SUMMARY

KEYWORDS

Mango has become one of the most popular tropical fruits. It is cultivated in more than 1000 strains. In the present study the four most frequently consumed varieties (Eden, Ngowe, Osteen and Tommy Atkins) cultivated in different continents were examined. In order to identify IgE binding allergens and determine mutual cross-reactivities of the varieties immunoblot and enzymeallergosorbent test (EAST) inhibition were performed. Seven sera from patients with sensitization to mango fruit were used. All four varieties shared at least five allergens with Mr of approximately 14, 30, 40, 43 and 67 kDa. Results of EAST inhibition elucidated almost the same inhibition curves and 50%-inhibition values for each variety. In conclusion it could be shown that there were no significant differences in allergenic potency among the four mango strains.
