Seroprevalence of toxocariasis in Lebanon: a pilot study.

abstract：:A double antibody sandwich ELISA technique has been developed for detection of antigens of African trypanosomes present in the sera of infected mammals. The assay uses a high titre, high affinity rabbit antiserum made to purified membranes of procyclic trypanosomes as "capture" reagent and a mixture of three biotin-la...
