Comparative Genomics of Bacillus thuringiensis Reveals a Path to Specialized Exploitation of Multiple Invertebrate Hosts

open access: yesmBio, 2017
Understanding the genetic basis of host shifts is a key genomic question for pathogen and parasite biology. The Bacillus cereus group, which encompasses Bacillus thuringiensis and Bacillus anthracis, contains pathogens that can infect insects, nematodes,

Molecular architecture and activation of the insecticidal protein Vip3Aa from Bacillus thuringiensis

open access: yesNature Communications, 2020
Bacillus thuringiensis Vip3 (Vegetative Insecticidal Protein 3) toxins are widely used in biotech crops to control Lepidopteran pests. Here authors present the cryo-EM structures of the protoxin and the protease-activated state of Vip3Aa which shed light

An Insect Toxin from Spores of Bacillus thuringiensis and Bacillus cereus [PDF]

open access: yesJournal of General Microbiology, 1975
Spores of Bacillus thuringiensis contain a toxin active against lepidopterous larvae. This toxin can be solubilized by extraction with reagents which dissolve the protein crystal of B thuringiensis. It is inactivated by crystal-specific antiserum. Spores of Bacillus cereus contain a similar toxin although the specific activity is much lower than the ...

Understanding the structure and function of Bacillus thuringiensis toxins [PDF]

open access: yesToxicon, 2016
As biological control agents take an expanding share of the pesticides market and the production of insect-resistant crops increases, it is essential to understand the structure and function of the active agents, the invertebrate-active toxins that are the fundamental ingredients of these control systems.

The Prevalence and Control of Bacillus and Related Spore-Forming Bacteria in the Dairy Industry [PDF]

open access: yes, 2015
peer-reviewedMilk produced in udder cells is sterile but due to its high nutrient content, it can be a good growth substrate for contaminating bacteria. The quality of milk is monitored via somatic cell counts and total bacterial counts, with prescribed ...
