    • Structure of bacterial cell
    • Cell wall Gram(+) cell wall Gram(-) cell wall thick peptidoglycane  thin peptidoglycane  no teichoic acids teichoic acid, lipoteichoic acid  outer membrane - .molecular screen.  integral proteins polysaccharides  Porins  permeases,  translocation proteins  protein receptors  lipopolysaccharide LPS = endotoxin (negative charge, hydrophobic, anti-phagocytotic, toxic)  lipid A  core polysaccharides  O-antigen
    • Gram stain method
    • Cell wall:Peptidoglycane or murein network-like polymere surrounds the cell like net bag many layers very rigid Gram(+): lysozyme may break protoplast Gram(-): penicillin may break spheroplast L-form
    • Flagella-for motilitylong spiral protein chains-flagellin
    • Position Of flagella
    • Pili- for attachment;- for changing ofDNA betweenbacteria (sex ofbacteria).
