General Biology Flashcards
Prokaryotes (Prenucleus)
Single cellular except Cyanobacteria
Prokaryotes Domain 1
Bacteria (Environmental cyanobacteria/blue-green algae and Medically relevant bacteria)
Prokaryotes Domain 2
Archaea (Extreme habitats: high salt conc, jet fuel, high temperature)
Prokaryotes Characteristics
Circular chromosome, Cell wall with peptidoglycan
Eukaryotes (True nucleus)
Fungi and Parasites; Single or Multicellular organisms
Eukaryotes Characteristics
Linear chromosome, Cell wall with NO peptidoglycan
Infectious Particles
Viruses - Host-dependent infectious agents
Infectious Particles
Prions – Abnormal infectious proteins
TAXA
Domain – Kingdom – Phylum – Class – Order – Family – Genus – Species
Microbial Nomenclature
Binomial system; Latin/Greek-derived; Italicized or Underlined
Genus
First letter in UPPERCASE
Species
First letter in lowercase
Classification, nomenclature, and identification of organisms
Taxonomy
Variations in gene expression not caused by nucleic acid sequence similarities or differences
Epigenetics
Organizing microorganisms into groups based on similar traits
Classification
Methods providing microbiologists with relevant clinical information about a microorganism
Identification
Naming microorganisms according to ICNP rules
Nomenclature
Same species with same genetic make-up but with differential physiologic characteristics
Biotype/Biovar
A strain differentiated based on antigen types using specific antibodies
Serotype/Serovar
Specific version or subtype of an organism with minor differences
Strain
Characterization of etiologic agents using molecular techniques during an outbreak
Strain Typing/Sequencing
Macroscopic and microscopic morphology, staining characteristics, environmental & nutritional requirements, resistance profiles, antigenic & subcellular properties, chemotaxonomic properties
Phenotypic
DNA base composition ratio, nucleic acid base sequence, average nucleotide identity (ANI), genome-to-genome distance
Genotypic
Ability of a microorganism to produce disease in a host
Pathogenicity
