Aeromycological Inventory of Indoor Air of Specialist Hospital Idah, Kogi State, Nigeria

Abstract

Aeromycological inventory of indoor air was carried out over the Specialist Hospital Idah
within the sampling period of August, 2022. The abundance and distribution of fungal aero
pathogens suspended in the atmosphere were investigated. Prepared plates of Potato Dextrose
Agar (PDA) were taken to Specialist Hospital Idah and were exposed to five (5) wards to take
fungal sample of indoor air of the wards for 15 minute and the plates were taken back to the
laboratory for incubation and monitoring of fungal growth. Fungal genera isolated were
Mammaria echinobutryiodes (3%), Cladorrhinum foelundisimum (4%), Oidiodendron
echinulatun (4%), Idriella lunata (4%), Ryparobius polysporous (6%), Rhizopus sp. (16%),
Celphalosporium acremonium (7%), Aspergillus niger (21%), Cladosporium sp. (30%),
Mucor sp. (34%) and Penicillium notatum (41%). Penicillium notatum was identified to have
the highest frequency (41%). The proportion of fungi in indoor air at Specialist Hospital Idah is
not the same within the periods of investigation. Improvement of general hygiene and
sanitation system is encouraged in order to reduce the spread of aero-microbes.
