摘要：Upper respiratory diseases are one of the most frequent health damages associated with air pollution. It is also known that they are the main causes of laboral and school absentism. Therefore, a comparative bacteriological study was done among two populations, exposed to high and low levels of air polution todetermine afterwards if there are any alterations of the oropharynx normal bacteria. An important number of Gram negative strains was observed, among two groups of urban population (adult and young), especially those of the Enterobacteriaceae and Branhamella catarrhalis . These results were statistically significant when adult populations from urban and suburban populations were compared (P<0.05). Streptococcus faecalis was most easily isolated from infants from the urban zone. One of the most potentially dangerous pathogens isolated among the oropharynx indigenous bacteria was Staphylococcus aureus , it was also frequently found among the urban habitants. These results suggest that the patogenicity of Enterobacteriaceae in the oropharinx should be revised. Suggestive data of fecal contamination in the oropharyngeal flora of the people of the high polluted ara are presented. Sanitary actions should be improved besides of the effort in trying to reduce the air pollution.
