which is part of the normal flora colonizing the human skin, nose, and other body parts. Most of the time, it will bring no harm but can become infectious or cause disease when it gains entry through an open wound. Conversely, the termfrank (true) pathogenspertains to infectious agents th...
Introduction Although bacteria represent the majority of the human microbiota, fungi can also successfully colonize our bodies, either as pathogens or commensals. To understand how these uninvited guests impact human health and disease, it is critical to catalog fungal species associated with the human...
The opportunistic disease occurs mainly due to the suppression of host resistance, which, in turn, is due to the disruption or the absence of the components of the immune system of the host. Opportunistic pathogens are usually present in healthcare settings as hospitals. Such pathogens cause oppo...

Many bacteria exist in relatively benign associations with their hosts, such as the Escherichia coli bacteria in the human large intestine. Some resident bacteria can become pathogenic under certain circumstances. These opportunistic pathogens can cause serious infection in hosts whose defenses are ...
As obligate intracellular pathogens, Rickettsia bacteria cannot survive outside the body of a host. For this reason, they cannot be found living freely in terrestrial or aquatic environments. However, they can be found in different types of vectors (arthropods) including mites, lice, fleas, and ...
The human body employs three lines of defense against pathogens: mechanical and chemical barriers, the innate immunesystem, and the adaptive immune system. The first line includes skin and mucous membranes that block pathogen entry. The innate immune system features phagocytic cells, such as macrophag...
The human body, for instance, has bodily organs made up of cells functioning in unison. These organs, although distinct from one another, have to work alongside each other in order to sustain a set of internal conditions within the ideal range. There are various homeostatic processes and each...
No cases of naturally occurring smallpox have been reported since. (Smallpox, 2023) Animal reservoirs Animal reservoirs may vary — from the invertebrates such as ticks, mosquitoes, and other arthropods, to vertebrates, such as mammals, birds, reptiles, etc. Many human pathogens are classified ...
