Other organisms that may be <br />suggestive of migration from the outdoors include Alternaria, Pitho!11yces, yeasts, and EpicOCCUl11 nigrU111, Fungal <br />organisms at elevated levels that are associated \vith fungal gro\vth on nloisture impacted building nlaterials <br />include Aspergillus, Penicilliul11, Chaet0l11iunl, AcrelllOlliulll and Triclzoderl11a. <br /> <br />C:\Documents and Settings\tallard\Local Settings\Temporary Internet Files\OLK.F\attach to 5 8.doc <br />
