Abstract:
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.
