Key words:
Outdoor, airborne, bacteriological pollution; antibiotics sensitivity; ecological tests. 
The Earth’s atmosphere is teeming with airborne micro-organisms. Most outdoor airborne bacteria are known to be originating from natural sources such as soil, animals, and men. These organisms are thought to exhibit correlation with air pollution and weather. Several early investigations were undertaken to determine the relationship between the number of viable bacteria found in the air and various meteorological parameters, such as temperature, humidity, and wind speed. Several morphological, biochemical, physiological, and ecological tests were carried out. Nearly 100% of our strains were catalase positive, a great proportion of the strains were Gram positive, according to the tolerance tests were varied, the coccide strains were more tolerant to different salt concentration, opposed to rods exhibiting better tolerance to temperature. Sensitivity tests were carried out by the diffusion method using Mueller–Hinton medium (1941). Specific antibiotics were chosen. Varying sensitivity values were obtained; however, the highest degree of sensitivity could be detected in case of Gentamycine and Vancomycin whereas the highest values of resistance were detected with Pefloxacine.
