Yersinia pestis induces, resists and then consolidates the formation of a bactericidal matrix in the flea’s proventriculus, which hastens its transmission to the mammalian host. In this fluorescence image, myriad of GFP+ Y. pestis are entrapped in a mass fulfilling the anterior spineless region and the spined region (that autofluoresces in yellow) of the proventriculus. Here, the mass also extends in the esophagus. Dewitte et al
