PRE-LAB QUESTIONS
1. In the Disease Transmission experiment, you will simulate exposure to a “pathogen.”
Predict whether the rate of exposure (the amount of contacts) will affect an
individual’s chance of becoming infected. Explain your reasoning.
The rate of exposure or amount of contacts is likely to affect an individual’s chance of
becoming infected. This statement is more accurate in the case of infectious diseases
where an infected person is expected to pass on the infection through contact with
another person. For instance, a person suffering from an airborne disease is more likely to
transmit that disease to others if he or she comes into proximity with an uninfected
person. The more people the infected persons come into contact with, the more likely
they are to expose the disease to healthy persons. Thus, where the exposure rate is high,
then the chances of an infected person acquiring the disease also becomes high. This
explains the reason why governments and health agencies initiate quarantine measures in
the event of a disease outbreak, as is the case with measles, the Ebola virus disease
(EVD), and other communicable diseases.
2. Why does an individual with antibodies for a species of Streptococcus bacteria not
automatically have immunity to all bacterial infections?
According to Pandey et al. (2016), bacterial immunity in individuals that have antibodies
for a species of streptococcus is limited due to a lack of immunological memory.
Immunological memory can be defined as the ability by the immune system to swiftly
and expressly identify an antigen that the infected person’s body has previously
encountered, and come up with the necessary immune response. As such, in the case of
streptococcus bacteria, it is difficult for an individual to be immune to all bacterial
