Listeria monocytogenes the causative agent of the foodborne disease listeriosis in humans often involves fatal brainstem infections leading to meningitis and meningoencephalitis. We recently established the larvae of the greater wax moth (Galleria mellonella) as a model host for the investigation of L. monocytogenes pathogenesis and as a source of peptides exhibiting anti-Listeria-activity. Her...

OBJECTIVES Epidermicin is a novel antimicrobial peptide that has potent activity against Gram-positive pathogens, including methicillin-resistant Staphylococcus aureus, and it may have potential for use in therapy for infections caused by these bacteria, though in vivo efficacy needs to be demonstrated. Galleria mellonella larvae have recently been introduced as an alternative in vivo model to ...

Few studies have addressed the role of the sexes in the emergence and dispersal of entomopathogenic nematodes from host insects. Individuals of two isolates of Steinernema feltiae, UK76 and SBIl, emerging from Galleria mellonella cadavers were classed as Non-Dispersed (remaining on the cadaver for up to nine days) and Dispersed (actively moving away from the cadaver). Sex ratios within both cla...

Pathogenic effect of an indigenous entomopathogenic nematode, Heterorhabditis indica and commercial biopesticides of three fungal pathogens (M. anisopliae, B. bassiana and T. viride), one antagonistic bacteria (P. fluorescence), and two neem based biopesticides (Neem and Nimor) were tested on the Greater wax moth, Galleria mellonella larva under laboratory condition. The efficacy of the biopest...

The virulence of Yersinia pestis KIM6+ was compared with multiple isolates of Yersinia pseudotuberculosis and Yersinia enterocolitica toward larvae of the greater wax moth Galleria mellonella. Although Y. pestis and Y. pseudotuberculosis were able to cause lethal infection in G. mellonella, these species appeared less virulent than the majority of Y. enterocolitica strains tested. Y. pestis sur...

The resources available to an individual in any given environment are finite, and variation in life history traits reflect differential allocation of these resources to competing life functions. Nutritional quality of food is of particular importance in these life history decisions. In this study, we tested trade-offs among growth, immunity and survival in 3 groups of greater wax moth (Galleria...
