A pangenomic study of Bacillus thuringiensis

Journal of Genetics and Genomics, 2011
Bacillus thuringiensis (B. thuringiensis) is a soil-dwelling Gram-positive bacterium and its plasmid-encoded toxins (Cry) are commonly used as biological alternatives to pesticides. In a pangenomic study, we sequenced seven B. thuringiensis isolates in both high coverage and base-quality using the next-generation sequencing platform.

Antitrichomonal strains of Bacillus thuringiensis

Parasitology Research, 2002
Parasporal inclusion proteins from a total of 816 Bacillus thuringiensis strains isolated in Japan were examined for antitrichomonal activity against Trichomonas vaginalis. Ten strains of B. thuringiensis inhibited the growth of T. vaginalis in 48 h cultures at 37 degrees C.

A Replication Origin of Bacillus thuringiensis

Current Microbiology, 2000
A replication origin of Bacillus thuringiensis (Bt) was found in a Bacillus thuringiensis-Escherichia coli shuttle vector of pHT3101. Deletion analysis showed that the replication origin was segregationally stable at suitable temperature for Bt growth. The fragment containing the replication origin was cloned in pUC18 and sequenced.

Siderophores of Bacillus anthracis, Bacillus cereus, and Bacillus thuringiensis

Biochemical and Biophysical Research Communications, 2006
Three Bacillus anthracis Sterne strains (USAMRIID, 7702, and 34F2) and Bacillus cereus ATCC 14579 excrete two catecholate siderophores, petrobactin (which contains 3,4-dihydroxybenzoyl moieties) and bacillibactin (which contains 2,3-dihydroxybenzoyl moieties). However, the insecticidal organism Bacillus thuringiensis ATCC 33679 makes only bacillibactin.

A micromethod for serotyping Bacillus thuringiensis

Letters in Applied Microbiology, 1996
Serotyping of Bacillus thuringiensis is possible using 96-well microplates instead of tubes. The advantages are a reduction on the incubation time from 120 to 75 min and the amounts of antisera and bacterial suspensions needed 10-fold.

Bacillus thuringiensis: an impotent pathogen?

Trends in Microbiology, 2010
Bacillus thuringiensis (Bt) is an insecticidal bacterium that has successfully been used as a biopesticide for many years. It is usually referred to as a soil-dwelling organism, as a result of the prevalence of its spores in this environment, but one that can act as an opportunistic pathogen under appropriate conditions.

Polysomes from Bacillus subtilis and Bacillus thuringiensis

Nature, 1969
ONE of the limiting factors in attempts to set up cell-free systems for the manufacture of endogenous proteins is the preservation of intact polysomes. The strand of messenger RNA connecting the bacterial ribosomes is very fragile and is easily broken by mechanical cell disruption1–4. In consequence the commonly used procedures for disrupting bacterial

Evolution of Resistance to Bacillus Thuringiensis

Annual Review of Entomology, 1994
Insecticides derived from the common soil bacterium Bacillus thuringiensis (Bt) are becoming increasingly important for pest management. Insecticidal crystal proteins (also called 8-endotoxins) from Bt are extremely toxic to certain pests, yet cause little or no hann to humans, most beneficial insects, and other nontarget organisms (19, 40).

What is Bacillus Thuringiensis

Arboriculture & Urban Forestry, 1981
Bacillus thurlngiensis (Bt) is a bacterium that belongs to the genus Bacillus. It is pathogenic to insect larvae, mainly Lepidoptera species. Several insecticidal toxins can be produced by the different strains of Bt. The most important one is the crystal (delta-endotoxin) which, alone or in conjunction with the spore, will kill the insects.
