Human-microbe interactions
1. Infectious disease: Disease caused by pathologic microorganisms such as parasites,
viruses, bacteria or fungi. Additionally, the disease can be spread either directly or
indirectly from one person to another. For example, Zoonotic diseases may be
infectiously transmitted to humans.
2. Infectious agent: refers to organisms such as pathogenic parasites, virus, and bacterium
capable of invading the body tissues, replicate itself and later causes disease. After
making contact, the infectious agent establishes as the focus of infection within the host.
3. Etiologic agent: refers to the causative agent of a disease condition, and in most case,
they are microbial toxins and microorganisms that cause disease in human. The etiologic
agent associated with development progressive of immunologic deterioration. The causal
agent includes bacterial toxins, viruses, and fungi.
4. Pathogen: the microorganisms that cause disease in a human by invading hosts and
immediate destruction of the immune systems. Pathogens comprise of organisms such as
bacteria, fungi, protozoa, and viruses. Medical points of view, pathogens are disease
producing agents such as virus and bacterium.
5. Non-pathogen: the organisms that are harmless to their host and may be beneficial to
their hosts. The staphylococcus epidermis forms part of the healthy skin flora,
lactobacillus acidophilus is part of the usual intestinal floral, and finally, Escherichia Coli
is part of normal flora found in the large and small intestine.

6. Commensal: refers to a relationship in which one organism obtains foods and other
benefits from another organism without harming or helping it. The bacterial species that
benefit from the association obtain nutrients, shelter, and support. For instance,
commensal bacterial forms part of the normal flora in the mouth.
