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, a finding that could provide a new target for drugs to disrupt bacterial decision-making processes and related diseases.In a study published this month in the journal Structure, the NC State scientists show for the first time that the specific movements of these important bacterial proteins, called transition-state...

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. Despite a national shortage of antidote for the snake's venom, the medical team tracked down the medicine at the toxicology unit at Guy's Hospital, in London. The County Air Ambulance set off from their...

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. The cause of this outbreak is no doubt multi-factorial but we must all be more vigilant when it comes to correct handwashing, etc. Dr Robert McGonigle, Dumbarton Health Centre. Originally published by...

Research may hold promise for medical treatment of high blood pressure 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? That's exactly what happens in the relationship between an Asian snake and a species of toad, according to a team of researchers funded by the National Science Foundation (NSF) Division of Integrative...

A toxin that can make bacterial infections turn deadly is also found in higher plants, researchers at UC Davis, the Marine Biology Laboratory at Woods Hole, Mass. and the University of Nebraska have found. Lipid A, the core of endotoxin, is located in the chloroplasts, structures that carry out photosynthesis within plant cells. The lipid A in plant cells is evidently not toxic. The human intestine contains billions of Gram-negative bacteria, but lipid A does not become a problem unless...

By Wendel Broere LEIDEN, Netherlands -- More lizard families than previously believed are venomous, including several species that are popular pets, scientists said on Wednesday. Until now, pain and swelling from lizard bites assumed to be non-venomous were attributed to the bacteria that thrive on bits of meat left between their teeth from their scavenging diet. However, the symptoms are actually from the venom, a finding which could have implications for medical research, said Dr. Bryan Fry...

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. This study, supported by the National Institute of Environmental Health Sciences (NIEHS), a part of the National Institutes of Health, is the first nationwide study of endotoxins in the household...

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. Researchers in the Netherlands found that workers at 67 sewage treatment plants had heightened risks of daily cough, shortness of breath, skin rash and flu-like symptoms such as headache and body aches and pains. The culprit, say the researchers, seems to be the toxins that are...

BOSTON - 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. The research, led by R. John Collier, professor of microbiology and molecular genetics at HMS, provides...

QUITO, Ecuador -- Before the arrival of Spanish colonizers some 500 years ago, Indians in what is now Ecuador dipped their arrowheads in venom extracted from the phantasmal poison frog to doom their victims to convulsive death, scientists believe. More recently, epibatidine -- the chemical which paralyzed and killed the Indians' enemies -- has been isolated to produce a pain killer 200 times more powerful than morphine, but without that drug's addictive and toxic side effects....

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...
