Moulds- ubiquitous micromycetes can cause mycoses in humans and animals including: chronic bronchitis, asthma, hypersensitive pneumonitis and aspergillosis. The occurrence of air spora concentrations of outdoor environment depend on numerous factors including time of day, meteorological factors, seasonal climatic factors, and type of vegetation. Comparative research was carried out on presence and variation in occurrence of fungal genera in air and plant samples collected from three climates in Croatia (Continental part, Primorje, Dalmacija) during 5 months (January, February, May, June, November) (1998). The sampling method employed in this study was exposure of 150 Sabouraud Petri agar plates with antibiotics to the air for 10 min. and by placing each plant sample (N=1500) on same Petri agar plates. Cladosporium (65.3-74%), Penicillium (4.43- 13.9%), Alternaria (2-4.7%), and Mycelia sterilia (7.4-15%) were the most prevalent fungi in air of all three climate area but with lower occurrence in Mediterranean climate, while Fusarium (20.3-36.2%), was the most prevalent fungal genera in plant samples especially in Modest Continental climate. Monthly occurrence of fungal spora in dependence on temperature and relative humidity during 5 months, point at lower number of spora in January and February, and increased in May and June in Modest Continental climate and Primorje. In Dalmacija the number of spora was significantly lower (p<0.05) during the same time of sampling. The climate factors and presence of vegetation that produce essential oils with fugistatic and fungicide activity can be the reason for reduce fungal spora of outdoor environment in Mediterranean climate. Since the many species of moulds were known to be allergenic, reduction of fungal spora in Mediterranean climate can have important role in climotherapy of respiratory diseases.
