Legionella pneumophila pathogenesis in the Galleria mellonella infection model.
Legionella pneumophila is a facultative intracellular human pathogen and the etiological agent of severe pneumonia known as Legionnaires' disease. Its virulence depends on protein secretion systems, in particular, the Dot/Icm type IV secretion system (T4SS), which is essential to establish a replication-permissive vacuole in macrophages. The analysis of the role of these systems and their subst...
متن کاملUse of Galleria mellonella as a Model Organism to Study Legionella pneumophila Infection
Legionella pneumophila, the causative agent of a severe pneumonia named Legionnaires' disease, is an important human pathogen that infects and replicates within alveolar macrophages. Its virulence depends on the Dot/Icm type IV secretion system (T4SS), which is essential to establish a replication permissive vacuole known as the Legionella containing vacuole (LCV). L. pneumophila infection can ...

متن کاملThe effect of Galleria mellonella hemolymph polypeptides on Legionella gormanii.
Among Legionella species, which are recognized to be pathogenic for humans, L. gormanii is the second prevalent causative agent of community-acquired pneumonia after L. pneumophila. Anti-L. gormanii activity of Galleria mellonella hemolymph extract and apolipophorin III (apoLp-III) was examined. The extract and apoLp-III at the concentration 0.025 mg/ml caused 75% and 10% decrease of the bacter...
متن کاملThe insect Galleria mellonella as a powerful infection model to investigate bacterial pathogenesis.
The study of bacterial virulence often requires a suitable animal model. Mammalian models of infection are costly and may raise ethical issues. The use of insects as infection models provides a valuable alternative. Compared to other non-vertebrate model hosts such as nematodes, insects have a relatively advanced system of antimicrobial defenses and are thus more likely to produce information r...
