Discuss how a pathogen causes an infection. Include definitions for primary pathogen, opportunistic pathogen, infection, disease (caused by a living organism), and various stages of pathogenesis. You can choose a specific organism to describe

Infections are generated by pathogens, pathogens that generate a rare invasion triggering an extremely risky condition for the host, opportunistic infections are usually caused by highly pathogenic microorganisms with high resistance mechanisms and are really serious signs and symptoms.

Primary pathogen is one that colonizes in a primary way by forming a biofilm or a microbiological ecosystem.

The great difference between infection and infectious disease is that the infection is the presence of microorganisms that cooperate and live with the host without generating pathology, whereas infectious disease is when these microorganisms generate a pathology or condition in the host.

Explanation:

The pathogenesis are different stages that make up the ability of a microorganism to get sick, an example is prevotella parvula or treponema denticola that during pathogenesis they quickly invade the tissues due to their movements, in addition to the tissues such as the mucosa they generate an immune distraction that release toxins in different areas to the invasion.

These are pathogenicity mechanisms, that is, how the microorganism does to be able to invade the tissues in the most oppressive way.

well schools are being forced to embrace computers. unlike their "digital immigrant" teachers, these students are "digital natives", born into a world where technology is an integral part of everyday life. almost every student has access to a multitude of computers, laptops and tablet devices. it would be crazy to assume an assignment would  not be written on computer in this day and age.

sandy loam should be dominated by the sand. as the amount of sand increased, the amount of slit needed to anchor the plants' roots to the sand will also be increased. even though the amount is very little, 10% part of clay is still necessary for proper oxidation.
