"Aero-Bacteriology of Occupation Associated Environment"

M icroorganisms are ubiquitous in nature; they inhabit soil, water, plant, and animals and sustain their lives on variety of available energy sources. When the growth conditions of these microorganisms in reservoir are favourable, they amplified and disseminated from their habitats to other places. The release of these microorganisms from these reservoirs is either active (self) or passive (environmental factors) in nature. Aerosols formed when the particles of dusts, sprays, mists, smokes and fumes dispersed in gas. When, these organisms as a whole or its parts dispersed in air, known as a primary biological aerosol particles or bioaerosols. The organisms in bioaerosols may be saprophyte, opportunistic or primary pathogens in nature; comprises the agents such as viruses, bacteria, actinomycetes, fungal spores, algae, plant cells, insects, mites, and their fragments, endotoxin from Gram-negative bacteria, mycotoxins and glucans from fungi.
