Figure 3.

Proportion of anti-B. tropicalis IgE antibodies binding to carbohydrate epitopes in individuals with and without positive skin prick test (SPT) results. The values represent the reduction in the binding to the B. tropicalis extract, in an ELISA, of the antibodies, caused by pre-treating the antigen by metaperiodate/borohydride, as explained in the Methods section. Each symbol represents the result obtained from an individual serum. The horizontal lines represent the median value of the group results. There was no statistically significant difference between the two studied groups (p > 0.05, Mann-Whitney U test).
