Tcdha, Microbiology Practice Questions with
Verified Correct Answers
what is microbiology?
study of small like forms ex.
viruses, bacteria, fungi (molds, yeasts)
protozoa
algae
archaea
what are several sub-disciplines in microbiology?
1. bacteriology (study of bacteria
2. mycology (study of fungi)
3. protozoology
4. virology
immunology
knowledge of body defense mechanisms (immune system), adds to understanding of disease
prevention through immunization and natural barriers of the body against infection.
what is infection control?
understanding of physical and chemical properties of microorganisms,
- where they exist
- grow
- how environment, physical and chemical agents influence them
-how they cause disease
,(prevention of microbial contamination and infection, and spread from person to person)
girolamo fracastoro
- recognized existence of tiny living particles that cause "catching" (contagious) diseases
-spread by direct contact with humans, indirect contact with objects
- known for naming syphilis in poem
antoni van leeuwenhoek
- discovered bacteria
- first to see a microbe
Developed a primitive microscope
- Named these small forms of life "animacules"
- wrote to the royal society about his observations on the plaque between his own teeth
edward jenner
credited with concept of immunization
louis pasteur
- known as father of immunology
- associated living organisms with disease
- found out using heat destroys bacteria that is vegetative and resistant bacterial spores
- discovered bacteria produced diseases (anthrax and cholera)
- created first vaccines for rabies, anthrax and cholera
john tyndall
, - discovered need for prolonged heating to destroy bacteria
- discovered bacteria existed in two forms heat-sensitive and heat-stable
- discovered tyndallization which is the prolonged heating or intermittent to destroy heat-
stable/heat-sensitive bacteria
ferdinand cohn
- discovered endospores which is the dormant form of bacteria with enhanced resistance to
heat, staining, and disinfection
joseph lister
- discovered role of airborne microorganisms
- discovered that airborne microorganisms can be reduced with carbolic acid which is now
known as phenols
- he used phenols in world war 2 surgeries to clean wounds
- using phenol to boil instruments and wash hands and surgical linens before surgery reduced
complications
christian gram
- discovered gram staining
- gram staining has 2 dies, purple/blue and safranin (red)
- gram staining divides the bacterial world into two groups; gram positive and gram negative
- gram staining determines differences in the cell wall
- gram positive and gram negative can be distinguished by
their colour they turn when stained with crystal violet dye
and cell wall structure which affects how they respond to antibiotics and severity of
infections they cause
