Effect of P. brasiliensis gp43 treatment with sodium metaperiodate on ELISA results^a

Serum sample	% Decrease in absorbance or AI for:
	Total IgG	IgG1	IgG2	IgG3	IgG4
IDneg	56b	56b	63c	42	25
IDpos
AF	15	21	51c	26	22
JF	15	24	23	34	9

^aAssays were performed with serum samples from ID^neg patients and ID^pos patients (AF and JF of PCM). The data represent the decrease in the absorbance at a 1:800 dilution (OD at 492 nm) for total IgG and the AI for IgG subclasses after treatment of P. brasiliensis gp43 with sodium metaperiodate.

^bThe P value was ≤0.05 for a comparison with the AF or JF group.

^cThe P value was ≤0.05 for a comparison with the JF group.
