All 31 cases provided acute sera, 19 provided convalescent sera and 14 had viral throat/nose swabs taken.
Two sera gave non-specific fluorescence that could not be interpreted.
A week after the last dose of antigen, jirds were bled from the retro-orbital plexus and immune sera were isolated.
The rabbits were bled before the immunizations, and the sera obtained were used for control studies.
Statistical analysis of results from all sera has previously demonstrated that this seven-band pattern was significantly correlated with a toxocaral infection.
The wells were incubated for 2 h at room temperature with diluted human sera.
None of the other sera with toxocariasis, paragonimiasis, filariasis and malaria, and the ten control sera from normal parasite-free individuals produced a positive blue dot.
To assess potential cross-reactivity, sera from individuals (n 1⁄4 40) with parasitic diseases (leprosy, malaria, ascariasis) other than filariasis were used.
