Study Notes
Identifying Bacteria
- Bergey's Manual of Determinative Bacteriology provides identification schemes for bacteria and archaea based on morphology, differential staining, and biochemical tests.
- Bergey's Manual of Systematic Bacteriology provides phylogenetic information on bacteria and archaea based on rRNA sequencing.
Laboratory Identification
- Morphological characteristics are useful for identifying eukaryotes.
- Numerical and rapid identification methods are used.
- Differential staining techniques include Gram staining and acid-fast staining.
- Biochemical tests determine the presence of bacterial enzymes.
Serology
- Involves reactions of microorganisms with specific antibodies.
- Useful for identifying strains and species, and determining relationships among organisms.
- Techniques include slide agglutination, ELISA, and Western blot.
Phage Typing
- Involves determining the susceptibility of bacterial species and strains to various phages.
Genetics
- DNA fingerprinting: uses restriction enzymes to produce DNA fragments (fingerprints) to determine genetic similarities.
- Ribotyping: uses rRNA sequencing to identify organisms.
- Polymerase chain reaction (PCR) amplifies small amounts of microbial DNA in a sample.
Nucleic Acid Hybridization
- Involves the bonding of single-stranded DNA or RNA from related organisms to form a double-stranded molecule.
- Applications include Southern blotting, DNA chips, and Fluorescent In Situ Hybridization (FISH).
Taxonomy
- The Three-Domain System: Eubacteria, Archaea, and Eukarya.
- Endosymbiotic Theory: explains the origin of eukaryotes.
Scientific Nomenclature
- Common names vary with language and geography.
- Binomial Nomenclature (genus + specific epithet) is used worldwide and is a universal standard.
- Examples of scientific names include Escherichia coli and Homo sapiens.
