indicator species -- a sign of possible future damage to other parts of the ecosystem because frogs and toads are especially vulnerable and thus are the first to disappear.
The Western Diamondback Rattlesnake, Crotalus atrox, is a species of venomous rattlesnake found in the United States and Mexico. It is found in California, Arizona, New Mexico, Oklahoma and Texas. It prefers flatlands and prairies to the rocky hills and low mountains. This snake is generally colored dark or light brown. Its pattern is a unique row of large, dark diamond shapes edged in yellow trim, running down the length of its body. The diamonds fade to dark rings around the tail, where...
Rattlesnakes are a group of venomous New World snakes (genera Crotalus and Sistrurus) which have a small jointed rattle on their tails. They use this rattle as a warning device when they feel threatened. The rattle is composed of a series of nested, hollow beads which are actually modified scales from the tail-tip. Each time the snake sheds its skin, a new rattle segment is added. Since they may shed their skins many times a year (depending on food supply and consequent growth rates), and...
