LESSON 2: Nomenclature and classification of microorganisms Flashcards
is exclusively a population of a single kind of
microorganism in an environment regardless of number.
Pure culture
The descendants of pure culture
are called
Strains
A collection of strains having similar characteristics are called
Species
collection of species having similar characteristics are called
Genus
A group of
similar genera (genus)
Family
A group of similar families is
Order
A group of similar order
Class
A group of similar classes is
Division
A group of similar division
kingdom
are the one responsible in naming and classifying organisms based
on its stability and predictability.
Toxonomists
Meaning, new information about an organism would only
create minor changes in its classification, and similar characteristics among group.
One of the common and most reliable methods of classifying microbes is by genetic
relatedness between organisms based on their hereditary material
Currently the organisms are classified into three domains:
Eubacteria
Archaea
Eukarya
is consisting of bacteria with cell walls containing peptidoglycan.
Eubacteria
previously under eubacteria, are prokaryotes that lack peptidoglycan in their cell walls).
Archaea
a includes protists (protozoa, algae), fungi (yeasts, molds, mushrooms), plants, and animals
Eukrya
In 1735 the Swedish botanist ( —– )
developed a simple nomenclature
system to classify and name all organisms referred to as binomial nomenclature
Carl linnaeeus
Linnaeus developed a simple nomenclature
system to classify and name all organisms referred to as
Binomial Nomenclatures
Each organism is assigned two Latinized named
First name is called the genus.
The second name is the specific epithet, which is the name of the species
Scientific name of an organism can also be derived from its description, a researcher
or its habitat.
Fields of study Microoganism
: Study of bacteria.
Study of fungi.
Mycology
Study of protozoans (animal like single celled eukaryotic organisms).
Protozoology
Study of viruses and viral diseases. Although viruses are non-cellular in
nature, they are included in microbiology due to
(1) the techniques used to study
viruses are microbiological in nature, and
(2) the diagnostic procedures used are
employed in microbiological laboratories.
Virology
Study of parasitism and parasites (include pathogenic protozoa, helminthes worms
Parasitology
Deals with the immune system that protects against infection and to
study serology reactions.
Immunology
