ABSTRACT
The distribution of pollen antigens of an area depends on geographic situation, climatic factors and vegetation. Geographic situation of examined area is in latitude from 42.5 degrees (Dubrovnik) to 45.5 degrees north (Rijeka), the climate is Mediterranean and botanically it is Eumediterranean area. In allergologic out-patient departments of Dubrovnik, Split, Sibenik, Zadar, Pula and Rijeka, 300 patients with pollinosis have been tested by the application of the prick method of group allergens of grass, tree and weed pollen, particularly of Parietariae (pellitory) pollen. The object of the investigation was to find out which pollen antigen is actual for the Adriatic area and distribution of Parietariae pollen, regarding the fact that it was almost the only cause of pollinosis in the south part of the Adriatic coast (Dubrovnik), Ninety healthy persons were also examined, 15 in each out-patient department, being the control. The results show that grass pollen is actual allergen in the north and middle Adriatic area, while in the south Adriatic it is without any importance. The number of people oversensitive to trees and weeds pollen is low. The oversensitiveness to Parietariae pollen appears all along the coast, its number decreasing from the south to the north. It is concluded that grass pollen is the main cause of pollinosis, in the area of the Croatian littoral and Istria, important in south and central Dalmatia and almost without importance in south Dalmatia. Parietariae pollen is actual allergen all along the coast, being almost the only cause of pollinosis in south Adriatic area.
