When streaking for isolation and utilizing semi-quantitative methods, the numbers of colonial growth in successive quadrants correlates directly with:
a. the microbiologist's streaking technique.
b. the relative amount of organism present in the original specimen.
c. the ability of the organism to grow on the media.
d. the type of incubation conditions.
B
When streaking for isolation, if properly performed, correlates directly with the amount of the organism present in the original clinical specimen. As the organism is dispersed during the process, the more organism present, the more growth that will occur in each successive quadrant of growth.
