Methods Mice were caught by night cage - caught . Rat and flea were identified after flea being caught from living rats. Collecting the serum samples from rats, and detected the F1 antibody with RIP method. Results 121 rat -like animals were caught from 20 surveillance sites, being identified to 2 orders, 2 families, 3 genera and 4 species. The capture rate was 9. 20%. We caught 265 parasitical fleas from rats, the fleas carrying rate of mice was 56. 64% and the index of fleas inflection among the mice is 2.43. F1 antibody was detected by RIP from 120 rat sera samples, the results were all negative.
