Nonsusceptibility of Lizards Exposed to the Entomopathogen Bacillus sphaericus.
نویسنده
چکیده
Tropical and subtropical lizards of the genus Anolis were exposed to Bacillus sphaericus Neide strain 1593-4, which has been proposed as a safe entomopathogen specific for mosquitoes. No deleterious effects were observed in lizards exposed to live bacteria through intraperitoneal injection or aerosol spray. Bacteria were lost quickly from lizard livers but were detectable at least 37 days after intraperitoneal injection.

To evaluate the role of wild promoter of L-phenylalanine dehydrogenase (PheDH) gene, referred to as pdh, from Bacillus sphaericus in expression, cloning of pdh gene in Bacillus subtilis was performed. The whole pdh gene was cloned in pHY300PLK shuttle vector and amplified, construct (pHYDH) then transformed in B. subtilis ISW1214 and E. coli JM109. The pdh endogenous promoter presented no effec...

Cloning and expression of the L-phenylalanine dehydrogenase gene, from B. sphaericus in E. coli were done. The gene was cloned in the vector pET16b and transformed into E. coli BL21 (DE3). The functional form of the L-phenylalanine dehydrogenase enzyme was purified by affinity purification techniques, taking advantage of the ability of this enzyme to bind to the nucleotide site affinity dye, Re...
متن کاملTolerance to individual and joint effects of arsenic and Bacillus thuringiensis subsp. israelensis or Lysinibacillus sphaericus in Culex mosquitoes.
Arsenic contamination of global water supplies has come to the forefront in policy decisions in recent decades. However, the effects of arsenic on lower trophic levels of insects inhabiting contaminated ecosystems are not well understood. One approach to document both acute and sublethal effects of toxicants like arsenic is to assay them in combination with microbial pathogens to evaluate shift...
متن کاملEvolution of resistance to the Bacillus sphaericus Bin toxin is phenotypically masked by combination with the mosquitocidal proteins of Bacillus thuringiensis subspecies israelensis.
Two insecticidal bacteria are used as larvicides to control larvae of nuisance and vector mosquitoes in many countries, Bacillus thuringiensis ssp. israelensis and B. sphaericus. Field studies show both are effective, but serious resistance, as high as 50 000-fold, has evolved where B. sphaericus is used against Culex mosquitoes. To improve efficacy and deal with even greater potential problems...
متن کاملPhylogeny of Bacillus sphaericus-like organisms.
The mesophilic round-spored bacteria embrace four species, namely Bacillus sphaericus, Bacillus fusiformis, Bacillus silvestris and Bacillus pasteurii. Although not displayed by all strains, mosquito pathogenicity is a noteworthy characteristic of B. sphaericus sensu lato. Phylogenetic analysis based on 16S rDNA sequences from 58 strains identified as B. sphaericus was used to examine the genet...
