Cross-Reaction between the Crude Hydatid Cyst Fluid Antigens of Human and Animals Origin in Response to Human IgG Class and Subclasses

Table 11

The OD ratio of IgG calass, IgG subclass, and IgE of 30 human sample sera to crude HCF antigens of cattle, Ag B, mice, sheep, and human.

Ig/Ag origin	Cattle	Ag B	Mice	Sheep	Human
IgG	5.3	3	5.8	2.8	7.4
IgG2	2	4.5	1.2	2.6	2.8
IgG3	3.4	2.75	0.75	2.3	1.4
IgG4	10.2	9	7.25	5	10.5
IgE	0.64	3.75	1.1	2.6	8.2

The OD ratio was calculated as mean OD value for each antigen divided by the cut-off of that antigen.
