Bacterial morphology And Ultrastructure Flashcards
This uses cytoplasmic membrane that act as a mitochondria
Prokaryotic cell
What are the components of gram staining
Crystal violet
Mordant or gram’s iodine
Acetone or ethyl alcohol
Safranin
The Mordant fixes the dye to what layer of the cell
Peptidoglycan layer
All cocci are gram positive except
Neisseria
Veillonela
Moraxella
All bacilli are gram negative except
Mycobacterium
Corynebacterium
Sporeformers bacillus
This is the outermost bacterial cell wall and also called a slime layer
Capsule
What is the main composition of the capsule
Polysaccharide Gel
Bacillus anthracis uses what kind of polypeptide
Poly D Glutamic Acid
What are the following capsulated microorganism
Streptococcus pneumoniae Klebiesella pneumoniae Haemophilus influenzae Pseudomonas aeruginosa Neisseria meningitidis Cryptococcus neoformans
This is the essential component of a gram negative
Outer membrane
The part of the outer membrane that produces toxins specifically called endotoxin
Lipid A
This layer is found in all living bacteria except in mycoplasma
Cell wall
Peptidoglycan layer
Two sugars found in the peptidoglycan layer
NAM
NAG
What does the gram positive cell uses to attach itself to the host cell
Teichoic acid
Lipoteichoic acid
What kind of lipid layer does the acid fast bacteria contain
Mycolic acid
