23
Q

The study of relationship between microbes and the environment.
● Example: The nitrogen cycle and other elemental cycle carbon, nitrogen, oxygen, sulfur, and
phosphorous cycles.

A substance produced by a microorganism that is effective in killing or inhibiting the growth of other microorganism.

A

Antibiotic

29
Q

TWO CLASSIFICATIONS OF DISEASES

A

Infectious Disease and Microbial Intoxication

30
Q

Results when a pathogen colonizes the body and subsequently causes disease.

A

Infectious Diseases

31
Q

When a person ingests a toxin.

A

Microbial Intoxication

32
Q

(poisonous substance)

Has been produced by microorganism

A

Toxin

33
Q

Scientist tells us that earth was formed about 4.5 billion years ago and for the first 800 million to 1 billion years of earth’s existence, there was no life on this planet.

A

First Mircoorganism on Earh

34
Q

By studying the mummies, scientists have learned that bacterial disease such as tuberculosis and syphilis and parasitic worm infections such as schistosomiasis, dracunculiasis (guinea worm infection) and tapeworm infections, have been around for a very long time.

A

Earliest known Infectious Disease

35
Q

first person to see live bacteria and protozoa.
 The father of Microbiology
 The father of Bacteriology
 The father of Protozoology

A

Anton van Leeuwenhoek (1632-1723)

36
Q

The idea that life can arise spontaneously from nonliving materials.

A

(Abiogenesis) Theory of Spontaneous Generation

37
Q

Disapprove theory of spontaneous generation and proved that life can only arise from preexisting life.

A

Theory of Biogenesis

38
Q

A German scientist who proposed theory of Biogenesis.

A

Rudolf Virchow in 1858.

39
Q

A French Chemist, made numerous contributions to the newly emerging field of microbiology and in fact his contribution is considered by many people to be the foundation of the science of microbiology and cornerstone of modern medicine.

A

Louis Pasteur (1822-1895)

40
Q

A German physician, made numerous contributions to the science of microbiology

A

Robert Koch (1843- 1910)

41
Q

Give some contributions of Robert Koch

A

KOCH’s Postulates
PURE CULTURE
Discovered Mycobacterium tuberculi
Mantoux agent

42
Q

Give some contributions of Louis Pasteur

A 
Wine Fermentation
Introduced Aerobes and Anaerobes
Pasteurization
Germ Theory of Disease
Infectious Agent that causes silkworm disease
43
Q

 Established during mid- to late 1800’s, experimental procedure uses to prove that a specific microorganism is cause of some specific infectious diseases.

A

KOCH’s Postulates

44
Q

Invented flat glass dish (petri dish) for culture of bacteria.

A

R.J Petri

45
Q

Refers to a condition in which only one type of organism is growing on a solid culture medium or in a liquid culture medium in the laboratory: no other types of organism are present.

A

PURE CULTURE

46
Q

Suggested the used of agar (a polysaccharide obtain from seaweed) as solidifying agent.

A

Frau Hess

47
Q

It is necessary to grow (culture) the pathogens in the laboratory IN VITRO in or on artificial culture media. However certain pathogens include viruses, rickettsia’s, chlamydia and the bacteria that causes leprosy and syphilis.

A

Exception to Koch Postulate

48
Q

Refers to something that occurs outside the living body, usually laboratory.

A

In vitro

49
Q

Refers to something that occurs within the living body.

A

In vivo

50
Q

They can only survive and multiply within the living host cells. Example. Viruses, rickettsia’s and chlamydia

A

OBLIGATE Intracellular pathogens

51
Q

Meaning fussy, microorganism having a demanding complex nutritional requirement. Organism can be grown in the laboratory by adding special mixtures of vitamins, amino acids and other nutrients to the culture media, others cannot be grown in the laboratory because no one has discovered what ingredients to add to the medium to enable to grow.

A

Fastidious

52
Q

CAUSE by not by one particular microorganism but by the combined effects of two or more different microorganisms. Example: acute necrotizing ulcerative gingivitis (trench mouth) and bacterial vaginosis

A

Synergestic Infection

53
