Microbio Flashcards
It is the complete virus particles
Virions
Virions are observed using
Electron Microscope
These causes specific types of cancer
Oncovirus/oncogenic
Composed of many small proteins
Capsomeres
This is a protein coat composed of DNA or RNA
Capsid
Four categories of viruses based on the type of genomes they possess
Single-stranded DNA
Double-stranded DNA
Single-stranded RNA
Double-stranded RNA
This theory originated on the primordial soup
Coevolution theory
Evolved from free-living prokaryotes that invaded other living organisms
Retrogade evolution theory
Viruses are pieces of host cell RNA or DNA that have escaped from living cells and are no longer under cellular control
Escaped gene theory
Viruses that infect humans and animals
animal virus
attaches to a protein or polysaccharide molecule
attachment
the entire virus enters the host cell, in some cases it was phagocytosized by the cell.
penetration
the viral nucleic acid escapes from the capsid
uncoating
viral genes are expressed, resulting in production of pieces or parts of viruses.
Biosynthesis
the viral pieces or parts are assembled to create complete virions
Assembly
the complete virions escaped from the host cell by lysis or budding
Release
viruses that becomes enveloped escaped through
budding
Are remnants or collections
Inclusion bodies
hides from host’s immune system by entering and remaining dormant.
Latent virus infection
this is used to treat viral infection
antiviral agents
This virus causes Acquired immunodeficiency syndrome
Human Immunodeficiency virus
small infectious proteins that can cause neurologic diseases in animals.
prions
which cells does HIV attacks
CD4+ cells
what enzyme does retro viruses produce?
Reverse Transcriptase
this type of virus capable of inserting the viral genome into DNA
provirus
this virus is a crossover between bats to humans, this is also the biggest strands of virus.
Ebola virus
this virus is transmitted by mosquitos
zika virus
types of bacteriophages
virulent and temperate
this is prescribed in an attempt to prevent secondary bacterial infections.
Antibiotics
this type of bacteriophages causes lytic cycles
Virulent bacteriophages
this type of bacteriophages will remain into the bacterial cell chromosome, generation after generation.
Temperate bacteriophages
this type of virus can mimic a bacteria and can cause some cases of human pneumonia.
Mimivirus
this virus can interfere with the metabolism of plants.
viroids
what is the name of the shape of the bacteris that is round or spherical
cocci
what is the name of the shape of the bacteria that is rectangular or rod-shaped
bacilli
what are the three basic shapes of bacteria?
cocci, bacilli, curved and spiral-shaped
bacterias that exist in a variety of shapes are called?
pleomorphic
ability to exist in variety of shapes
pleomorphism
this fixation is accomplished by placing the slide on the slide warmer
heat fixation
this type of fixation is accomplished by flooding the smear with absolute methanol. This is also the standardized technique
methanol fixation
what are the 3 purposes of fixation?
kills the microorganisms, preserves the morphology, anchors the smear to the slide.
this type of stain is used to determine bacterial shape and morphologic arrangement.
simple stain
this type of stain is used to observes bacterial capsules, spores, and flagella
structural staining procedure
This procedure became the most important staining procedure in the bacteriology laboratory.
gram stain
