Argentinean Bacillus thuringiensis strains exhibiting distinct morphology of their parasporal crystals
Peralta, Cecilia; Sauka, Diego Herman; Marozzi, Antonela Alejandra; del Valle, Eleodoro Eduardo; Palma, Leopoldo (Asociación Argentina de Microbiología, 2021-10)Bacillus thuringiensis is a Gram-positive and sporulated bacterium exhibiting insecticidal activity against a wide range of insects.3 During sporulation, this bacterium produces a number of different proteins forming ... -
Bacillus thuringiensis and their endophytic capabilities
Sauka, Diego Hernan (2017-07)The main characteristic of Bacillus thuringiensis is that during sporulation produces a parasporal inclusion formed by one or more proteinaceous bodies that exhibit insecticidal activity upon ingestion by susceptible ... -

It carries 7 insecticidal genes: 3 cry8 copies previously ... -
Diversity and distribution of lepidoptera-specific toxin genes in Bacillus thuringiensis strains from Argentina
Sauka, Diego Hernan; Benintende, Graciela Beatriz (2017-05)A total of 268 Bacillus thuringiensis strains obtained from different sources of Argentina were analyzed to determine the diversity and distribution of the cry1, cry2, cry8, cry9 and vip3A genes encoding for lepidopteran-specific ... -
Draft Genome Sequence of Bacillus thuringiensis INTA Fr7-4
Navas, Laura Emilce; Berretta, Marcelo Facundo; Ortiz, Elio Maximiliano; Sauka, Diego Hernan; Benintende, Graciela Beatriz; Zandomeni, Ruben; Amadio, Ariel (2017)We report here the complete annotated 6,035,547-bp draft genome sequence of Bacillus thuringiensis INTA Fr7-4. This strain contains three cry8 and two vip1 and vip2 insecticidal toxin genes. -
Factores de virulencia de Bacilus thuringiensis y su utilización para el control de coleópteros de alto impacto en el sector agropecuario
Perez, Melisa Paula (Facultad de Farmacia y Bioquímica, Universidad de Buenos Aires, 2017-03)La necesidad de contar con herramientas seguras y efectivas para el manejo de plagas, alternativas o complementarias a los insecticidas químicos, estimula el interés en usar entomopatógenos como agentes de biocontrol. ... -
Nematicidal effect of an Argentine strain of Photorhabdus laumondi laumondi (Enterobacteriaceae) on the free-living nematode Panagrellus redivivus (Rhabditidae: Panagrolaimidae)
Salas, Augusto; Achinelly, María Fernanda; Sauka, Diego Hernan (Elsevier, 2021-01-01)Bacteria with nematicidal effects have attracted interest as biocontrol agents of pests and diseases due to their relatively low environmental impact compared to chemical management strategies1. The damage they cause to ... -
New entomopathogenic strain of Bacillus thuringiensis is able to solubilize different sources of inorganic phosphates
Sauka, Diego Hernan; Piccinetti, Carlos Fabian; Vallejo, Daniela Adriana; Onco, Maria Ines; Perez, Melisa Paula; Benintende, Graciela Beatriz (Elsevier, 2021-04-01)Phosphate-solubilizing strain INTA 293-1 from a soil sample of Corrientes province (Argentina) was identified as Bacillus thuringiensis based on its faculty to produce crystalline inclusions during sporulation and 16S rDNA ... -
