【Abstract】 Objective] To prove the existence of infectious focus area of Lyme through the investigating of the forestry residents and the spreading vector in Man Shan of south Hunan province. [Methods] An investigation was selected in Man-Shan forestry area IFA was used to examine serum and DFA was used to identify the etiology of vector ticks.[Result] The result of 395 serum showed that the intectious rate of residents of lyme disease was 6 33%, there was no difference in occupational population (χ 2=2 528,P>0 500). A total number of 212 ticks were examined, which showed Boophilis Condatus was the (prominent) prevailing species, and the infective rate of Borrelia Burgdorferi was 15%(3/20) in the gut of Boophilus Microphus.[Conclusion] It was the first time that the infectious forus area of Lyme disease was confirmed in the forestry region of Man shan-the south of Hunan province.更多还原
