Microbial degradation and impact of Bracken toxin ptaquiloside on microbial communities in soil

Chemosphere, 2007
The carcinogenic and toxic ptaquiloside (PTA) is a major secondary metabolite in Bracken fern (Pteridium aquilinum (L.) Kuhn) and was hypothesized to influence microbial communities in soil below Bracken stands. Soil and Bracken tissue were sampled at field sites in Denmark (DK) and New Zealand (NZ).

Role of Toxins in Plant Microbial Interactions

1998
Both plants and fungi produce a wide variety of low molecular weight natural products. Many of these compounds were once considered secondary metabolites with no particular biological role in the producing organism. Understanding the chemical interactions between plants and microorganisms can be complex and requires an integrated approach.

Microbes and Microbial Toxins: Paradigms for Microbial- Mucosal Interactions II. The integrated response of the intestine toClostridium difficiletoxins

American Journal of Physiology-Gastrointestinal and Liver Physiology, 2001
Clostridium difficile, the major etiologic factor of antibiotic-associated diarrhea and colitis, mediates its effects by releasing two large protein exotoxins, toxins A and B. A major toxin effect is related to the disassembly of actin microfilaments, leading to impairment of tight junctions in human colonocytes.

Microbial toxins, their functional role and phylogenetic validity

Biosystems, 1978
Microbially produced toxins, which appear to lack a role in microbial survival, may be antimicrobial compounds of significance to the producers. These toxin/antibiotics may act against cell metabolism shared by man or animals and other microorganisms. Protein toxin/antibiotics are produced by single species of bacteria.

Microbial Toxin Production: Opportunists and True Pathogens

Journal of Drug Metabolism & Toxicology, 2014
A toxin is a poisonous substance produced within living cells or organisms. Toxins can be small molecules, peptides, or proteins that are capable of causing disease on contact with or absorption by body tissues interacting with biological macromolecules such as enzymes or cellular receptors.

Photorhabdus: A Microbial Factory of Insect-Killing Toxins

2015
The overuse of chemical pesticides to meet the production and productivity goals in modern agriculture is causing a number of unintended side effects and destruction of the environment. Eco-friendly pest management techniques and strategies are urgently needed. Photorhabdus spp.
