“…The dominant fungi were Aspergillus spp, Penicilliums spp and Alternaria spp. Similar with often studies the mast prevalent fungus was Rhizopus, which was mostly dominant in dusty conditions (Jo and Seo, 2005, Sautour et al, 2009, Jensen and Schafer, 1998. This fungus is among the fungi which had the highest amount in dusty weather.…”

“…The average increase of fungi concentration before and after visiting was higher in comparison the other studies in Iran and other countries (Sautour et al, 2009, Azizyfar et al, 2009. In Iran, mean concentration of fungi in Kamkar hospital (Qom city) was 200 ±79.9 CFU/ m3 (Azizyfar et al, 2009).…”

“…In Iran, mean concentration of fungi in Kamkar hospital (Qom city) was 200 ±79.9 CFU/ m3 (Azizyfar et al, 2009). Sautour et al (2009) estimated low airborne fungi concentration ranging from 2 to 26 CFU/ m 3 in a French hospital. As the discussed hospital is aged and considered as educational hospital, the density of students, patients, nurses, visitors and hospital personnel develops an overcrowding.…”

“…Low quality of the air present in the hospitals directly influences the health of human especially in severe immune deficiency patients and those who are in prolonged contact (Sautour et al, 2007, Cordeiro et al). Main sources of infections in the hospitals are bacteria and fungi such as Aspergillus, Fusarium and Mucor which are rapidly increased recently and have caused the highest death tolls (Cordeiro et al, Wu et al, 2000, Rainer et al, 2001, Sarica et al, 2002, Sautour et al, 2009. Epidemiology of bioaerosols depends on: humidity, temperature, ventilation, organic particles available in constitutive materials, fungi load of outdoor and the quality of building (Sautour et al, 2009, Medrela-Kuder, 2003.…”

Prevalence of diseases originated from air pollution such as asthma and allergies, can be attributed to the bioaerosols. Bacteria and fungi are the main sources of hospital infections, which cause most of the diseases and mortality. The aim of this study was to determine the ratio of indoor to outdoor fungi concentration, the effect of population and people density on fungi concentration and the relationship between indoor and outdoor environment. In this study, three stations were used: outdoor of the hospital, general indoor and ICU wards of the Ahvaz hospital. These locations were chosen for sampling of the airborne fungi from October to December 2010. The samples were collected in 2 min, flow rate of 28.3 L/min using quick take (SKC Inc., PA, USA), based on the Andersen method.The three dominant culturable fungi genera in sampling stations were Aspergillus, Penicillium, and Cladosporium. The average of total culturable fungi concentration before visiting time was 365.8 CFU m -3 and increased to 578CFU m -3 after visiting time. The indoor to outdoor ratios (I/O) in ICU and internal for fungi before visit were 0.36 and 0.68, respectively. However, these ratios in ICU and internal station for fungi after visit were 0.78 and 0.99, respectively. Following the visit of the visitors, the concentration of fungi available indoor was conspicuously higher (even in the wards in which no visitors were allowed; e.g. ICU, etc). Hence the amount of indoor fungi was affected by the concentration of outdoor fungi and visitors crowd.

introduction:This study aimed to identify airborne fungi in São Luis, Maranhão, Brazil, to determine the prevalent genera and to correlate these genera with the area and season. Methods: In total, 1,510 colony-forming units (CFUs) of airborne fungi were isolated from the north, south, east and west sides and from the center of the city from January to December 2007. The samples were collected on Petri dishes that were exposed to the fungi by the gravitational method. Results: Twenty genera of fungi were isolated; the most common were Aspergillus (33.5%), Penicillium (18.8%), Cladosporium (14.2%), Curvularia (10.6%) and Fusarium (7.6%). The CFUs of the fungi were statistically signifi cant (p < 0.0001). Fungal biological diversity was present all year, without any large seasonal variations but with slight increases in May, August and September. Conclusions: The fungal genera identifi ed in this study were correlated with natural systems and could be useful when evaluating the impact of environmental changes on the region.
