Transport of Bacillus thuringiensis var. kurstaki via fomites.
The intentional and controlled release of an aerosolized bacterium provides an opportunity to investigate the implications of a biological attack. Since 2006, Los Alamos National Laboratory has worked with several urban areas, including Fairfax County, VA, to design experiments to evaluate biodefense concepts of operations using routine spraying of Bacillus thuringiensis var. kurstaki (Btk). Bt...
متن کاملSafety of Bacillus thuringiensis var. kurstaki Applications for Insect Control to Humans and Large Mammals
This minireview discusses the risks to humans and large mammals associated with the use of Bacillus thuringiensis var. kurstaki (Btk) in forest, agricultural and urban environments. The first subspecies used for insect control was Bacillus thuringiensis subsp. thuringiensis (Btt), known at the time as Bt Berliner. Much of the early work done with Bt does not identify the subspecies. Btk is regi...
متن کاملHow feeding on young and old leaves affects the performance of Ascia monuste orseis (Godart) (Lepidoptera, Pieridae)
How feeding on young and old leaves affects the performance of Ascia monuste orseis (Godart) (Lepidoptera, Pieridae). In the field, immature individuals of Ascia monuste orseis (Godart), the kale caterpillars, migrate in great proportion to other regions of the host in order to complete their development; there, they find leaves of different ages and are exposed to the nutritional variation of ...
متن کاملComplete Genome Sequence of Bacillus thuringiensis subsp. kurstaki Strain HD73
Bacillus thuringiensis is a Gram-positive bacterium that produces intracellular protein crystals toxic to a wide variety of insect larvae. We report the complete genome sequence of Bacillus thuringiensis subsp. kurstaki strain HD73 from the Centre OILB (Institut Pasteur, France), which belongs to serotype 3ab and is toxic to lepidopteran larvae.
متن کاملFacile autoplast generation and transformation in Bacillus thuringiensis subsp. kurstaki.
We describe a method for maximizing the rate of conversion of Bacillus thuringiensis subsp. kurstaki vegetative cells to osmotically fragile forms in the absence of exogenously added enzymes. Optimal generation of autoplasts occurred in 50 mM sodium acetate buffer (pH 7.0) at 37 degrees C with 10% (wt/vol) polyethylene glycol as an osmotic stabilizer. The maximum autolytic rate resulted in a co...
