AHU = Air Handling Unit Most Common Fungi: Aspergillus niger, Aureobasidium pullulans, Mucor plumbeus, Rhizopus stolonifer, Rhodotorula mucilagenous, Cladosporium, Penicillium spp, Trichoderma hazarianumm, Cunningham elegans, yeast. Most Common Bacteria: Bacillus spp, Gram negative rods, Gram positive cocci. Non-Viable Spores: Non-viable spore samples were taken from a wall cavity with a telephone jack: Penicillium/Aspergillus; Cladosporium and Stachybotrys chartarum. Q-PCR: ERMI tests: ERMI tests were performed on two samples. Identified fungi were: following: Acremonium strictum, Aspergillus fumigatus, penicillioides, niger, unguis, and ustus, Aureobasidium pullulans, Cladosporium herbarium, Eurotium amstelodami, Mucor/Rhizopus, Paecilomyces variotii, Penicillium chrysogenum, purpurogenum, spinulosum and variable, Rhizopus stolonifer and Wallemia sebi Wall Cavities: Wall check samples at two outlets (electrical and phone jack) collected by Air-0-Cell cassettes (14 L/min for 5 minutes) detected Aspergillus/ Penicillium at 95 and 87.5 % of the total spore counts of 390 and 1,600, respectively. Stachybotrys spores were detected in the phone jack outlet at 0.008 % if the total spore counts.
