[Significance of passive hemagglutination and its prospectives in lymphatic filariasis].
The authors analyze the data concerning 219 sera, that they have tested in passive hemagglutination, with as antigen a Dirofilaria immitis proteic extract, in French Polynesia. Besides its light sensitivity, this method does appear very interesting. It points out: --First, that there is a gaussian distribution of the results found at various dilutions, both by "filarian" and "non filarian" people. Therefore, this distribution is a feasible and practical parameter for evaluation of the Filariasis transmission in different populations. --On the other hand, that there is an inverse correlation between the presence of microfilaria in the blood and the level of immunological response for lymphatic Filariasis.
