The human nasal microbiota plays an important role in the health of the hosts including the proper functioning of the immune system, nutrition and resistance to infections. This study was conducted to gain knowledge on the nasal microbiota of healthy children who are constantly exposed to open dumps. Nasal swab cultures were taken from 124 healthy asymptomatic children with mean age of 7.7 years, who were living near open dumpsites. There was an average of 142 colony forming units per swab (CFU/swab) from all nasal swab culture plates. The isolated bacterial strains were characterized by colonial, cellular and morphological properties and were subjected to series of biochemical tests. These are the presumptively identified isolates from the nasal swab cultures, in which some are potentially pathogenic: Staphylococcus aureus (69), Mycobacterium sp. (37), Corynebacterium sp. (26), Lactobacillus sp. (22), Bacillus sp. (21), coagulase negative staphylococci (7), E. coli (1) and G- non E. coli (3).
