Presentation Transcript


  1. Bacterial Genetics

  2. Heredity and variation • heredity • variation genotype variation phenotype variation

  3. Variation • morphology and structure • virulence • resistance • colony 光滑型菌落(smooth,S) 粗糙型菌落(rough,R)

  4. genetic materials • chromosome • plasmid • bacteriophage,phage • transposon,Tn

  5. Classification of plasmid • 根据细菌的接合作用 (conjugative ,nonconjugative) • 根据质粒的不相容性 (incompatibility) • 根据编码的生物学性状 (fertility,resistance,virulence)

  6. 质粒的诱动(mobilization)

  7. Bacteriophage

  8. Life cycle

  9. transposon

  10. mechanism of bacterial variation • mutation • gene transfer and recombination

  11. mutation • spontaneous mutation • wild strain • wild type • mutant strain • mutation types • reverse mutation) • suppressor mutation)

  12. Transfer and recombination of gene • transformation • conjugation • transduction • generalized • Restricted • lysogenic conversion • protoplast fusion

  13. Application • Diagnosis,prevention and treatment • Detection of tumor • Epidimiology • Molecular biology • Engineering
