Several bacteria from the Clostridium genus produce botulinum neurotoxins—the most potent biological toxins known—that cause botulism by blocking neurotransmitter release from nerves. Typically, the ...

Researchers from the University of Maryland School of Medicine and their colleagues have identified the structure of the most lethal toxin produced by certain strains of Clostridium difficile bacteria ...

A new study, led by researchers from the University of California, Irvine (UCI), uncovers the long-sought-after, three-dimensional structure of a toxin primarily responsible for devastating ...

Scientists have determined a three-dimensional (3-D) molecular image of how anthrax toxin enters human cells, giving scientists more potential targets for blocking the toxin, the lethal part of ...

A novel combination of multiple advanced molecular imaging techniques has led to the discovery of two molecular structures, which could provide a therapeutic target for C. diff infections. “The most ...

MELBOURNE, Australia — Over a million children die each year from severe diarrhea, often caused by a dangerous strain of E. coli. Now, researchers at La Trobe University in Australia have mapped the ...

Scientists at La Trobe University have discovered how a diarrhoea-causing strain of bacteria uses “molecular scissors” to cut open and destroy gut cells, leading to severe illness and sometimes death.

The crystal and molecular structure of the Clostridium perfringens α-toxin crowns over a century-long research into the mechanisms of pathogenesis of gas gangrene. The structure reveals a two-domain ...

Chemical pesticides are commonly used as defense against mosquitoes in countries where malaria, dengue fever, and zika virus are present. Pesticides wreak havoc on the environment and can cause ...

Could we get rid of mosquitoes without polluting the environment? Yes, we can, say researchers. The BinAB toxin, produced in crystal form by a bacterium, specifically kills the larvae of Culex and ...
