Nasal swab cultures of seventy adults who are proximal residents of the abandoned city dumpsite were collected in order to determine the colonizing microflora of their anterior nares. Nasal bacterial colonization rates of microorganisms were greater during wet season, which might be due to proliferation of microorganisms from fecal matter that were left behind when there is a hard rain wash. Conventional methods were employed for the morphological (growth patterns in nutrient agar plate, slant and nutrient broth) and cellular (Gram stain, simple sporulation stain and acid-fast stain) characterization of the 214 bacterial strains that were isolated for their preliminary classification. Physiological characterization was done through catalase and coagulase tests, blood agar hemolysis, mannitol salt and glucose fermentation reactions. The presumptively identified bacterial strains were Staphylococcus aureus (79), coagulase negative staphylococci (17), Streptococci (17), Corynebacterium (32), Bacillus (24), Micrococcus luteus (14), Mycobacterium (4) and Lactobacillus (27).
