“…Sampling of air conditioner filters may identify hospital areas with excessive contamination with Aspergillus spp (eg, more than 50 CFU per sample) as defined by H e r m a n . 9 Further s u p p o r t for this application was obtained by showing that newly replaced filters in the highly contaminated utility room air conditioner became heavily recontaminated within one week of operation of the unit. Although the focus for A flavus recontamination of the utility room air conditioner has not yet been pinpointed, the filter sampling survey indicates a need for more intensive sampling in this area of the hospital.…”

Aspergillus flavus and Aspergillus fumigatus are important causes of invasive, often fatal, fungal disease in immuno-compromised patients. Sources of aspergilli for hospitalized patients may include window air conditioners, fireproofing materials, dust accumulated above false ceilings and acoustical ceiling tiles, and improperly functioning central ventilation systems. Renovation and construction projects, movement of heavy equipment, and demolition of nearby buildings often occur in or near hospitals. These events may aerosolize dust and soil laden with Aspergillus spores. Immunocompromised patients may acquire invasive aspergillosis in the hospital by inhalation of spores or by direct contact with contaminated intravenous arm boards. We have recently recognized the occurrence of invasive aspergillosis in an area of our hospital that does not contain false ceilings or a central ventilation system. All of the patient rooms in this area contain air conditioners that are attached to ceilings rather than windows, recirculating room air rather than drawing air in from the outside.

“…The diversity of free living micro-soil fungi has been well-established and known for a very long time (Srivastava and Mishra 1972;Alexander 1985;Ahmad 1988;Paul 2007;Imran 2009). Similarly, airborne microflora in hospital rooms were the subject of numerous studies as a potential cause of hospital infections (Herman 1980;Li and Hou;Arnow et al 1991;Pini et al 2004). In poorly ventilated buildings with damaged and poor air-conditioning systems, there may be an increase in the concentration of mycotoxicogenic molds, Penicillium and Aspergillus spp.…”
