Study Notes
Bacterial Morphology
- Diplococci are characterized by pairs of cells.
Streptobacilli
- Streptobacilli have a characteristic arrangement of chains of cells.
Staphylococci
- Staphylococci are represented by grape-like clusters.
Cell Structure
- The outer membrane serves as the primary permeability barrier in gram-negative bacteria.
Prokaryotic Nucleus
- There is no true nucleus in prokaryotic cells, and the genetic material is found in a single circular chromosome.
Clostridium tetani
- Spores are located in the central region of the cell in Clostridium tetani.
Polyphosphate Granules
- Polyphosphate granules serve as energy and phosphate reserves in bacteria.
Plasmids
- Plasmids are small, self-replicating circular DNA molecules that can provide antibiotic resistance and other beneficial traits to bacterial cells.
Fimbriae
- Common pili/Fimbriae are hair-like appendages that aid in bacterial adhesion and biofilm formation.
Flagella
- Periplasmic flagella are typically found in spirochetes.
- Lophotrichous flagella are a type of flagella that have a tuft of flagella at one or both poles of the organism.
Cytosol
- The cytosol is the jelly-like substance inside the cell membrane where metabolic reactions take place in bacteria.
