Galleria mellonella as an experimental model for studying periodontopathogens

J Indian Soc Periodontol. 2020 Nov-Dec;24(6):593-596. doi: 10.4103/jisp.jisp_631_19. Epub 2020 Sep 21.

Abstract

In the present study, Galleria mellonella was evaluated as a potential infection model for periodontal bacteria, more specifically, Porphyromonas gingivalis, Fusobacterium nucleatum, and Aggregatibacter actinomycetemcomitans. All the bacteria evaluated were pathogenic to G. mellonella, causing their death in a concentration-dependent manner, and a decrease in their hemocyte count. Moreover, it was possible to recover the bacteria from the larvae hemolymph and determine the colony-forming units per larvae. G. mellonella is an effective model that may help to better understand the host-microbe interactions in periodontics.
