WGU Microbiology D311 Section 2 - Study Guide
Questions With Solutions
Bacterial habitats Right Ans - Water, soil, food, host
(plants,animals,humans), waste
Microbiome Right Ans - All of the microbes (bacteria, viruses, and so on)
with all of their genes in a community; here, the millions of microbes of the
human body.
extremophiles Right Ans - live in extreme environments
Thermophiles Right Ans - Archaea that thrive in very hot environments
Psychrophiles Right Ans - cold-loving microbes
Rhizosphere Right Ans - the soil layer that surrounds actively growing
roots
microbial ecology Right Ans - the study of microorganisms in their natural
environments
Community Right Ans - A group of interdependent organisms inhabiting
the same region and interacting with each other
Symbiosis Right Ans - An ecological relationship between organisms of two
different species that live together in direct and intimate contact.
Mutualism Right Ans - a relationship where both organisms benefit
Commensalism Right Ans - a relationship between two organisms in which
one organism benefits whilst the other (host) is neither harmed or benefited
Parasitism Right Ans - a relationship between two organisms in which one
species benefits while the other is harmed (host)
resident microbiota Right Ans - species of microbes that are always
present on or in another organism
, transient microbiota Right Ans - temporarily found in the human body, and
these may include pathogenic microorganisms.
infectious disease Right Ans - a disease caused by a pathogen
communicable disease Right Ans - a disease that is easily spread directly or
indirectly from one person to another
contagious disease Right Ans - easily spread from person to person
iatrogenic disease Right Ans - disease caused by or acquired during a
medical procedure
nosocomial disease Right Ans - disease acquired in a hospital setting
zoonotic disease Right Ans - any disease that is transmitted to humans by
animals
noncommunicable disease Right Ans - a disease that is not transmitted
from one host to another
noninfectious disease Right Ans - not caused by a pathogen; disease caused
by something other than an infectious agent (e.g., genetics, environment, and
nutritional deficiencies)
portal of exit Right Ans - anatomical feature of the body through which
pathogens can leave diseased individual
vector Right Ans - animal (typically an arthropod) that transmits a
pathogen from one host to another host; DNA molecules that carry DNA
fragments from one organism to another
mechanical vector Right Ans - an animal that transfers a pathogen from
one host to another or from a reservoir to a host without being infected by the
pathogen itself
