Abstract:

Molds, as filamentous fungi, may occur almost everywhere, even in water. They grow well in water that they can affect the health of the population or may have negative effects on food production. The aim of this study was carried out to determine the prevalence of molds in households’ drinking water. A total of 212 water samples were collected from 4 different Local Government areas of Kano Metropolis, out of which 3 were from boreholes, 135 from households, 36 from taps and 38 from wells. Mould species were isolated by using membrane filtration method with subsequent cultivation on agar plates. The different genera of moulds were identified using cultural and microscopic techniques. A total of 206 fungal colonies were isolated from water samples and cultivated for identification and the most frequently occurred genera were Aspergillus (36.4%), Penecillium (23.3%), fusarium (19.4%), and Bipolaris (5.8%). The mean value colony forming units for moulds 4.50, 3.60, 3.13 and 3.43cfu/100ml for borehole, household, tap and well respectively.

Keywords: Prevalence, Moulds, Drinking water, Household.
