Swartkoppie Cherts
What is concerned with the relationship of organisms with their environment?
Microbial Ecology
Who developed a vaccine for various diseases via attenuation techniques?
Louis Pasteur
Microbes produced energy and carbon via photosynthesis to areas with absence to light -
Microbial Ecology
Neutrophils elevate during bacterial infection -
Immunology
Diagnosis and treatment to protect and prevent infectious diseases caused by pathogenic microbes
Public Health Microbiology
Microbial solutions enable farmers ways to protect their crops from pests and diseases
Agricultural Microbiology
Microbes can be used to create high-value products such as drugs, chemicals and fuel -
Industrial Microbiology
Which of the following is NOT an importance of bacteria?
A. Not found anywhere in the planet
B. Causes disease in animals and plants
C. Contribute to the oxygen supply since some are able to photosynthesize
A. Not found anywhere in the planet
Who designed to prevent microorganisms from entering wounds by developing a system of surgery?
Joseph Lister
Who performed the Swan neck-flask experiment?
Louis Pasteur
Who is considered the Father of Microbiology and the Father of Microscopy?
Antonie Van Leeuwenhoek
What is concerned with the control and spread of communicable disease?
Public Health Microbiology
Who discredited Spontaneous generation / segregation?
Francisco Redi
What are the earliest molecules?
RNA
Which of the following is NOT an acellular microorganism?
Protists
What is the root or origin of modern life as a bacterial branch of controversial nature?
Last Universal Common Ancestor
Who established the relationship between Bacillus anthracis and anthrax?
Robert Koch
Who discovered the bacteria-engulfing phagocytic cells in the blood?
Ellie Metchnikoff
Which is NOT a Koch’s Postulate?
A. The suspected microorganisms must be isolate and grown in pure culture
B. The particular bacteria cannot be grown in pure culture in the Laboratory
C. The same microorganisms must be isolated again from the diseases host
The particular bacteria cannot be grown in pure culture in the Laboratory
Differentiate Prokaryotes and Eukaryotes
Refer to your module packets/notes
Can produce their own cell wall
Cellular
Do not produce their own cell wall
Acellular
Depends on their host to grow
Virus
Cannot live without another virus
Satellite Virus
Composed of Proteins but causes diseases to animals and humans
Prions
Explain John Needham Experiment
His experiments;
Mutton broth - boiled - sealed
Results: broth became cloudy and contained microorganisms
Idea that living organisms can develop from non- living or decomposing matter
Spontaneous generation
Showed that if dust was absent, nutrient broths
remained sterile, even if directly exposed to air and provided evidence for the existence of
exceptionally heat-resistant forms of bacteria
John Tyndall
Heat-resistant bacteria could produce
endospores
Ferdinand Cohn
____are like eggs containing DNA that enables germination of the said bacteria again in favorable conditions
Endospores
Demonstrated that the great Potato Blight of
Ireland was caused by a water mold
M.J Berkeley
Showed that a disease of silkworms was
caused by a fungus
Agostino Bassi
Showed that smut and rust fungi caused cereal crop diseases
Heinrich de Bary
Father of Hand washing
Joseph Lister
immunity obtained from other organisms (e.g. antibodies obtained from mother’s breast milk)
Passive Immunity
immune response created by our own body
Active Immunity
Studies soil microorganism and discovered
numerous interesting metabolic properties
(e.g., nitrogen fixation)
and they Pioneered the use of enrichment cultures
and selective media
Sergei Winogradsky and Martinus
Beijerinck
Infectious agents composed of RNA
Viroids and Virusoids
What are the 3 Classification Schemes ?
Domain Bacteria
Domain Archaea
Domain Eukarya - Eukaryotic
