Which of the following is NOT a membrane-disrupting toxin?
Vaselesa [24]

Answer:

Answer is A-B toxin.

Explanation:

A membrane-disrupting toxin is toxin that affect the cell membrane. The effect of its secretion  could be by interrupting the phospholipid layer or through pores formation on the membrane.

Membrane- disrupting toxins are regarded as  exotoxins. Examples are leukocidin and hemolysin which their effects cause leakages of the cytoplasmic content and lysis of the cell, through the formation of pores on the cell membrane.

If we have a plate that has 2500 colonies on it, can we use this plate to calculate CFU's
AleksAgata [21]

No, the solution with bacteria in it needs to be diluted in order to be in the range of 30 – 300.

A colony-forming unit –CFU is used to estimate the number of viable (ability to divide by binary fission) microbes in a sample.  

A sample of microbes is diluted and spread on a plate. Then, the number of colonies is counted, assuming that each colony have grown from a single colony-forming unit, or CFU.

Plates with more than 300 colonies are difficult to count while those with less than 30 colonies give statistically unreliable numbers of colonies to count.
