Re: Some of the test results back from the lab

this is a common misconception in the industry regarding eosinophil counts. I too have endured this. If its any consilation they weren't anymore concerned when my eosinophils were skyhigh years ago.

Low eosinophil count might be immunosuppressions but also part of this is that eosinophils react more acutely to migrating larvae which occurs more commonly in the acute infection phase. Adult parasites are much more evasive immunologically speaking, hence less eosinophil reaction.

Antibodies are produced by plasma cells (http://en.wikipedia.org/wiki/Plasma_cell). I know initially these also increase with parasitic infections to produce specific antibodies to the pathogen as well as memory cells. One of the classes you may have heard of is the IgE antibody which are responsible for a strong immunological reaction, including degranulation of mast cells (http://en.wikipedia.org/wiki/Mast_cell) which contribute to allergy symptoms. This may be why many experience allergy symptoms after parasite infection.

All of these mechanisms interact, so suppression of one is likely to effect the others as well.
