This study comprises 2 groups of children; allergic (18) and non-allergic (36), having undergone tonsillectomy, adenoïdectomy or both. The humoral immunity profile' bacteriology and neutrophile and eosinophile cell populations of the lymphoid tissues removed were compared. No significant difference was brought into evidence. The bacteriology of the two groups did however show a preponderance of Haemophilus influenzae. This would appear to be in contradiction to the generally accepted theories.
