Current Biology, 2009 The compounds that we recognize as toxins and venoms span an enormous diversity of pharmacological and ecological functions. The selection pressures driving the modification of venoms and toxins are fundamentally different from those of other proteins, and result in somewhat different evolutionary dynamics.

JAMA: The Journal of the American Medical Association, 1901 Our object in presenting this paper is merely to outline the theory of the nature and action of the bacterial toxins which we are endeavoring to demonstrate, and to describe our method of work and the results which we have reached through the experiments we have so far made, which are very incomplete and really only a beginning toward the thorough ...

Bioscience Reports, 1977 Summary1. Death in several infectious diseases is caused by protein toxins secreted by invading bacteria. Cholera toxin is a simple protein secreted by Vibrio cholerae colonizing the gut; it is responsible for the massive diarrhoea that is cholera.2. The primary action of cholera toxin is an activation of adenylate cyclase, an enzyme found on the inner

The Toxins of Cyanobacteria [PDF]
Acta Medica (Hradec Kralove, Czech Republic), 2001 Cyanobacteria, formerly called ”blue-green algae“, are simple, primitive photosynthetic microorganism wide occurrence in fresh, brackish and salt waters. Forty different genera ofCyanobacteriaare known and many of them are producers of potent toxins responsible for a wide array of human illnesses, aquatic mammal and bird morbidity and mortality, and ...

CsrA and its regulators control the time-point of ColicinE2 release in Escherichia coli [PDF]
Scientific Reports 8, 6537 (2018), 2018 The bacterial SOS response is a cellular reaction to DNA damage, that, among other actions, triggers the expression of colicin - toxic bacteriocins in Escherichia coli that are released to kill close relatives competing for resources. However, it is largely unknown, how the complex network regulating toxin expression controls the time-point of toxin ...

Alternative to Animal Use for Detecting Biologically Active Staphylococcal Enterotoxin Type A
Toxins, 2018 Staphylococcal enterotoxins (SEs) are a food safety concern. Existing methods for biologically active SE detection rely on the emetic response in live kittens or monkeys.

Environmental toxicity influences disease spread in consumer population [PDF]
arXiv, 2022 The study of infectious disease has been of interest to ecologists since long. The initiation of epidemic and the long term disease dynamics are largely influenced by the nature of the underlying consumer (host)-resource dynamics. Ecological traits of such systems may be often modulated by toxins released in the environment due to ongoing anthropogenic
