Which of the following is NOT a method by which bacteria can be resistant to antibiotics?
Select one:
a. Utilise an alternate pathway of gene expression that is not targeted by the antibiotic.
b. Alter the binding site of the antibiotic, to either prevent it binding, or remove it from the site.
c. Production of enzymes that bind to and break down the specific antibiotic.
d. Production of a cell membrane pump that translocates antibiotics outside the cell.
A potential side effect of antibiotic use is a secondary bacterial or fungal infection, usually associated with regions like the skin, upper-respiratory tract or genitalia. What is the most likely reason for the formation of these secondary infections?
Select one:
a. Antibiotics do not work on viruses, so they are able to establish infections in these locations.
b. Organisms that are antibiotic resistant are usually more virulent, meaning they can survive and cause infection.
c. The antibiotic kills off normal flora, providing an…

a. the origin of transfer
b. the conjugation pilus

Some strains of Escherichia coli bacteria have acquired the ability to produce the harmful Shiga toxin, normally produced by Shigella dysenteriae. Which statements best explain why this occurs? Mark all that apply.
A. conjugation between two different species of bacteria allowed both strains of bacteria to express a virulence factor
B. transformation resulted in expression of a virulence factor
C. horizontal gene transfer between different species of bacteria
D. transduction of a specific gene resulted in expression of new traits
