Within the test for Indicative Homes colony morphology and indication response ought to be similar to that acquired While using the Beforehand permitted batch of media.
can we use streaking around the surface area of slective media as selective media use only or qualitative Examination?

This great site is absolutely linked to health care laboratory information for general public and well website being care experts.
In streaking method, aseptically have a loopful of organism from culture suspension (having less than a hundred CFU) as outlined in Desk-I for individual media and streak it on solidified agar area of sterilized or prepared new large amount media.
