UNIT 1 Taxonomy Flashcards
organism population that is differentiated from populations
within species
Strains
Father of Taxonomy
CAROLUS LINNAEUS
Uses the separation and analysis of high abundance peptides for the classification and identification of bacterial isolates
MALDI-TOF-MS
Subspecies types:
- Strains
- Biovars
- Serovars
Family name Suffix
–aceae
Hierarchical Classification:
- DOMAIN
- KINGDOM
- DIVISION or Phylum
- CLASS
- ORDER
- FAMILY
- TRIBE
- GENUS
- SPECIES (EPITHET)
- SUBSPECIES
The most basic taxonomic group
SPECIES (EPITHET)
variation in serological reactions; strains with distinctive antigenic properties
Serovars
Binomial classification
CAROLUS LINNAEUS
CARL WOESE (1971) Basis of Classification:
■ Cellular Organization
■ Function
Order name Suffix
–ales
principles for defining natural genera and
species of organisms, known as
“Binomial
Nomenclature” or Binomial classification
MALDI-TOF MS
Matrix-Assisted Laser Desorption Ionization Time-Of-Flight ass Spectrometry
CARL WOESE (1971) Divided the organisms into 3 Domain System:
■ Bacteria
■ Eukaria
■ Archaea (ancient bacteria)
variant prokaryotic strains characterized by biochemical or
physiological differences
Biovars
Proposed the 5 Kingdom Taxonomic System
ROBERT WHITTAKER (1969)
Nomenclature is limited to two taxa:
genus and species
polyphasic taxonomy is Based on similarities and differences in the ff.:
- GENOTYPIC (GENETIC MAKE-UP) CHARACTERISTICS
- PHENOTYPIC CHARACTERISTICS
- PHYLOGENETIC (Evolutionary Relationships)
3 distinct but interrelated disciplines of taxonomy
- classification
- nomenclature
- Identidication of organisms (ID)
As a result of the advances in Molecular Biology, classic
taxonomy has now become what is referred to as
polyphasic
taxonomy
ancient bacteria or organisms that live in extreme environments such as deep-sea hydrothermal vents, hot springs, the dead sea, acid lakes and salt evaporation ponds
Archaea
ROBERT WHITTAKER (1969) Basis of Classification:
○ Cellular Organism
○ Nutritional Pattern
Tribe Names Suffix
-eae
The type strains of organisms are deposited in reference type culture collections such as
American Type Culture Collection
(ATCC) and National Type Culture Collection (NTCC)
