________________
3 multiple choice options
A strain of the Gram-negative bacterium Vibrio cholerae, the ability to bind to a host target cell
which causes the diarrheal disease cholera, has a 3 multiple choice options
mutation that causes the bacterium to lose the ability to
produce fimbriae which caused it to become less
virulent. What function has this pathogen lost?
Pathogenic strains of Gram-positive Staphylococcus a protease called staphylokinase
aureus dissolve clots to help spread to different regions 3 multiple choice options
of the body by producing and secreting ____________
Gram-negative Haemophilus influenzae bacteria, which they need heme to bind iron for transport and acquisition in the cell
cause respiratory and ear infections, require heme for 3 multiple choice options
their growth because _________________
Which of the following is a primary advantage for a the bacteria can hide and be protected from antibodies and immune cells
bacterium having the ability to invade and reside inside 3 multiple choice options
host cells?
A strain of the Gram-negative bacterium Shigella flexneri, the ability to escape the phagosome and enter the cytosol
which causes the disease dysentery (bloody diarrhea), 3 multiple choice options
has a mutation that causes this intracellular bacterium to
lose the ability to produce a pore-forming toxin that
makes pores phagocytic membranes and so it has
become less virulent as a consequence. What function
has this pathogen lost?
Lipid A is _______ that stimulates the body to release an endotoxin found in bacterial membranes
hormone-like chemicals (called cytokines) that cause 3 multiple choice options
fever, inflammation, diarrhea, hemorrhaging, shock, and
blood coagulation
