“…It was found that in terms of fungi, the greatest number of detected fungi was related to the Aspergillus genus (34). A study of Awosika et al revealed that the maximum of the study of fungal and bacteria concentrations were Aspergillus, Penicillium and Staphylococcus, respectively (35). Due to their ability for growth and proliferation in any place and development of thin and permeable spores into the depth of alveolus and growth at 37°C, Aspergillus species are observed frequently (36).…”

Background: Bio-aerosols in the air of hospital wards have an important role in the development of infections. It is important to make quantitative and qualitative estimations of microorganisms in the air of these wards as an index for environmental hygiene applicable to different hospital wards. The aim of the study was to investigate degrees of diversity and density of bio-aerosols in the education hospitals of Kerman city. Methods: This study applied a descriptive-cross-sectional methodology in the second half of 2014 in the education hospitals of Kerman city, with bed capacity of over 300. As many as 200 samples were collected from the air in different wards of each hospital using the standard method of the National Occupational Health and Safety Institute. Following collection, samples were placed in an incubator for 48 hours and then bio-aerosol detections were made for and resulting data reported as colonies/m 3 . Results:Results indicated that maximum and minimum degrees of bacterial density were observed in operation rooms and in the intensive care unit (ICU) of Shafa hospital. Furthermore, comparison showed that the operating room at Afzalipour hospital had the lowest level of fungal contamination, while ICU at Bahonar hospital had the highest level of fungal contamination. The emitted fungi of Aspergillus and Penicillium along with the bacteria, staphylococci and Acinetobacter had greater frequencies. The means of bacterial density and fungal density were not equal across the studied hospitals and significant statistical, difference was observed between means of bacterial and fungal density (P ≤ 0.001). Conclusion: Amounts of bacterial and fungal density were greater than those proposed in the American Industrial Health State Conference in 73.3% of the wards in the educational hospitals of Kerman city sampled in this study. Therefore it is suggested that implementation of some, necessary measures for continuous monitoring, promotion of hygienic disinfection standards, and ventilation systems are taken more seriously by stipulating regulations to control this important issue in the country's hospitals.

“…Awosika, in his study, reported that the most common fungi found in hospital wards were Aspergillus flavus, Penicillium, Fusarium, Candida albicans, and Alternaria (17). Despite the fact that the current study was conducted in a different geographical area, fungal diversity was almost similar to Awosika (32,33).…”

“…A similar study carried out in Poland (Fraczek and Gorny, 2011), also noted a range of 21 -6223. All these reports however differed from some reports from the rest of Nigeria, which noted low microbial loads with ranges such as 42 -100, 422 -1386 and 45 -1125 CFU/m 3 (Makut et al, 2014;Ambrose et al, 2015;Awosika et al, 2012). One common observation of the various studies, was the effect of human activity on microbial load.…”
