Antibacterial Activity Assessment of Textile Materials: Parallel Streak Method

 

This test is a qualitative method to determine antibacterial activity of diffusible antimicrobial agents on treated textile material.

 

  • Suggested test organisms are Staphylococcus aureus ATCC #6538, and Klebsiella pneumoniae ATCC# 4352 to show antibacterial activity against a Gram positive and Gram negative bacteria.

  •  

  • The standard does allow other organisms to be used depending on the intended end-use of the test sample.

  •  

  • Sample strips are placed transversely across parallel streaks of bacteria that have been put on an agar surface.

  •  

  • The agar plates are then incubated for 18-24 hours at which time the plates are examined for a clear zone of inhibition, and observed in order to see if there is growth present under the test specimen.
