Flashcards in Bacterial morphology And Ultrastructure Deck (19):
1

This uses cytoplasmic membrane that act as a mitochondria

Prokaryotic cell

2

What are the components of gram staining

Crystal violet
Mordant or gram's iodine
Acetone or ethyl alcohol
Safranin

3

The Mordant fixes the dye to what layer of the cell

Peptidoglycan layer

4

All cocci are gram positive except

Neisseria
Veillonela
Moraxella

5

All bacilli are gram negative except

Mycobacterium
Corynebacterium
Sporeformers bacillus

6

This is the outermost bacterial cell wall and also called a slime layer

Capsule

7

What is the main composition of the capsule

Polysaccharide Gel

8

Bacillus anthracis uses what kind of polypeptide

Poly D Glutamic Acid

9

What are the following capsulated microorganism

Streptococcus pneumoniae
Klebiesella pneumoniae
Haemophilus influenzae
Pseudomonas aeruginosa
Neisseria meningitidis
Cryptococcus neoformans

10

This is the essential component of a gram negative

Outer membrane

11

The part of the outer membrane that produces toxins specifically called endotoxin

Lipid A

12

This layer is found in all living bacteria except in mycoplasma

Cell wall
Peptidoglycan layer

13

Two sugars found in the peptidoglycan layer

NAM
NAG

14

What does the gram positive cell uses to attach itself to the host cell

Teichoic acid
Lipoteichoic acid

15

What kind of lipid layer does the acid fast bacteria contain

Mycolic acid

16

What does the gram positive bacteria use to store large molecular enzyme since they don't have periplasmic space

Exoenzyme

17

Spheroplasts and protoplasts are seen where

Spheroplasts - + outer membrane seen in gram neg

Protoplasts - - outer membrane seen in gram pos

18

Difference between pili and flagella

Pili - straight

Flagella - curly

19

What region of the bacteria contains the genetic material

Nucleiod region
Nuclear body
Chromatin body
Nucleic region
