Yersinia enterocolitica strain W22703 is a human enteropathogen that is able to successfully infect invertebrates. Upon oral application to larvae of the Greater wax moth Galleria mellonella, Y. enterocolitica (light blue) colonizes the gut (right) and interacts with the epithelial cell layer. It enters the hemolymph of the insect (left) within the first 24 hours of infection where the pathogen massively proliferates due to readily available substrates that fuel its re-programmed metabolism. Bacterial cells were stained by a fluorescent Yersinia-antibody.
