How it Works

Cowside II is a broad-spectrum antibiotic inhibition test and it can run on your existing incubator equipment.[RG1] [BH2]

The kit consists of single-service vials that contain pre-measured bacterial spores, media and a pH indicator.

The process is straightforward. You add milk to the vial and incubate it. Set your timer for three hours.

The starting colour of the sample in the vial is purple.

During this period, if antibiotics are absent in the milk sample you’ve added, the spores will germinate and grow.

Once the spores generate acid, this will show up as a colour change in the vial to yellow.

But, if there are antibiotics present in the milk sample, then this will retard or inhibit microbial growth, not generating any acid. This means the sample will remain purple.

  • Antibiotic-positive samples stay purple, or are blue

  • Antibiotic-negative samples turn yellow or green.

These colour results are stable for up to 16 hours.
