[目的 ]了解残存微丝蚴血症者在自然条件下的动态变化 ,为消灭丝虫病提供依据。 [方法 ]于 1994— 2 0 0 1年按丝虫病常规采血检查。捕蚊管吸捕人房致倦库蚊并解剖镜检。[结果 ]人群微丝蚴率 1994年为 0 .5 7% ,2 0 0 1年 0 .39% ;血微丝蚴密度逐年下降 ,而 1999年 2例复阳 ,2 0 0 1年 1例阴性 ,1例密度 14条。8年捕获致倦库蚊 30 98只 ,阳性蚊 12只 ,蚊体内幼丝虫 4 3条。 [结论 ]8年连续观察 ,残存班氏微丝蚴血症在自然条件下 ,微丝蚴密度可逐渐降低直至转阴 ,滋生新的传染源机会极小
[Objective] To understand the dynamic changes of residual microfilaremia in natural conditions and provide the basis for the elimination of filariasis. [Method] The routine examination of filariasis in 1994-2001 was performed. Catching mosquito tube catches the human body Culex quinquefasciatus and dissecting microscopic examination. [Results] The population microfilaria rate was 0.57% in 1994 and 0.39% in 2001. The density of blood microfilaria decreased year by year, while in 2 cases of Fuyang in 1999 and 1 case in 2001 Negative, 1 case of density 14. In 2008, 30 98 Culex pipiens pallens, 12 mosquito positive mosquitoes and 43 mosquito larvae were captured. [Conclusion] After 8 years of continuous observation, the remaining Bancrofti microfilariae in natural conditions, microfilaria density can be gradually reduced until the negative, the chance of breeding new sources of infection is minimal
