Abstract: 

Background: In recent years there have been considerable cases of respiratory tract disease with high morbidity among Hajj pilgrims. Therefore, prevention and control of the disease will be necessary and needed to know its etiologic agent. It is obvious that environmental microbial agents have important causative role in respiratory tract diseases. Among them fungi include a diverse array of organisms which are found widely in nature. The spores of fungi spread through the air and remain airborne for prolonged periods. Fungi in the air are being proposed as a cause of adverse health effects and exposure to fungi has been reported to cause infections, allergies and even toxic effects. The present study was undertaken to determine the role of fungi as presumptive etiologic agents of respiratory tract disease in Iranian Hajj pilgrims during Hajj 1383 (2005).
Materials and Methods: This study was carried out by culture of environmental specimens which obtained from the Iranian pilgrims' campus in Mecca, Medina, Mina and Arafat for detection of fungal elements and using serological tests for diagnosis of fungal infections in 146 Hajj pilgrims. These tests were done on two blood samples within 8 weeks intervals in each case.
Results: Culture of environmental specimens totally yielded 3521 colonies of 23 different genus and species of fungi. Isolated organisms consisted in filamentous saprophytic fungi 79%, filamentous pathogenic fungi (dermatophytes) 3.6% and yeasts 17.4%. Aspergillus spp. were the most common (43.4%) isolated fungi in this study. The results of counter-immuno-electrophoresis and latex agglutination tests that were used for diagnosis of aspergillosis, candidiasis and cryptococcosis among the pilgrims all were negative.
Conclusion: Although the results of this study don't implicate the role of fungi as causative agents of respiratory tract disease in Hajj pilgrims. But since exposure to fungi cause different adverse health effects and clinical diagnosis of them is difficult and because the fungi have effects on immune system and predispose the patients for other infections or fungal diseases manifestate as secondary infections, further study VDI.63.NDIYI.ear 2DD6I will be needed if the respiratory disease of Hajj pilgrims will be continues in future 152 years.
