Questions About Specific Health Issues

Type A and Strep Throat


My son (A+) gets Strep throat 3-4 times per winter. We did have him secretor typed by Dr. Kruzel and he is a non-secretor. My daughter (O+) has never contracted Strep. Is there any blood type distinctions with strep throat?


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.

The Ask Dr. D'Adamo internet advice column ran from 1996 to 2009, at which time Dr. D'Adamo's teaching and programming responsibilities no longer allowed him to devote time and resources to directly answering visitor questions. However we've recently reorganized this treasure-trove of material and made it again available to his readership. He occasionally posts new entries. These are marked with a NEW tag.

Rather than trying to make a one-size fits all blend, Dr. D'Adamo specially formulated his Polyvite multivitamins for each blood type, giving people the specific vitamins that help their body best.
