Abstract

Samples from the buildings showing signs of deterioration like discolouration, cracking and peeling where collected and examined for the presence of both bacteria and fungi. Bacteria of varying gram reactions, shapes, and arrangements were isolated. They include gram positive cocci and positive rods. The isolates include Bacillus polymyxa, Bacillus alvei, Bacillus cereus, Bacillus coagulans, Bacillus firmus, Bacillus laterosporus, Staphylococcus epidermidis and Staphylococcus kloosii. Seven (7) species of fungi belonging to five (5) genera were isolated. They include Aspergillus niger, Aspergillus fumigatus, Mucor racemosus, Rhizopus stolinifer, Cephalosporium specie, and Penicillium specie. No, 32 Sultan Abubakar road has the highest bacterial count of 1.20 x 10 5 cfu and No. 7 Wurno road has the least bacterial count of 1.1 x 10 4 cfu. All the deteriorations were associated with two or more different species of fungi. Also most of the deteriorations caused by bacteria were found to be by more than one type of bacteria.
