Otitis externa

Description:The outer ear canal expression of ABH human blood group antigens has been analyzed with a standardized routine histological procedure by monoclonal antibodies in the case of blood groups A and B, and a corresponding lectin in the case of blood group 0, respectively. In all 20 cases the blood groups were histochemically confirmed. Furthermore, Pseudomonas aeruginosa-specific inhibition experiments were performed with different sugar solutions as well as A-like substance incubating outer ear canal tissue sections with P. aeruginosa strain (No. 60) presenting lectin specificity for N-acetyl-galactosamine (GalNAc). P. aeruginosa lectins with GalNAc specificity apparently adhere to GalNAc as terminal blood group A determinant and indicate that patients presenting with blood group A may have a genetic predisposition to this form of otitis externa.
