Pathophysiology chapter 14 (porth) Exam
Questions With Answers
Invasions of the human body by microorganisms that can produce harmful and potentially lethal
consequences.
What are infectious diseases?
Any organism capable of supporting the nutritional and physical growth requirements of another.
What is a host?
The presence and multiplication within another living organism.
What is infection?
The act of establishing a presence.
What is colonization?
Harmless bacterial to the internal & external exposed surfaces.
What is microflora?
Where the host is not adversely harmed because of the colonization of bacteria.
What is commensalism?
The host and invading bacteria benefit from the interaction.
What is mutualism?
One in which only the infection organism benefits from the relationship and the host either gains
nothing from the relationship or sustains injury from the interaction.
What is parasitic relationship?
Microorganisms that are extremely virulent and are commonly associated with disease.
What are pathogens?
The disease-producing potential of the microorganism. It is increases when the host is susceptible.
What is virulence?
Microorganisms that are capable of producing infectious disease when the health and immunity of
the host are compromised.
What are opportunistic pathogens?
Protein particles that are absent of any demonstrable genome.
What is a prion?
Prions, viruses, bacteria, Rickettsiaceae and Chlamydiaceae, fungi, and parasites.
What are agents of infectious disease?
, Creutzfeldt-Jakob disease.
What is a prion-associated disease in humans?
Various prion-associated diseases that produce very similar pathologic processes and symptoms in
the hosts.
What is transmissible neurodegenarative diseases?
A prion-associated disease.
A slowly progressive, noninflammatory neuronal degeneration, leading to loss of coordination,
dementia, and death over a period ranging from months to years can be called what?
By spreading within axons of nerve cells, causing progessively greater damage of host neurons and
the eventual incapacition of the host.
How does a prion-associated disease cause damage?
Virus.
What is the smallest obligate intracellular pathogen?
Herpesvirus, and paramyxoviruses (such as infulenza and poxviruses).
What are some enveloped virus members?
Covered with a protein coat and cannot replicate outside of a living cell. They may cause death during
replication.They may inject their genome in a host cell chromosome and lay dormant before causing a
disease.
Viruses are?
Herpesviruses, chickenpox, kaposi sarcoma, genital herpes, and cold sores.
What are some members of the latent virus?
Virus RNA is translated into DNA after entry into host through "reverse transcriptase". The translated
DNA is intergrated into host chromosome where it remains latent until reverse occurs.
How do retroviruses replicate?
A retrovirus.
HIV is what type of virus?
The infected cells regulate the immunologic defense system of the host and their lysis leads to a
permanent suppression of the immune response.
In a case of HIV what happens?
Viruses that have the ability to transform normal host cells into malignant cells during the replication
cycle. The group may includes retroviruses and DNA viruses.
What is oncogenic viruses?
