LESSON 1-5 INTRODUCTION Flashcards
Tthe study of small life, and small life refers to microorganism or microbes.
MICROBIOLOGY
microorganism exist as :
- CELLULAR MICROBES- bactera, fungi, archea, protists
- ACELLULAR MICROBES- need host cells, virus,viroids
Microorganism can be:
- PATHOGENIC- can infect and cause disease to human, animals, & plants
- NON-PATHOGENIC- microorganism that are beneficial to the host
-population of microorganism naturally present within a healthy body:
NORMAL MICRO FLORA
Cell shape, size, structure, cell arrangement. staining reaction, motility, flagellar movements
MORPHOLOGIC BACTERIA
-chemical constotuents of cell,
CHEMICAL COMPOSITION
-nutritional requirements & physical conditions required for growth.
CULTURAL CHARACTERISTICS
-how cells obtain and use their energy, carry out chemical
reactions, and regulate these reaction
METABOLIC REACTIONS
-distinctive chemical components (antigens) of the
microorganism.
ANTIGENIC CHARACTERISTICS
-hereditary material of the cell
GENETIC CHARACTERISTICS
-abilitiy to cause a disease of microorganism
PATHOGENECITY
-habitat and distribution of microorganism in nature, and
interactions between and among species in natural enveronment
ECOLOGICAL CHARACTERISTCS
-although not strictly microorganisms, these organisms
are microscopic in some stages of their development
MULTICELLULAR ANIMAL PARASITE
this type of microorganism are also called, prokaryotes. (no nuclear membrane)
BACTERIA
-lthis type of microorganism are prokaryotic cell, and it’s cell wall lack peptidoglycan.
ARACHAEA
-this type of microorganism are eukaryotic cell, can be unicellular or multicelluar
FUNGI
-unicellular eukaryotic; move by appendage
PROTOZOA
-photosynthetic eukaryotes; cell walls are made of cellulose (plant carbohydrate).
ALGAE
-acellular microorganism; made either of DNA or RNA surrounded by a protein
coat, that is sometimes further encased in a lipid membrane; need host cells to
reproduce
VIRUS
7 Types of microorganism:
BACTERIA
ARACHAEA
FUNGI
ALGAE
PROTOZOA
VIRUS
MULTICELLULAR ANIMAL PARASITE
-the descendants of pure culture are?
STRAINS
-a collection of strains having similar characteristics are called?
SPECIES
-a group of similar class are called ?
DIVISION
-a group of similar division is?
KINGDOM
organisms are classified into 3 domains:
- EUBACTERA- bacteria w/ cell walls containing peptidoglycan
- ARACHAEA- under eubacteria
- EUKARYA- (protozoa, algae, yeast, mold, mushrooms)
-are the one responsible for naming & classifying organism based on it’s stability and predictability.
TAXONOMIST
Swedish botanist, developed simple nomenclature. ?
CARL LINNAEUS
-in thisn system, each organisms os assigned 2 latinized the name. ( genes & specific epith. )
BINOMIAL NOMENCLATURE
This organism was name from the scientis Theodore Escherich w/ specific epithelial coli means:
“ORGANISM LIVES IN COLON OR LARGE INTESTINES”
Escherichia coli.
it means, “clustered coccus”
Staphylo
Auereus for?
golden
-is the ability of a pathogenic microbe to
develop a resistance to the effects of an antimicrobial medication.
ANTIMICROBIAL RESISTANCE
