Abstract

The Enterococci, mainly Enterococcus faecalis and E. faecium, are ubiquitous members of the human gastrointestinal tract consortia but also a leading cause of opportunistic infections. The global rise in human-associated enterococcal infections, often caused by multidrug resistant strains, highlights an urgent need to identify the bacterial factors contributing to its pathogenicity such that new therapies can be devised. The use of the Galleria mellonella (greater wax moth) larvae, commonly known as wax worm, as a model to study host-pathogen interactions has allowed the identification and characterization of numerous bacterial factors that contribute to disease in humans, serving both as an alternative and complementary approach to mammalian models. Here, we describe the methods for using G. mellonella to characterize the virulence factors of E. faecalis.
