Abstract

Background & aim: Indoor air contains a wide variety of Bioaerosols. The presence of Bioaerosols in the air can affect human health. Transmission of Bioaerosols may cause nosocomial infections that affect all health, economic and social aspects of one's life. Therefore, the aim of the present study was to determine the density and type of Bioaerosols in the air of Imam Sajjad Hospital of Yasuj. Methods: the present cross-sectional descriptive study was conducted in 4 sections in different classes of Imam Sajjad Hospital of Yasuj. 240 specimens were sampled by active sampling method using a Quik Tic Pump 30 sampler at a flow rate of 28. 3 liters per minute for 2 consecutive months for 4 consecutive months from August to November 2015 on tryptic agar medium and Saber-dextrose agar were collected for Bacteria and Fungi, respectively. The specimens were incubated for 48 hours at 37° C for Bacterial culture and 70 to 120 hours incubated at 25-27 ° C for the Fungi. It was reported in CFU/ m3 for each Bioaerosols. Data were analyzed using statistical tests. Results: The results indicated that Staphylococcus Bacteria (76. 57%), Bacillus (79. 36%), Nocardia (23. 4%), Micrococcus (0. 68%), Streptococcus (0. 38), Corynebacterium (0. 12%) and Enterococcus (0. 04%) were the most frequent to the lowest percentage, respectively. The highest and lowest number of Fungi observed in Imam Sajjad Hospital of Yasuj and their prevalence were Rhizopus (39. 71%), Penicillium (32. 47%), Yeast (18. 57%), and Alternaria (3. 69%), respectively. ), Ascoliolaris (0. 67%), Cladosporium (0. 43%), and Trichophagygomes (0. 23%). The highest Bacterial contamination in postnatal care was 531. 14 CFU/ m3and the least contamination in postnatal care was in fungal Bioaerosols of 114. 47 CFU/ m3 of air. The mean air pollution of the studied sections for Bacterial and fungal Bioaerosols was 24 and 125. 78 CFU/ m3, respectively. Conclusion: According to the obtained results, microbial quality of air in Imam Sajjad Hospital was not desirable. High density of patients, hospital staff and patient companions in wards, lack of proper ventilation in hospital can affect bio-aerosol density in the hospital.
