VetoRapid: A diagnostic tool designed for mastitis pathogen identification
VetoRapid
Vetorapid is a diagnostic tool that has been designed to aid in the easy identification of the most common bacteria found in mastitic milk samples. It is not intended to replace a high quality diagnostic laboratory but is a useful first line tool in basic identification of the main pathogens that cause clinical mastitis; E.coli, Staphylococci and Streptococci.

How to correctly take a sample for VetoRapid testing
Before doing any diagnostics, make sure to take milk samples first!

How to apply the milk sample to the Vetorapid plate
We recommend the use of a loop (metal loop or disposable loop) to apply the milk sample to the Vetorapid plate as results are easier to analyse with this method.
- Single colonies are easier to detect and there is better differentiation between possible growth and cloudiness caused by the smeared milk
- Plate the milk as shown in the picture (A) . Do this for all three sections.
(N.B. Sterile cotton swabs can also be used but can cause cloudiness making it harder to differentiate between this and possible growth; however this method can improve sensitivity).
Incubation of Vetorapid
Once the sample has been applied to the Vetorapid plate, label and incubate it at 35-37o C with the lid on facing downwards. Results should show within 18-36 hours. Most colonies are detectable within 24 hours.
