Spirochetes
Syphilis
Vibrios
coma
Actinomycetes
resemble fungi
Mycoplasmas
No stable morphology
Arranged in bunches like grapes
Staphylococci
Arranged in pairs
Pneumococci
Arranged in chains
Streptococci
Site of action of some antibiotics
Cell wall of bacteria
One of the most common methods
used in microbiology lab to quickly
identify bacteria
Gram stain
- Some disinfectants & antibiotics act at this level
Cytoplasmic membrane
Production of Energy & Synthesis of cell wall components
Cytoplasmic membrane -
Functions
has antibiotic resistance functions
Plasmids
Acts as antigen
Capsule
Pilus Made up of protein called
PILIN
Found in gram negative bacteria.
Sex pili
Spores Killed by
Autoclaving (1210c for 15 mins)
Sporing genera are
Clostridium & Bacillus
single flagellum at one pole
monotrichous
tuft flagellum at one pole
Lophotrichous
amphitrichous
flagella at both poles
peritrichous
flagella all over
Amphilophotrichous
tuft of flagella at both ends
less permeability so more resistance in
gram-negative cell
more lipid
gram-negative cell
more peptidoglycan
gram-positive cell
proteins present in
gram-negative cell
outer membrane present in
gram-negative cell
