Any organism capable of supporting the nutritional and physical growth requirements of
another is called a(n) _____. - Answer host
The term _____ describes the presence and growth of an organism within another living
organism that results in injury to the supporting organism. - Answer infection
_____ describes the act of establishing a presence, a step required in the multifaceted
process of infection. - Answer Colonization
The exposed surfaces of the human body are normally and harmlessly inhabited by a
multitude of bacteria, collectively referred to as the normal ______. - Answer microflora
A bacterial colonization that does not harm the host is a(n) _____ relationship. - Answer
commensal
The bacterial colonization of the gut results in a benefit for both humans and for the
bacteria. This type of relationship is known as _____. - Answer mutualism
_____ is the disease-producing potential of a microorganism. - Answer Virulence
Microorganisms that are nearly always found to cause disease are known as _____. -
Answer pathogens
_____ are microorganisms found everywhere in the environment and are nondisease
causing. - Answer Saprophytes
The study of factors that influence the transmission of infectious disease is known as
_____. - Answer Epidemiology
The number of new cases of a disease that occurs over a period of time is known as
_____ of disease. - Answer incidence
Abrasions, burns, medical procedures, or primary infectious processes are all potential
mechanisms of ______. - Answer penentration
_____ is the period of time where the pathogen is replicating but not causing any health
problems. - Answer Incubation
A(n) _____ is a localized pocket of infection composed of devitalized tissue,
microorganisms, and the host's phagocytic white blood cells - Answer abcess
Antibacterial medications are referred to as _____. - Answer antibiotics
, The disease producing potential of a microorganism - Answer Virulence
Preparation and growth of a microorganism outside the body for study or identification -
Answer Culture
Protein particles that lack any kind of a demonstrable genome - Answer Prion
Host and microorganism beneficial relationship - Answer Mutualism
Host defense substances that activate inflammation and immunity - Answer Cytokines
Microorganism that nearly always is associated with disease - Answer Pathogen
Collective group of all the organisms that inhabit the exposed surfaces of the body, but
cause no harm - Answer Parasite
Free-living organisms that obtain their needs for growth from dead and decaying
material - Answer Saprophyte
Microorganisms that are normally harmless and inhabit the internal and external
surfaces of the body - Answer Microflora
Organism that supports the growth of microorganisms - Answer Host
Which of the following best describes the structure of a virus?
a. Possesses both a cell wall and a cell membrane
b. Consists of a capsid that surrounds a nucleic acid core
c. Has a helical cell wall
d. A small prokaryote that lacks a cell wall - Answer Answer: b
RATIONALE: Viruses consist of a protein capsid that surrounds a nucleic acid core
(either RNA or DNA). Bacteria have both a cell wall and a cell membrane. Spirochetes
have a helical cell wall, and mycoplasma are bacteria that lack a cell wall.
The bacteria that line the gut of a human help maintain normal gut health and provide
essential nutrients. This type of relationship is
a. commensal
b. parasitic
c. saprophytic
d. mutualistic - Answer Answer: d
RATIONALE: The term mutualism is applied to an interaction in which the
microorganism and the host both derive benefits from the interaction. Commensalism is
a relationship where the organism receives benefit at no harm to the host. A parasite is
