    (Sage Publications Ltd, 2002) Sarica, S; Asan, A; Otkun, MT; Ture, M
    The aim of this investigation was to monitor monthly the densities and distribution of indoor airborne fungi and bacteria in 6 different areas of Trakya University Hospital (Edirne, Turkey). Areas monitored were an operating theatre, birthing-room, emergency department, service area for infectious diseases, intensive care unit and the canteen. Our method was to expose Petri dishes which contained rose-bengal streptomycin agar and 5% sheep-blood agar media to room air for 10-min periods. Samples were collected at 1-month intervals from September 2000 to February 2001. A total of 156 microfungal and 535 bacterial colonies were counted on 144 plates. During a 6-month period, 10 bacterial genera (Acinetobacter, Bacillus, Corynebacterium, Enterococcus, Escherichia, Listeria, Micrococcus, Propionibacteria, Staphylococcus and Streptococcus)7 fungal genera (Altemaria, Aspergillus, Cladosporium, Paecilomyces, Penicillium, Scopulariopsis and Trichothecium) and 33 fungal species were isolated from the hospital air. Penicillium loliense, P. melinii and P. phoeniceum were newly recognised species for Turkey. Some bacterial species such as coagulase-negative Staphylococcus, Micrococcus and Corynebacterium spp. were predominant (percentages of colonies counted were 72.2, 10.7 and 8.8%, respectively). Cladosporium and Penicillium were the most prevalent fungal genera. Cladosporium was predominant in September, November and February, Alternaria in October and December and Penicillium in January. Staphylococcus spp. was the most common bacterial species in all months. Statistical analyses (regression with optimal scaling test) were applied to the data.

    Monitoring of fungi and bacteria in the indoor air of primary schools in Edirne city, Turkey
    (Sage Publications Ltd, 2005) Aydogdu, H; Asan, A; Otkun, MT; Ture, M
    We monitored levels of bacteria and fungi in the indoor air at selected sites of several public primary schools in the city of Edirne, Turkey. Sampling was by the Petri plate method onto both a Rose-Bengal streptomycin agar medium and a 5% sheep-blood agar medium exposed to the air for 10-minute periods. Samples were collected monthly over a period of 6 months between August 2001 and January 2002. A total of 941 microfungi and 2066 bacterial colonies were counted on 90 Petri plates. During this 6-month period, 19 bacterial genera, 15 fungal genera and 48 species of fungi were isolated from the air in the schools. Some bacteria, such as coagulase-negative Staphylococcus, Corynebacterium and Bacillus, were predominant (42.7%, 20.4% and 6.9% of the total, respectively). Penicillium, Cladosporium and Alternaria were the most common fungal genera (42.8%, 19.3% and 10.1% of the total, respectively). Staphylococcus, Acinetobacter, Corynebacterium, Propionibacterium and Pseudo-monas genera were found in every month. Statistical analysis of the data showed a positive correlation between the concentrations of bacteria and air humidity (p = 0.002, R-2 = 0.726) and between bacterial concentrations and age of the schools (p=0.045, R-2 = 0.787). Also, that there was seasonal variation since the concentrations of fungi and bacteria varied according to the months (p = 0.001).
