Question

The LIVE/DEAD viability stain has been used to study Pseudomonas aeruginosa biofilms, as discussed in the text. How could the LIVE/DEAD stain described in the chapter be helpful in specifically examining the regulation of explosive cell death in P. aeruginosa biofilm formation? Select the best answer. View Available Hint(s) Select the best answer.

You could stain biofilms at different stages of development with and without exposure to antibiotics to examine patterns of cell death because the living cells would stain green.

You could expose biofilms to antibiotics and then stain them to see which parts were harmed the most.

You could stain biofilms throughout the stages of development to determine normal patterns of cell death throughout the stages.

You could stain many biofilms, all at a similar stage of development.

Explanation / Answer

Since the P. augenosa biofilm undergoes explosive cell death due to some lytic enzyme or protein. No outer antibiotics may require. At different stages cells are examinie for there viability to study cell death pattern. Option A is correct.
