Bacterial Morphology Flashcards
Causes general infections
- Streptococci
Causes local infections
- Staphylococci
Grows in pairs and is round
- Diplococci
Causes bacterial pneumonia
- Diplococci
Grows in bunches or clusters like GRAPES
- Staphylococci or Staph
Borrelia burgdorferi which causes lyme disease
- Spirilla
Causes puss
- Staphylococci and Streptococci
Branching filamentous bacteria
- Actinomycetes
Rod-shaped organisms
- Bacilli
Causes diseases such as syphilis (Treponema pallida)
- Spirilla
Round shaped and appear in groups/singularly
- cocci
Irregular shapes
- Pleomorphic
Causes diseases such as influenza, tetanus and tuberculosis
- Bacilli
Grows in chains and is round
- Streptococci
Corkscrew, or spiral shaped organisms
- Spirilla
“railroad track” branching filaments
- dermatophilus
Mycoplasma
- pleomorphic
Contains a thick layer of peptidoglycan and Teichoic Acid
- Gram positive bacteria
Contains an outer membrane, a thin layer of peptidoglycan and endotoxins (LPS - lipopolysaccharide)
- Gram negative bacteria
E. coli and Pseudomonas
- gram negative rods
Clostridium
- gram positive rods
Mycobacterium
- acid fast bacteria
Clostridium and Bacillus
- form spores
Do gram positive or gram negative bacteria form spores?
- gram-negative bacteria DO NOT form spores
Mycoplasma and Ureaplasma
- have NO cell walls
- > triple layered outer membrane
