Question

Explain why it is better to use isolated single colonies for evaluation as compared to growth in quardrant 1

Answer 1

It is difficult to isolate a particular type of bacteria from a clinical sample. Streak plate strategy is utilized to develop microorganisms on a growth media surface so individual bacterial colonies are isolated and diagnosed. Isolated provinces demonstrate a clone of cells, being gotten from a single antecedent cell. At the point when the chose culture media is inoculated utilizing a single isolated settlement, the subsequent culture develops from that chose single clone.

In 1st quadrant, there are so many species/strains of bacteria are present which can create confusion during diagnosis. So last isolated single colonies are selected.
