Benefits of Staphylococcus aureus testing
One of the most
common types of chronic mastitis is caused by the bacteria, Staphylococcus aureus
(staph aureus). Often, it is subclinical, where there is neither
abnormal milk nor detectable change in the udder, but somatic cell count has
Using herd test
milk samples, the staph aureus test can be a convenient way of identifying whether
subclinical staph aureus is
a problem in a herd. It can enable more informed decisions for dry cow
treatment vs culling as part of an overall mastitis management plan.
About Staphylococcus aureus
attacks the tissue of the udder causing production loss during infection and
residual loss due to permanent udder damage.
Ongoing sub clinical infections can
result in recurrent clinical infections and the slow destruction of the udder. Infected
cows may have a fluctuating cell count and intermittent shedding of bacteria.
How Staphylococcus aureus testing works
We utilise milk samples from a
routine herd test to detect whether subclinical staph aureus is a problem in a
We can test a select group of
animals by either:
A list selected by the vet and
This will allow selection of
animals based on a combination of high SCC history, clinical history, past
treatments, potential new infections or any other selection criteria relevant
to the herd.
list selected by LIC based on agreed SCC criteria,
The SCC threshold will be
decided in consultation with the vet and farmer and a maximum number of samples
for testing can be specified.
When to test
Testing is recommended in later
lactation when staph aureus is the most common mastitis causing bacteria in
