INTRODUCTION
Our environment is blessed with the presence of inanimate and animate forms and both interact constantly. A good instance is the release of gases such as oxygen by plants into the atmosphere and consumption of the released oxygen by humans in other to produce carbon-dioxide. Carbon-dioxide and oxygen together with other gases combine to form air, the other substances that abound in air include microbial spores and vegetable cells that may be released through breathing, talking, wind action and aerosolization of water bodies, eventually we may breathe these particles in and these particles also become deposited on the inanimate surfaces around us (Obanya et al., 2018; Nazeri et al., 2019; Stephens et al., 2019).
Fungal contamination of air and inanimate surfaces has been a current topic under concepts such as communicable diseases or airborne diseases and fomite infections for the former. This explains why we contract a cough (29%), cold (25%), catarrh (65%) after encountering dust (32%), sharing a classroom with a sick person (44%) or operating Automated teller machines (28%), touching door knobs (23%). A laboratory houses indoor air and inanimate surfaces and presents the challenges mentioned already, especially in the absence of regular sterilization, sanitation and disinfection practices (Elawady and Tolba, 2009; Hazarin et al., 2015; Obanya et al., 2018; Nazeri et al., 2019; Stephens et al., 2019).
