Dendrogram representing the relatedness of 86 S. aureus isolated from affected skin and from nose of 64 patients with AD. (Cut-off point – 72.0 (Dice), resistance phenotypes of all examined S. aureus and additional patient’s data. The clusters were marked with the letters A-T and V-X, and the unique genotypes were marked with the letter U. Patient/s skin isolate, patient/n – nose isolate. F-female, M-male. (a) – resistance phenotypes - MRSA-methicillin resistant Staphylococcus aureus, MLSB-macrolide, lincosamide and streptogramin B resistant (MLSBc-constitutive, MLSBi-inducible), MUP-R – mupirocin resistant, TE-R- tetracycline resistant, C-R – chloramphenicol resistant. (b) additional data concerning the concomitant conditions in examined patients include psoriasis, bronchial asthma, allergic rhinitis, contact dermatitis. Lack – patients who denied the existence of hypersensitivity/conditions. (c)  number of flares in previous 6 months. (d) – exacerbations classified as moderate or strong based on the patients personal rating
