Genetic relationships between sympatric populations of Bacillus cereus and Bacillus thuringiensis, as revealed by rep-PCR genomic fingerprinting

Memorias do Instituto Oswaldo Cruz, 2008
The bacterial strain Bacillus cereus is closely related to Bacillus thuringiensis, although any genetic relationship between the two strains is still in debate.

Microbial Pressure and Social Immunity: Bumble Bees Increase Brood Hygiene After Exposure to a Bacillus thuringiensis‐Based Biopesticide [PDF]

Ecol Evol
In social insect colonies, diseased or dead brood is identified and removed by workers to prevent the infection of the whole colony. Here, bumble bee larvae exposed to a bacterium (Bacillus thuringiensis ssp. aizawai (strain: ABTS‐1857)) based biopesticide were removed more frequently than wounded or untreated control larvae. This shows that bumble bee

Differentiation of Bacillus thuringiensis From Bacilluscereus Group Using a Unique Marker Based on Real-Time PCR

Frontiers in Microbiology, 2019
The efficiency of a novel biomarker (the transcriptional regulator, XRE) was tested and evaluated in differentiating Bacillus thuringiensis from Bacillus cereus group species in environmental and spiked samples based on PCR and real-time PCR. Totally 120

CRISPR-Cas9-mediated barcode insertion into Bacillus thuringiensis for surrogate tracking

Microbiology Spectrum
The use of surrogate organisms can enable researchers to safely conduct research on pathogens and in a broader set of conditions. Being able to differentiate between the surrogates used in the experiments and background contamination as well as between ...

Toxicity of Cry2 proteins from Bacillus thuringiensis subsp. thuringiensis strain T01-328 against Aedes aegypti (Diptera: Culicidae)

Arquivos do Instituto Biológico, 2018
: Bacillus thuringiensis subsp. israelensis has been used to control the Aedes aegypti (Diptera: Culicidae) mosquito larvae, the vector of virus diseases such as dengue, Chikungunya and Zika fever, which have become a major public health problem in ...

The regulatory frameworks surrounding CRISPR‐edited papaya and their impact on international commerce

Journal of the Science of Food and Agriculture, EarlyView.
Abstract The papaya tree (Carica papaya L.), native to the Americas, is cultivated in tropical regions and holds substantial economic importance, with an estimated export volume of 365 000 t in 2023. However, diseases caused by viruses, fungi, bacteria, and nematodes can lead to severe losses.

The autolytic phenotype of Bacillus thuringiensis [PDF]

Journal of Applied Microbiology, 2004
To evaluate the autolytic phenotype of Bacillus thuringiensis.The autolytic rate of 87 strains belonging to different subsp. of B. thuringiensis was examined at pH 6, 6.5 and 8.5 in different buffers under starvation conditions. At pH 6 the extent of autolysis (average in the strain collection 38.3 +/- 21.1) was strain-dependent with wide variability ...

Adaptation of Bacillus thuringiensis to Plant Colonization Affects Differentiation and Toxicity

mSystems, 2021
The Bacillus cereus group (Bacillus cereus sensu lato) has a diverse ecology, including various species that are vertebrate or invertebrate pathogens. Few isolates from the B. cereus group have however been demonstrated to benefit plant growth. Therefore,

Fitness costs associated with Vip3Aa resistance on various hosts in Helicoverpa zea

Pest Management Science, EarlyView.
Significant fitness costs associated with Vip3Aa resistance in H. zea were observed across three non‐Bt hosts. Abundant non‐Bt refuges could help limit the spread of Vip3Aa resistance in H. zea in the field. Abstract BACKGROUND Transgenic crops containing Bacillus thuringiensis (Bt) proteins are crucial for managing major agricultural pests such as the
