Taxonomy Flashcards
Refers to the classification and grouping of organisms. Is based on genotypic (genetic) and phenotypic (observable) similarities and differences.
Taxonomy
Provides naming assignments for each organism
Nomenclature
how does Binomial System work
Genus name + Species Name
eg. Staphylococcus aureus
(species name is not capitalized)
1st Standard Rule of Bacterial Names
Family name is capitalized and ends with - “aceae”
2nd Standard Rule of Bacterial Names
-Genus name first letter should be capitalized
-Species name is all in lower case
-Both genus and species should be: Italicized in Print or Underlined if script (handwritten)
3rd Standard Rule of Bacterial Names
To abbreviate genus names you can use capitalized first letter of Genus name followed by a period then add species
eg. Staphylococcus aureus = S. aureus
4th Standard Rule of Bacterial Names
Genus name can followed by the word “species” may be used to refer to genus as a whole
eg. Staphylococcus species
5th Standard Rule of Bacterial Names
To abbreviate species you can use sp (singular) or spp (plural)
eg. Staphylococcus sp or Staphylococcus spp
6th Standard Rule of Bacterial Names
bacteria are referred to as a group are neither capitalized nor underlined
eg. staphylococci
7th Standard Rule of Bacterial Names
plural of genusis is genera
eg. There are many genera in the Enterobacteriaceae family.
literally means “living together
Symbiosis
Involve protection or other advantages to one or both partners
Symbiosis
means “eating on the same table”
Commensalism
association that is beneficial to one partner and at least not advantageous to the other
Commensalism
a type of commensalism where association are beneficial to both organisms
Mutualism
a symbiotic relationship in which the host is injured through the activities of the other
Parasitism
two Pathogenecity
Non-pathogenic
Pathogenic
What is Non-pathogenic
Normal Flora
Bacteria present in the body which does not cause a disease
What is Pathogenic
Bacteria which can cause a disease
What are the Metabolic Characteristics
Obligate aerobes
Obligate anaerobes
Facultative anaerobes
Microaerophilic bacteria (aerotolerant anaerobes)
it requires oxygen for growth
Obligate aerobes
are killed by O2 ; grow maximally at O2 concentration less than 0.5% to 3%
Obligate anaerobes
grow in the presence or absence of oxygen
Facultative anaerobes
is the most pathogenic bacteria
Facultative anaerobes
