Abstract
In the present scenario the poultry farms, chicken shops include the residues of feed, bedding, dust particles and bird’s feathers. Poultry farming is a very common small scale industry in towns, rural and urban residential areas. It is a significant source of microbial airborne contamination, which may play an important role in spreading microbial infections, exacerbate the breathing and respiratory problem in the workers that has drawn attention on public health issues in the society, study was conducted from January - April, 2025. Sampling of bioaerosol was performed by passive air sampling method (settle plate method), from ten different areas of Naini, Prayagraj, including major air pollutants and weather conditions viz., Temperature, humidity, AQI and average PM2.5, PM 10. NA and SDA plates were exposed in the indoor and outdoor areas for 15-30 minutes and plates were incubated at lab conditions for culture of bioaerosols. Viable microbial count was recorded and selected colonies were identified by gram’s staining, Lacto-phenol and biochemical methods. Incidence of bioaerosols were observed from indoor and outdoor environment i.e., minimum 4062.80 and 4849.15 (CFU/m3), maximum 7863.48 and 8125.60(CFU/m3) and fungi minimum 2568.74 and 2752.22 (CFU/m3) maximum 4508.40 and 4927.78(CFU/m3). Microbes were characterized i.e., Gram negative and gram positive bacteria, yeasts, molds and Keratinophilic fungi like., Bacillus species, Staphylococcus spp. Aspergillus niger, Aspergillus fumegatus, Aspergillus flavus, Aspergillus spp., Alternaria spp., Candida spp., Cladosporium spp.,Chysosporium spp., Mucor spp., Penicillium spp., maximum bioaerosols were recorded in summer as compared with winter season. Higher concentration bioaerosol release endotoxins and Mycotoxins during decomposing of keratinous, organic substances and long term exposure of airborne microbial cells and spores causes the skin infections, allergic infections, asthma, respiratory infections and adverse impact on animals and human health.
