Prolonged pre-incubation increases the susceptibility of Galleria mellonella larvae to bacterial and fungal infection.
Galleria mellonella larvae are widely used for assessing the virulence of microbial pathogens and for measuring the in vivo activity of antimicrobial agents and produce results comparable to those that can be obtained using mammals. The aim of the work described here was to ascertain the effect of pre-incubation at 15°C for 1, 3, 6 or 10 weeks on the susceptibility of larvae to infection with C...
متن کاملImmunity 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...
متن کاملA Histological Procedure to Study Fungal Infection in the Wax Moth Galleria Mellonella
The invertebrate model Galleria mellonella is a widely used factitious host to study the microbial pathogenesis in vivo. However, a specific procedure for the recovery and the processing of the infected tissues, important for a better understanding of the host-pathogen interactions, has not been reported to our knowledge. In the present study we describe a new procedure of fixation and processi...
متن کاملLegionella 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 کاملNew to Galleria mellonella
EditoriAL Pathogens and their respective hosts interact closely leading to the host–pathogen framework response that could result in different outcomes that range from pathogen elimination to death of the host. To improve our ability to propose new measures that promote pathogen elimination and prevent host death, we need to have a comprehensive understanding of this interaction. Generally , mo...
