Antibiotic Resistance Mechanisms
Antibiotic resistance mechanisms enable bacteria to survive antimicrobial treatment through enzymatic degradation, target modification, efflux pumps, and reduced permeability.
Bacterial Cell Wall Structure
The bacterial cell wall provides structural integrity and determines Gram classification through its peptidoglycan composition.
Bacterial Genetics
Bacterial genetics studies the structure, function, and transfer of genetic material in bacteria, including mutation and horizontal gene transfer.
Bacterial Pathogenesis and Virulence Factors
Bacterial pathogenesis describes how bacteria cause disease through virulence factors that enable colonization, evasion, and tissue damage.
Gram Staining Technique
Gram staining is a differential staining technique that classifies bacteria as Gram-positive or Gram-negative based on cell wall composition.
Quorum Sensing in Bacteria
Quorum sensing is a cell-to-cell communication mechanism by which bacteria regulate gene expression collectively in response to population density.
