{Reference Type}: Journal Article {Title}: Galleria mellonella as a Good Model to Study Acinetobacter baumannii Pathogenesis. {Author}: Tao Y;Duma L;Rossez Y; {Journal}: Pathogens {Volume}: 10 {Issue}: 11 {Year}: Nov 2021 14 {Factor}: 4.531 {DOI}: 10.3390/pathogens10111483 {Abstract}: The invertebrate model, Galleria mellonella, has been widely used to study host-pathogen interactions due to its cheapness, ease of handling, and similar mammalian innate immune system. G. mellonella larvae have been proven to be useful and a reliable model for analyzing pathogenesis mechanisms of multidrug resistant Acinetobacter baumannii, an opportunistic pathogen difficult to kill. This review describes the detailed experimental design of G. mellonella/A. baumannii models, and provides a comprehensive comparison of various virulence factors and therapy strategies using the G. mellonella host. These investigations highlight the importance of this host-pathogen model for in vivo pathogen virulence studies. On the long term, further development of the G. mellonella/A. baumannii model will offer promising insights for clinical treatments of A. baumannii infection.
