Study Notes
Basic Classification of Bacteria
- Bacteria classification is primarily based on shape, arrangement, and staining characteristics.
Grape-like Aggregates
- Bacteria that are grape-like and stick together, forming aggregates, are referred to as staphylococci.
Rod-shaped Bacteria
- Rod-shaped bacteria that can produce endospores are called bacilli.
Combined Shape Bacteria
- Bacteria that have a combined appearance of both cocci and bacilli due to their shorter and longer sizes are known as coccobacilli.
Curved Rod-shape Bacteria
- Curved rod-shaped bacteria, resembling bacilli but having a bent structure, are termed vibrio.
Short Spiral Bacteria
- Bacteria that are spiral in form but shorter with less pronounced coils are referred to as spirilla.
Staphylo- Classification
- The prefix "staphylo-" indicates that the bacteria grow in clusters or grape-like formations.
Strepto- Nomenclature
- The prefix "strepto-" signifies that bacteria are arranged in chains.
Diplo- Naming
- The prefix "diplo-" indicates that bacteria exist in pairs.
Quartets of Bacteria
- Bacteria that form aggregates of four during binary fission are known as tetrads.
