ANSWER: One study looked at the saliva of 310 persons were examined for their ability to agglutinate 33 streptococcal strains. It was found that the saliva of persons with blood group O agglutinated significantly more often streptococci than the saliva of persons with blood group A. The results demonstrated that persons of the blood group O secrete more anti-Strep immunoglobulin than those with blood group A.(1) This may be worse for type A non-secretors since the elaboration of free blood type antigen in saliva and mucous is thought to inhibit the growth of Streptococcus.(2)

Some idea would include having the child take 1 Deflect A capsule (available from North American Pharmacal) and mix it with water so as to make a mouthrinse. Have the child rinse their throat 2-4 times daily (this has the effect of making the child, in essence, a 'secretor'.

Other ideas are to use the herb Golden Seal, (Hydrastis canadensis) which has mild anti-Strep effects, and/or a gentle immune tonic, like North Americans ARA6.
