ID#: 2069 Description: Plague infected male Xenopsylla cheopis 28 days after feeding on an inoculated mouse.

During feeding, the flea draws viable Y. pestis organisms into its esophagus, which multiply and block the proventriculus just in front of the stomach, later forcing the flea to regurgitate infected blood unto the host when it tries to swallow.
