Microbes
[prokaryotes ]
- present of nucleoid
- peptidoglycan cell wall
- absence of mitochondria and other organelles except for ribosomes
- asexual reproduction (binary fission)
structure
- capsule
- cell wall
- plasma membrane
- cytoplasm
- ribosome
- nucleoid
- pilus
- fimbrae
- flagellum (locomotion)
- plasmid
pilus: transfer dna from one cell to another (conjugation)
fimbrae: stiff fibers that adhere to surfaces such as host cells
flagellum: in charge in locomotion of the cell
plasmid: carries antibiotic resistance genes
capsule: allows them to sticky to surfaces nd prevent phagocytosis of wbc
-
-
eukaryotes
- membrane bound nucleus
- cell wall (cellulose for plant cell)
3.presence of other organelles
- sexual reproduction
-
protozoa (eukoryotes)
- unicellular
- contains a nucleus bound membrane
- motile via flagellum
- free-living/parasitic ( infest from living host cell)
eg: malaria
- gametes-malaria parasitic enters bloodstream and enters RBC
- ruptured RBC and released gametes malaria parasitic due to hemolysis
Amoeba:
- due to poor sanitary
- ingested infected cyst in the small intestine
- trophozoite enters the colon and grows
- invade liver & lungs
symtopms:
GI tract infection
Fungi (eukaryotes)
microscopic: yeast, hyphae
macroscopic:
mushroom, gill fungi
fungal infection:
deep / superficial
-
Endospores:
= sleeping mode
capable of high resistance and long term survival
To eradicate:
presurised steam at 120degrees celcius for 20-30mins
bacteriophages:
- small size bacteria
2.do not affect the human body
- used alone or w antibiotics to treat bacteria infections
