This site is no longer maintained and has been left for archival purposes Bacillus thuringiensis. B. thuringiensis (commonly known as 'Bt') is an insecticidal bacterium, marketed worldwide for control of many important plant pests-mainly caterpillars of the Lepidoptera (butterflies and moths) but also mosquito larvae, and simuliid blackflies that vector river blindness in Africa.. thuringiensis strains produce two types of toxin. The main types are the Cry (crystal) toxins, encoded by different cry genes, and this is how different types of Bt are classified. The second types are the Cyt (cytolytic) toxins, which can augment the Cry toxins, enhancing the effectiveness of insect control.

--Chapt. Pathogenic bacteria (bacteria capable of causing disease) because they release chemicals called toxins. Toxins are classified as either endotoxins or exotoxins.Endotoxins produce toxic substances which are stored in their cell walls and released when the bacterial cells are lysed (broken open).athogenic bacteria (bacteria capable of causing disease) because they release chemicals called toxins. Toxins are classified as either endotoxins or exotoxins.

- 1 Examples include arsenic, benzene, and radiation. 2  A toxin is a highly toxic protein produced by certain plants, animals or pathogenic bacteria. 3  Examples include snake venom and anthrax. 4  All toxins are toxicants, but only those toxicants produced by living organisms are toxins.

- Bt toxin is produced by Bacillus thuringiensis in an inactive form (protoxin), which is transformed to its active form (delta-endotoxin) in the guts of certain insects. The active toxin binds to receptors in the gut, killing the insect.

- For example, some invade the lining of the intestines, causing inflammation, while others produce toxins. E. coli that produce poisons called Shiga toxins are generally the only type of E. coli that are tested for in clinical settings from stool specimens.

- There are two general kinds of bacterial toxins. \5\ Exotoxins are produced during the growth phase of certain kinds of bacteria and are liberated into the medium or tissue. Exotoxins are protein in nature and their reactions are specific.

Toxins Toxins. CDC has developed specific and sensitive methods to help diagnose, treat, and prevent diseases caused by toxins. Toxins from bacteria, fungi, algae, and plants are some of the most deadly chemicals known and represent an ongoing public health threat. Saxitoxin and neosaxitoxin are produced by several species of marine and fresh water algae and blue-green algae (cyanobacteria). 2  When these organisms are present in high concentrations, the toxins may build up in filter-feeding shellfish, such as clams and oysters.

Microbial toxin Microbial toxins promote infection and disease by directly damaging host tissues and by disabling the immune system.Some bacterial toxins, such as Botulinum neurotoxins, are the most potent natural toxins known. However, microbial toxins also have important uses in medical science and research.otential applications of toxin research include combating microbial virulence, the development of novel anticancer drugs and other medicines, and the use of toxins as tools in neurobiology and cellular biology.
