Activation of MAP kinase pathways in Galleria mellonella infected with Bacillus thuringiensis.
We followed changes in the level of phospho-MAP kinases in the greater wax moth Galleria mellonella after infection with Bacillus thuringiensis. We observed an enhanced level of phosphorylated p38 and JNK in fat bodies of the infected larvae. In hemocytes, injection of B. thuringiensis caused the highest increase in phospho-JNK, however, all pathways were activated after aseptic injection. We r...
متن کاملPlasmid transfer between strains of Bacillus thuringiensis infecting Galleria mellonella and Spodoptera littoralis.
To determine the possibility of plasmid transfer occurring between strains of Bacillus thuringiensis in infected lepidopterous larvae, Galleria mellonella and Spodoptera littoralis were infected with two or more strains of B. thuringiensis and the resulting bacteria from the dead insects were examined for plasmid transfer. Transfer rates of plasmids coding for crystal production and tetracyclin...
متن کاملImmuno-physiological adaptations confer wax moth Galleria mellonella resistance to Bacillus thuringiensis
Microevolutionary mechanisms of resistance to a bacterial pathogen were explored in a population of the Greater wax moth, Galleria mellonella, selected for an 8.8-fold increased resistance against the entomopathogenic bacterium Bacillus thuringiensis (Bt) compared with a non-selected (suspectible) line. Defense strategies of the resistant and susceptible insect lines were compared to uncover me...
متن کاملContributions of cellular and humoral immunity of Galleria mellonella larvae in defence against oral infection by Bacillus thuringiensis.
In this study the cellular and humoral immune reactions of the Greater wax moth Galleria mellonella have been investigated during bacterial infection caused by oral administration of Bacillus thuringiensis. Two different dose strengths were investigated to assess the contribution of immune parameters to induced Bt resistance. Low-dose (sublethal LC15) infection resulted in significantly elevate...
متن کاملNew to Galleria mellonella
EditoriAL Pathogens and their respective hosts interact closely leading to the host–pathogen framework response that could result in different outcomes that range from pathogen elimination to death of the host. To improve our ability to propose new measures that promote pathogen elimination and prevent host death, we need to have a comprehensive understanding of this interaction. Generally , mo...
