【Abstract】 Objective To study the species composition of rodents and the role on schitosomiasis transmission in Yunan province.Method The routine method was taken to observe whether the rodents were infected with schitosoma japonicum .Results 3435 rodents were captured in schitosomiasis area.They were classified into 19 specoies, 11 genera,6 families and 4 orders.The dominant species were Rflavipectus and Rnorvegicus , which accounted for 45 09% and 28.27% respectively.Among 3411 rodents being tested, 32(5 species) were infected with schitosoma japonicum ,the positive rate of stool was 0 94% and EPG(X) was 5 78 in whole investigated area, but 0 15% and 0 05 in mountainous basin region,1 97% and 13 39% in mountainous valley region.Conclusion The transmission of schitosomia sisby rodents is not notable in Yunan province,but it possesses epidemiological significance in some areas of mountainous valley region.更多还原
