Toxin-antitoxin systems: Classification, biological roles, and applications.

Microbiology Research, 2022
Toxin-antitoxin (TA) systems, composed of a stable toxin and a cognate unstable antitoxin, are ubiquitous in the genomes of bacteria and archaea.

Biological methods for marine toxin detection

Analytical and Bioanalytical Chemistry, 2010
The presence of marine toxins in seafood poses a health risk to human consumers which has prompted the regulation of the maximum content of marine toxins in seafood in the legislations of many countries. Most marine toxin groups are detected by animal bioassays worldwide.

Medical aspects of biologic toxins

Anesthesiology Clinics of North America, 2004
Biologic toxins are molecules produced by living organisms that are poisonous to other species, such as humans. Some biologic toxins are so potent and relatively easy to produce that they have been classified as biothreat agents. These include the botulinum neurotoxins, ricin, staphylococcal enterotoxin B, and Clostridium perfringens epsilon toxin ...

Biologic response to environmental toxins

The American Journal of Forensic Medicine and Pathology, 1983
Biological response to environmental toxins results from the sum of natural, environmental, avocational, inapparent, and occupational exposures. These external exposures result in acceptable or unacceptable levels of absorption or internal exposure based on anticipated biological effects.

Anti-idiotype-based vaccines against biological toxins

Toxicology and Applied Pharmacology, 1991
Biological toxins produced by living organisms represent one of the major sources of contamination of stored grain and agricultural products, and other food sources. The majority of these biological toxins are highly lethal, nonproteinaceous low-molecular-weight chemical compounds which exert their potent toxicity through a variety of mechanisms ...

Yeast killer toxins: from ecological significance to application.

Critical Reviews in Biotechnology, 2019
Killer toxins are proteins that are often glycosylated and bind to specific receptors on the surface of their target microorganism, which is then killed through a target-specific mode of action.

BIOLOGICAL ASSAY OF THE TOXIN FROM SHELLFISH

Canadian Journal of Biochemistry and Physiology, 1955
A conventional quantal response assay procedure was employed to determine the LD50 of shellfish extracts. The slope of the log dose – response line obtained with butter clam extracts was not significantly different from that found with scallop liver extracts.
