Viruses and Prions/ Bacteria Flashcards
'
Gram negative is a bacterium with a
Thin cell wall that has a internal membrane
A pathogen that cannot survive outside the host cell is a
Obligate intracellular parasite
An aerobic organism that can switch to anaerobic respiration when necessary is known as a
Facultative anaerobe
The bacterial cell wall is made of
Peptidoglycan
A phage that kills the host cell after one round of viral replication is known as a
Lytic
Bacteriophage DNA that became integrated into the host cell chromosome
Prophage
Adherence to the intestinal lining by a bacterium may be due to its possession of
Pili
Archaea have a
Ether linkage
Bacteria have a
Ester linkage
Active immunization is considered as
Indivduals making their own ANTIBODIES
Passive immunization is known as
Artifical (like breast milk)
Active immunization stimulates a persons
IMMUNE SYSTEM (antibodies and memory cells)
Prions replicare by
Converting normally-folded versions of proteins into MISFOLDED VERSIONS
Some groups of bacteria can go dormant during periods of environmental stress through the formation of
Endospores
3 main domains are
Bacteria, Archea, and Eurkarya
