WHAT IS MICROBIOLOGY?
REFERS TO ANY WHOLE ORGANISIM WHICH IS NOT VISIBLE TO ANKED EYE
ARE ORGANISIMS LIVING OR NON LIVING
BOTH
WHERE ARE MICRO-ORGANISIMS?
UBIQUITOS
EVERYWHERE
WHAT ARE THE FUNCTIONS OF MICRO ORGANISIMS?
DECOMPOSITION - ANTIBIOTIC PRODUCTION - FOOD PRODUCTION - GENETIC ENGINEERING
WHAT ARE THE CATEGORIES OF MICROBES?
ACCELULAR - CELLULAR
WHAT ARE ACELLULAR MICROBES?
INFECTIOUS PARTICLES WHICH NEED TO ENTER A CELL HOST - ARE NOT ALIVE - CAN NOT REPRODUCE
WHAT ARE THE TYPES OF ACELLULAR MICROBES?
VIRODS - VIRUSES - PRISONS
WHAR ARE VIRODS?
INFECTIOUS PARTICLES CONSISTING OF SHORT PIECES OR RNA THAT INTERFERES WITH PLANT CELLS
WHAT ARE PRIONS?
INFECTIOUS PARTICLES CONSISTING OF SMALL PROTEINS THAT CAUSE NEUROLOGICAL CONDITIONS IN HUMANS AND ANIMALS
WHAT ARE VIRUSES?
A SECTION OF DNA OR RNA WITH. PROTEIN COAT
WHAT CAN VIRUSES INFECT?
ALL TYPES OF ORGANISIMS
WHAT ARE CELLULAR MICROBES?
LIVING MICROBES
WHAT ARE THE TYPES OF CELLULAR MICROBES?
PROKARYOTES - EUKARYOTES
WHAT ARE PROKARYOTES?
BACTERIA - ARCHAEA
WHAT ARE EUKARYOTES?
ALGAE - FUNGI - YEAST - PROTOZA
WHAT IS A GRAM STAIN?
TEST USED TO STAIN BACTERIA T DETERMINE ITS TYPE
WHAT IS GRAM POSITIVE?
THICK LAYER OF PEPTIDOGLYCAN ON OUTSIDE SURFACE OF CELL THAT STAINS PURPLE
WHAT IS GRAM NEGATIVE?
THIN LAYER OF PEPTIDOGLYCAN SANDWICHED BETWEEN LAYERS OF COMPLEX MOLECULES - NO STAIN
HOW DO BACTERIUM BUILD A RESITATNCE?
BY EXCHANGING PLASMINDS RESULTING IN MULTI DRUG RESISTANT STRAINS OF BACTERIUM
DO SOME BACTERIA PRODUCE ENDOSPORES?
YES
WHAT ARE ENDOSPORES?
THICK WALLED STRUCTURES THAT CONTAIN A COPY OF THE CHROMOSONE CYTOPLASAM
WHAT DO ENDOSPORES DO?
ALLOW BACTERIA TO TO SURVIVE IN ADVERSE ENVIRONMENTS
HOW DO ENDOSPORES WORK?
WHEN THEY LAND IN A SUITABLE ENVIRONMENT THEY GERMINATE TO PRODUCE NEW BACTERIUM
WHAT IS ALGAE?
PHOTOSYNTHETIC EUKARYOTIC ORGANISIMS
WHAT IS FUNGI?
A DIVERSE GROUP OF EUKARYOTIC ORGANISIMS
WHAT IS FUNGI INCLUSIVE OF?
YEAST - MOULD - MUSHROOMS
WHAT DOES FUNGI DO?
BREAKS DOWN ORGANIC MATTER
WHAT ARE THE TWO TYPES OF FUNGI?
PARASYTIC AND SAPHROPHYTIC
WHERE DOES PARASITIC FUNGI LIVE?
HUMANS, ANIMALS, PLANTS
WHERE DOES SAPHROPHYTIC FUNGI LIVE?
WATER AND SOIL
WHAT IS YEAST?
SINGLE CELLED EUKARYOTIC ORGANISIMS
WHERE IS YEST FOUND?
WATER, SOIL, SKIN OF VEGETABLES & FRUIT
WHAT IS PROTOZA?
GROUPS OF UNICELL EUKARYOTIC MICROBES THAT ARE DIVIDED BY MOVEMENT
WHERE IS PROTOZA FOUND?
SOIL AND WATER
WHAT TYPS OF PROTOZA ARE THERE?
AMOEBAE - CILIATES - FLAGELLATES - NON-MITOLE PROTOZA
HOW DO AMOEBAE MOVE?
MOVE BY EXTENDING A PORTION OF THE MEMBRANE
HOW DO CILIATES MOVE?
BY USING THE CILIA ON THE OUTSIDE OF THE CELL SURFACE
HOW DO FLAGELLATES MOVE?
BY USING A FLAGELLA (TAIL)
HOW DO NON-MOTILE PROTOZA MOVE?
NON MOBILE PROTOZA
WHAT IS MICROFLORA?
A COMMUNITY OF MICROBES THAT LIVE ON OR IN ANOTHER ORGANISIM
WHERE DO MICROFLORA LIVE?
IN OR ON THE HUMAN BODY
WHAT ARE PATHOGENS?
MICROBES THAT CAUSE DISEASE - ABOUT 3% OF MICROBES ARE PATHOGENIC
WHAT ARE NON PATHOGENS?
MICROBES THAT DO NOT CAUSE DISEASE
WHAT IS AN OPPORTUNISTIC PATHOGEN?
MICROBES THAT ARE USUALLY HARMLESS BUT MAY CAUSE DISEASE IF THEYC OLONISE INT HE WRONG BODY PART
WHAT IS AN INFECTIOUS DISEASE?
PATHOGENS SPREAD DIRECTLY FROM ONE PERSON TO ANOTHER
