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...

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 establi...

Fresh, frozen sections of the photoreceptor layer of the compound eye of the moth Galleria have been examined by microspectrophotometry, using 4 times 8 mum measuring beams that sampled from approximately two to four rhabdoms. The principal visual pigment absorbs maximally at 510 nm (P510), and on irradiation is converted to a thermally stable, pH-insensitive metarhodopsin with lambda max at 48...

The design and evaluation of antimicrobial activities an isonitrosomalononitrile silver(I) salt was reported. This highly stable water-soluble silver shows Minimum Inhibitory Concentrations (MIC) values ranging from 0.15 to 5 µg/mL towards both sensitive resistant Gram-positive negative bacteria. Furthermore, this has been investigated for its ability treat a S. aureus infected Galleria mellone...

Hypothesis: Under exploitative competition, unrelated parasites should reproduce at a faster rate than related parasites. Organisms: The parasitic nematode Steinernema carpocapsae and the insect host Galleria mellonella. Methods: We created ten replicate lines each of high-migration (unrelated) and low-migration (related) nematode populations, and allowed them to evolve for 20 host passages. Re...
