AATCC 147

Assessment of Antibacterial Finishes on Textile Materials via the Parallel Streak Method

Test Purpose
The purpose of this microbiology lab test is to evaluate the basic antibacterial activity of a treated textile material against selected bacteria by determining the zone of inhibition. This test is typically used for development purposes.

Test Summary
Five streaks of bacterial cells are spread onto an agar surface using a sterile inoculating loop. The test sample is placed transversely in contact with the inoculated surface. Following incubation, the agar surface was examined for inhibition of the test organism growth.
