Abstract
Background & Objectives: Pools and Saunas are one of the most public areas that may cause superficial and cutaneous mycoses in humans. So investigating the fungal flora in the mineral swimming pools like Sarein area can remove or reduce the contamination or prevent the probablity of fungal infection. Methods: A total of 284 samples from 11 mineral swimming pools were taken of which 214 were from pools, sauna Jacuzzis, tubs and showers which were covered by sterile moquette and 70 were from water in saunas, jacuzzis, tubs and showers which were collected in sterile test tubes. All of the samples were cultured in standard method on sabouraud dextrose agar (SDA), sabouraud dextrose agar+oleic acid (S+O) and sabouraud dextrose agar+ chloramphenichol+cyclohexamide (SCC) medias, then identified macroscopically (colony morphology )and microscopically. Results: From 284 samples, 193 were contaminated with fungi. The most frequently isolated species in 11 pools were Aspergillus fumigatus (22/79%), Aspergillus flavus (15/54%), Aspergillus niger (15/54%) and Penicillium (14/5%) respectively. On the other hand, Ulocladium, Sepedonium, Acremonium, Pscilomyces, Stemphylium and Streptomyces with 0.51 % were the least frequently isolated species. In this study, no dermatophytes or other true dimorphic pathogenic fungi were isolated from samples. Conclusion: So it can be concluded that routine hygiene inspections such as disinfection of pools, personnel training and following hygienic rules were much effective in lowering the comtamination. Also mineral waters of these pools can be growth inhibitors of pathogenic and dermatophytic fungi.

Abstract
Background & objectives: The purpose of this study was to determine the bacterial bioaerosols in indoor air of Ardabil universities and to investigate the factors affecting their concentration in Ardabil city.
Methods: Air sampling was performed using Andersen single-stage sampler at a flow rate of 28.3 liters per minute and a respiratory range of 10 min. In this study, trypticase soy agar containing cycloheximide antibiotic was used for bacterial culture. Biochemical tests such as DNase, catalase, oxidase, coagulase, bile esculin hydrolysis test, urease, citrate test, antibiotic resistance to novobiocin, bacitracin and optochin were used for identification and differentiation of isolates.
Result: The mean bacterial concentration in Ardabil university of medical sciences in the open air, outside the college, the halls, the classrooms and the staff rooms was 18, 88.4, 76.6, 77.4 CFU/m3 , respectively. The concentration of bacteria in Islamic Azad university of Ardabil in the open air, outside the college, the halls, the classrooms and the staff rooms was 103, 97, 124, 132 CFU/m3, respectively. The dominant species of bacteria in indoor air were Staphylococcus aureus, Staphylococcus epidermidis, Actinomycetes and Bacillus, respectively.
Conclusion: According to the results of this study, it is found that the concentration of bacterial bioaerosols in indoor air is not more than standard, but the abundance of bacterial species can cause lung, intestinal and other diseases in academic personnel, staff and students in the long-term.
