Bio Quiz
1. What is the difference between a bactericide and something that is bacteriostatic? Bactericidal- Drug that kills bacteria Bacteriosstatic- Drug that limits or slows the growth of bacteria
a. What is a germicide?
An agent that kills germs, especially pathogenic microorganisms; a disinfectant.
Explain the realm of microbiology and the type of organism, which one would expect to study. The realm of microbiology is the domain- Three domains, Bacteria Archaea, & Eukarya.
What is a pathogen specifically? An agent that causes disease, especially a living microorganism such as a bacterium or fungus.
b. Be able to describe the theories of biogenesis and abiogenesis.
Biogenesis- The principle that living organisms develop only from other living organisms and not from nonliving matter.
Abiogenesis- The supposed development of living organisms from nonliving matter.
c. How do they relate to disease?
d. What are the contributions of Redi, Joblot, Needham, Pasteur, Lister, Leuwenhoek, and Koch?
Redi-disproves spontaneous generation for the 1st time
Joblot- proved the law of biogenesis was true.
Needham-
Pasteur- redefined the process of fermentation, proposed germ theory, discovered process of pasteurization (sterilization techniques)
Lister-introduced antiseptic surgery by chemical (phenol)
Leuwenhoek- reports the 1st observation of bacteria & protoxoans.
Koch- studied Anthrax bacterium and its transmission.
e. What are the postulates of the germ theory?
i. Postulate #1: the same microorganism must be present in every case of the disease ii. Postulate #2: the organism should be isolated from the tissues of the infected animal and grown in a pure culture iii. Postulate #3: the organism from the pure culture is inoculated into a healthy animal and the same disease should be reproduced iv. Postulate #4: the pathogen must be isolated from the experimental animal and shown to
