Exam (50) Questions
Like bacteria in cytoplasm etc
-
How was it transmitted
-
Evidence of hemolysin toxin
-
20 or 30 will be rated to cases
-
Then the 20 questions will be related to general stuff like difference btw prokaryotes and
eukaryotes
-
One on the bear which will have 10 questions
Smaller than and simpler than host
-
Pathogens(Pathos)
Small seed
-
Simpler and smaller than any other animal
-
These are the bacteria
-
Genetic material in cytoplasm
○
It means that the shape of a bacteria is only limited to a few (spiral, circular, rod
shaped)
▪
Rigid Cell walls
○
Targets cell walls directly or cell wall synthesis
▪
Antibiotics - Penicillin
○
Controls the flow of ions and solutes inside the cell to maintain homeostasis
▪
Determines which solutes and ions move in and out
▪
Determines what drugs move in and out
▪
Inside the bacteria is a cytoplasmic membrane
○
Sliminess helps to prevent phagocytosis
□
Polypeptides, polysaccharides ---> slimy
▪
Bacteria with capsules tend to be more pathogenic
▪
Some bacteria have capsules
○
Long hair like strands
▪
Without it then it cannot
□
Allows the bacteria to attach to substrates… to infect
▪
Pilli (important structure in pathogenesis)
○
To move
▪
Bacteria with flagella tend to be more pathogenic
▪
Flagella
○
Structure
-
Genetic material attaches to the cytoplasmic membrane -->. Breaks into two to
get to smaller ones
▪
Binary Fission (NO MEIOSIS OR MITOSIS)
○
F+ donating to F- through a sex pillus
▪
Transferring genetic material to another bacteria
▪
Conjugation
○
Bacteriophage injects material into host
▪
Lyse host to release from host
▪
Picks up extraneous DNA from virus itself
▪
This is the most common way for antibiotic resistance to be transferred
▪
Transduction (More important)
○
Reproduction
-
Prokaryotes
