丝虫病实验性传播指数最初由Kart-man(1954)提出,其后经Wharton(1957,1960)改进,称Wharton指数,其定义是当1μl人宿主血中的微丝蚴(mf)数为1时,每只蚊虫体内的感染期幼丝虫数。该指数在过去的30年间被丝虫病研究人员广泛采用。但Kartman或Wharton指数所依据的是预期被吸血蚊吸入的mf理论数,而不考虑在吸血期间及其后可能影响mf数量的各种因素。为弥补这一缺点,进行了人宿主指端血, The Filariasis Experimental Propagation Index was first proposed by Kart-man (1954) and later refined by Wharton (1957, 1960) as the Wharton index, which is defined as the number of microfilariae (mf) in 1 μl of human host blood is 1, each mosquito in vivo infection number of young filariasis. The index has been widely adopted by filariasis researchers for the past 30 years. But the Kartman or Wharton index is based on the number of mf theories expected to be inhaled by mosquitoes, regardless of the factors that may affect the amount of mf during and after blood-sucking. To make up for this shortcoming, carried out the finger host blood,
