MICROBIO 4000 - EXAM 1 –
BULLWINKLE QUESTIONS AND
CORRECT ANSWERS
\.Why would Endospores (tough/protective/resistant formation formed by some
bacteria) cause problems for Pasteur's flask experiment? - ANSWERS✔-
Endospores would probably survive his initial boiling, contaminating the broth.
\.Arrange the following four steps/rules for Koch's postulates into the most logical
order? - ANSWERS✔-1) The microorganism must be found in abundance in all
organisms suffering from the disease but should not be found in healthy
organisms 2) The microorganism must be isolated from a diseased organism and
grown in pure culture 3) The cultured microorganism should cause disease when
introduced into a healthy organism 4) The microorganism must be re-isolated
from the inoculated diseased experimental host and identified as being identical
to the original specific causative agent
\.Microorganisms - ANSWERS✔-organisms that are too small to be seen with the
unaided eye
\.microbiology - ANSWERS✔-study of microorganisms
\.Are most microbes disease causing (pathogenic)? - ANSWERS✔-NO; most are
beneficial
