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. They reported negative results when the patients' own sera or other patients' sera were used. As for the older individuals, sample no. 32 lost binding activity towards chimeric protein no. 9, but most sera did not. In total, 4943 (48n9 %) sera were from males and 5175 (51n1 %) from females. The search for gastrointestinal nematode vaccine candidates has so far been based largely on immunoscreening with sera from infected animals. No correlation was found, however, between endemicity and specific antibody levels in positive sera. Again, pre-immune sera as a negative control did not show any reaction (data not shown). A bacterially expressed recombinant protein was highly reactive to the sera of patients with clonorchiasis. See all examples of serum These examples are from corpora and from sources on the web.
