R. flavipectus disposed at flat form T1 and R. norvegicus disposed at store area. The only flea species found at the surveillance site was X.cheopis. Bacterial isolation of 236 specimens of liver and spleen, and ELISA tests of 180 blood samples were performed. All of the specimens were negative to Yersinia pestis.
