Identification and Characterization of Bacteria Air Pathogens from Homes in Some Areas of the Baghdad City

To identify the different risks and to establish exposure thresholds, microbiology of air samples from a series of indoor environment should be characterized; and the different microorganisms must be identified and characterized. This research title, identification and characterization of bacteria air pathogens present in the air that could constitutes health risk to the inhabitants of these houses. A total of six bacterial pathogens were identified from the ten samples collected from ten zones, comprising of Staphylococcus spp., Bacillus spp., Escherichia coli, Salmonella spp., Shigella spp., and Pseudomonas spp. Staphylococcus spp., had the highest percentage of concern 95%, followed by Bacillus spp. 75%, Escherichia coli had 70%, while Pseudomonas had 50%, and the least was Sallmonella spp.and Shigella spp.had 30%, and 20%. Considering the fact that some of the isolated pathogenic bacteria are associated with gastrointestinal tract infection(Salmonella spp., Shigella spp., Escherichia coli, Bacillus spp., and Staphylococcus spp.) which could be through ingestion of food or water cotaminated by these pathogens and also respiratory tract infection(Pseudomonas spp.) constitute a great concern to health practitioners in developing countries because these are pathogens that are mostly resistant to the commonly avialable antibiotics used in the treatment of infection asociated with these pathogens.
