Objective: To investigate and understand the background of population and growth of mouse-shaped animals and their parasites in Zhanjiang port. Method: cage catch method. Results: There were 8 species, 4 genera and 2 families, 2 orders and 2 species. The parasites mainly included 3 species: 3 species, 3 genera and 3 species, 4 species, 2 genera and 3 genera, 2 species, 6 genera and 9 species. Annual animal flea, leather mite, chigger mite rates were 33.2%, 53.3%, 45.0%; the highest infection rate of animals were Rattus flavipectus, Rattus rat and mouse. Annual animal dyed fleas, leather mites, chigger mite index were 0.8, 4.8, 32.9; the highest infection index animals were Rattus norvegicus, Rattus rat, Banded rat. The highest and lowest monthly infection rates of fleas, leather mites and chigger mites were 4, 8 and 11 months and 6, 7, 7 and 12 months respectively. The infection indices were 4, 8, 8 and 3, 7 and 12 respectively. Conclusion: It is possible to have the plague foci and the natural epidemic foci of scrub typhus.
