Bacteria kingdom
Monera
A bacterial cell is a
Prokaryote
Mycology kingdom
Fungi
What is peptioglycan?
The macromolecule that makes up the bacterial cell wall (proteins and sugars)
What is contained by all gram + cell walls
Teichoic acid
Why are fungal infections hard to treat
Because fungi share common cell structures as human cells
How does teichoic acid work
Protrudes above cell walls creating a negative charge. the positive charge will
allow for a stronger bond with the stain that is negatively charged.
In the glycoalyx, genes are
Transferable
, 2
What type of cell is fungus
Eukaryote
Antimycotics
Although there is no treatment for a viral infection, to stop it the virus must.....
Be killed prior to entering a cell or the host cell must be killed prior to releasing
replicated viruses
Kingdom Protista
Protozoa
Kingdom animalia
Helminths
Two phylum of helminths
Phylum: nemahelminths
Phylum: platyhelminths
What are the contents of a bacterial cell wall
Repeating units of sugars held together by peptide chains called peptidoglycans
What is a glycocalyx
capsule or slime layer of a bacterial cell that inhibits phagocytosis
What is associated with dental decay due to the loose adherence of the surface
Glycocalyx slime layer
What is a fimbraie
The sticky projections on a bacterial cell used for adherence, found on gram stain
organisms
What is pili
A bacterial conjugation
What has mobility through twitching
Pili
, 3
Pili is involved in the development of
Biofilms
What are flagella used for
Motility
What is the pattern of bacterium locomotion
Run, tumble, tumble, run
Axial filaments are called
Endoflagella
How to endoflagella rotate
Corkscrew; can bore through tissue
What are Plasmids "DNA Donuts"
Extra chromosomal pieces of DNA that carry genes for toxins and antibiotic
resistance.
How are plasmids transferred
Via pili during conjugation
Endoscopes or internal spores are in response to
Environmental stress
What is the only bacterial structure that is soil dwelling gram + rods
Endospore
Endospores have an extreme resistance to
Heat, desiccation, toxic chemicals, UV radiation and antibiotics
Spore formers
Clostridium tetani
Clostridium botulinum
Bacillus antracis
What are the physical requirements for bacterial growth
