This paper presents information about airborne microorganisms (bacteria and fungi) in the indoor air of two hospitals (Kashani and Hajar) in the city of Shahrekord, Iran. The settle plate technique using open Petri dishes containing different culture media was employed to collect a sample and using Quick Take 30 Sample Pump three days per week for a period of 8 weeks. Standard microbiological methods were employed for the identification of bacterial and fungal isolates. The results showed that the concentration of bacteria in the study area ranged from 0 to 70 cfu/plate/h, while the concentration of fungi was 0 to 280 cfu/plate/h. Also, 12 bacterial and 3 fungal species were isolated and identified with varying frequencies of occurrence, including spp. and , while the fungal genera isolated included Yeast, . While the bacterial isolates (20.50%) and (9.10%) were the most predominant airborne bacteria, yeast (22.70%) and (20.50%) were the most frequently isolated fungal species. The population of microorganisms was the highest during the afternoon. The statistical analysis showed a significant difference between the microbial loads of the two hospitals at < 0.05. The generated data underline the usefulness of monitoring the air quality of the indoor hospital.
本研究旨在介绍伊朗沙赫里萨德市卡沙尼和哈贾尔两家医院室内空气中空气传播微生物(细菌和真菌)的信息。研究采用沉降平板技术,使用开放式培养皿采集样本,每周采集 3 天,共采集 8 周。使用 Quick Take 30 采样器采集空气样本。采用标准微生物学方法对细菌和真菌分离株进行鉴定。结果表明,研究区域内细菌浓度范围为 0 至 70 cfu/平板/h,真菌浓度范围为 0 至 280 cfu/平板/h。共分离鉴定出 12 种细菌和 3 种真菌,其中 spp.和 最为常见,分离出的真菌属包括 Yeast 和 。细菌分离株中, (20.50%)和 (9.10%)最为常见,真菌分离株中,酵母(22.70%)和 (20.50%)最为常见。微生物数量在下午最高。统计分析显示,两所医院的微生物负荷存在显著差异(P<0.05)。这些数据强调了监测医院室内空气质量的重要性。
