Obligate pathogens require a host to fulfil their life cycle. All viruses are obligate pathogens as they are dependent on the cellular machinery of their host for their reproduction. Obligate pathogens are found among bacteria, including the agents of tuberculosis and syphilis, as well as protozoans...
Many of these respiratory infectious diseases are difficult to control or prevent, since they can spread quickly among people, through air as the medium. The airborne pathogens causing these diseases generally include bacteria, viruses and fungi. Till now, identification of these pathogens relies on ...
Aerosols are microscopic particles that can remain airborne for hours, and carry pathogens up to dozens of meters, under the right conditions. Scientists who study airborne infection generally consider aerosols to be particles smaller in diameter than five micrometers, or 0.005 millimeters...
