Bacterial classification methods and characteristics

CLASSIFICATION SYSTEM

1. PHENETIC CLASSIFICATION

   • METHOD
     • Numerical taxonomy
       • Computer assisted taxonomy
     • Simple matching coeeficient

2. PHYLOGENETIC CLASSIFICATION

   • METHOD
     • Sequencing 16sRNA or 18sRNA
     • International databases genebank
     • Ribosomal Database Project
     • Phylogenetic tree

3. GENOTYPIC CLASSIFICATION

   • METHOD
     • CLASSIC CHARACTERISTICS
       • Morphologicaly characteristics
       • Physiological and metabolic characteristics
       • Biochemical characteristics
       • Ecological characteristics
     • MOLECULAR CHARACTERISTICS
       • Comparison of proteins/ amino acids sequences
       • Nucleic acid base composition
       • Nucleic acid hybridization
       • Genomic fingerprinting
