Pathogenicity
Infection and Transmission
The infections are generated by the pathogenic organisms present in the environment. They maintain the capacity to invade a host body and establish colonies. A disease caused by such infectious agents is called a communicable disease or transmissible disease. These diseases spread through diverse means including blood, food, water, air, or vectors.
Microbial recognition and tissue damage initiate an inflammatory response. True/False: The inflammatory response is characterized by four classic symptoms: heat, redness, pain, and swelling. In some instances, this response can be triggered by stimuli that are non-infectious such as asbestos, a process known as ‘sterile inflammation.’ When exposure to the stimulating trigger is persistent, a state of chronic inflammation can result. This process is likely to be detrimental to the health of the host.
