Microbiological Assessment of Soil from Dump Sites Near Male and Female Hall of Residence in Bayero University Kano Old Campus

This study investigated the microbiological assessment of two dumpsites in Bayero University Kano (old site). Dumpsites are a prime source of environmental pollution that constitutes a habitat for vector and other nuisance organisms capable of transmitting or causing diseases. The aim of the research is to isolate and identify the microorganisms present in soil from various dumpsites close to male and female hall of residence in BUK old site. A total of 4 soil samples was collected on different locations from each site labelled A-D. The isolates that were obtained were identified and characterized using staining techniques and biochemical tests. The total bacterial count for S1 ranged from 1.7 x 10⁹ cfu/g to 3.9 x10⁹ cfu/g while the count for S2 ranged from 1.8x10⁹ cfu/g to 5.2x10⁹ cfu/g. The total fungal count for S1 ranged from 2.0x10⁹ CFU/g to 3.9 x10⁹ CFU/g while the count for S2 ranged from 1.7x10⁹ CFU/g to 5.2x10⁹CFU/g. Four gram negative bacterial isolates (Klebsiella, Proteus, Salmonella, and Pseudomonas) and four isolates positive (Bacillus spp, Staphylococc aureus, Staphylococcus spp, and Streptococcus spp) to Gram staining were obtained. A total of five fungal isolates (Aspergillus fumigatus, A. flavus, A. niger, Rhizopus spp, and Basidobolus ranarum) were obtained. From these experimental results, it was shown that pathogenic microorganisms were discovered to be present in soil samples from various dumpsites.
