Assessment of Airborne Fungi in an Indoors Laboratory Toilet
Journal Title: IOSR Journal of Pharmacy and Biological Sciences (IOSR-JPBS) - Year 2016, Vol 11, Issue 3
Abstract
Fungi are ubiquitous in both indoors and outdoors environment, exposures to them result to allergies, infection and other adverse health conditions. The assessment of indoor fungi prevalent in six toilets (Biotechnology laboratory toilet 1 & 2, Microbiology laboratory toilet 1 & 2 and Applied Biology laboratory toilet 1 & 2) in Presco Campus, Ebonyi State University Abakaliki, was carried out in the month of November, 2015. Potato dextrose Agar was prepared and poured aseptically into Petri dishes, these were exposed in the toilets for five minutes and incubated for seventy two hours. Pure cultures of isolates were produced and identified, assessment of the hygienic conditions of the toilets was also carried out using questionnaires to elicit responses from those taking care of the toilets. The result revealed eight fungi species; Aspergillus, Trichosporonoides, Gibellula, Beauvaria, Stachybotrys, Illosporium, Botrytis and Rhizoctonia. Aspergillus spp were the most predominant in all the toilet with prevalent rate of 75 % , next to Aspergillus were Gibellula and Illosporium. Microbiology lab. toilet had only Aspergillus and also lowest fungi load. The lowest fungi load in Microbiology lab. toilets was related to frequent washing and moderate ventilation.
