چکیده

The number of studies using G. mellonella as a model host for human pathogens has increased significantly in the last few years. Important studies were published from different countries for evaluating the pathogenesis of bacterial and fungal infections and for exploring the host defenses against pathogens. Therefore, standardized conditions for the use of G. melonella larvae need to be established. Recent research showed that the deprivation of G. mellonella larvae of food during the experiment caused a reduction in immune responses and an increased susceptibility to infection, suggesting that incubating of larvae in the presence or absence of nutrition may affect the results and comparisons among different laboratories.

Immunity of the greater wax moth Galleria mellonella.

Investigation of insect immune mechanisms provides important information concerning innate immunity, which in many aspects is conserved in animals. This is one of the reasons why insects serve as model organisms to study virulence mechanisms of human pathogens. From the evolutionary point of view, we also learn a lot about host-pathogen interaction and adaptation of organisms to conditions of l...

Expression of the insect metalloproteinase inhibitor IMPI in the fat body of Galleria mellonella exposed to infection with Beauveria bassiana.

The inducible metalloproteinase inhibitor (IMPI) discovered in Galleria mellonella is currently the only specific inhibitor of metalloproteinases found in animals. Its role is to inhibit the activity of metalloproteinases secreted by pathogenic organisms as virulence factors to degrade immune-relevant polypeptides of the infected host. This is a good example of an evolutionary arms race between...

Galleria mellonella as a model host to study gut microbe homeostasis and brain infection by the human pathogen listeria monocytogenes.

The gastrointestinal tract in both mammals and insects is associated with microbes (collectively the microbiota), which are controlled by the intestinal immune system. These microbes regulate pathogens that can infect gut epithelial cells, and there is increasing evidence for a reciprocal relationship between beneficial and pathogenic bacteria in the gut and the intestinal immune system. Deciph...

Developing the potential of using Galleria mellonella larvae as models for studying brain infection by Listeria monocytogenes

The use of mammals for studying microbial pathogens or for assessing the efficacy of a variety of pharmaceutical agents has contributed enormously to our knowledge of microbial virulence and in the development of novel therapeutic strategies. However, despite these advances, there is a recognition that the number of mammals used in such tests must be reduced to the minimum and that alternative,...

Genome Sequence of Galleria mellonella (Greater Wax Moth)

The larvae of the greater wax moth, Galleria mellonella, are pests of active beehives. In infection biology, these larvae are playing a more and more attractive role as an invertebrate host model. Here, we report on the first genome sequence of Galleria mellonella.
