Milk Culture & Sensitivity (Mastitis)
Milk culture and sensitivity grows the bacteria causing mastitis from a clean quarter milk sample and tests which antibiotics may work against them. It helps a vet choose care for cows and buffaloes with mastitis.
- Sample
- Aseptic quarter milk sample
- Quantity
- As advised
- Report
- Confirmed when you book
- Collection
- Free in Bhopal
What this test checks
- The bacteria growing in milk from one udder quarter
- The type of bacteria, such as Staphylococcus, Streptococcus or E. coli, where it can be identified
- Which antibiotics stop the bacteria growing in the lab (the sensitivity test)
- Whether the growth looks like a true infection or contamination from skin, hands or air
Benefits of this test
- Names the bacteria behind mastitis, so care can be based on the cause.
- Shows which antibiotics may work and which are unlikely to.
- Helps your vet judge whether the infection spreads at milking or comes from the shed.
- Useful for mastitis that keeps coming back or has not settled with care.
- Supports careful use of antibiotics in the herd.

When your vet may advise it
- Mastitis that keeps coming back in the same cow or buffalo.
- Mastitis that has not settled with the care your vet has already given.
- Several animals in the herd getting mastitis around the same time.
- A quarter with a high CMT score or cell count, when your vet wants to know the cause.
- A new case of mastitis, with the sample taken before any antibiotic is started.
About this test
Milk culture and sensitivity is a lab test that grows the bacteria causing mastitis from a milk sample and then checks which antibiotics may work against them. Mastitis is inflammation of the udder, usually caused by bacteria. Many different bacteria can cause it, and they do not all respond to the same medicines. Knowing the cause helps your vet choose care for the animal and plan for the rest of the herd.
The sample comes from one quarter and must be collected cleanly, before any antibiotic is given into the udder or by injection. The lab places some of the milk on special plates that help bacteria grow, then identifies what grows. If a likely cause is found, it is tested against a set of antibiotics to see which ones stop it growing in the lab. This second step is called an antibiotic sensitivity test. Because the bacteria need time to grow, the reporting time is confirmed when you book.
The type of bacteria also tells your vet whether the infection is more likely to spread from animal to animal at milking time or to come from the surroundings, such as dung and wet bedding. A registered veterinarian reads the report with the animal's signs and history. A medicine that works on a lab plate does not always work in the udder, and a result with no growth does not always mean there is no infection. Call or WhatsApp the lab before sampling, so it can explain how to collect and send the milk from Bhopal or other districts.
How to prepare
Ideally your vet takes the sample: the teat is washed and dried, the first streams are thrown away, the teat end is wiped with spirit (alcohol), and milk goes into a sterile tube before any antibiotic, then it is kept chilled. The lab confirms the method, sample needs and reporting time when you book.
Reading the result
A registered veterinarian reads the report with the animal's signs and treatment history. Bacteria that stop growing on a lab plate may not always respond in the udder. No growth does not always rule out infection, because some bacteria are shed on and off and earlier antibiotics can stop growth. Mixed growth may mean the sample was contaminated and needs repeating.
Questions about Milk Culture & Sensitivity (Mastitis)

Before you book this test
Why this notice: so you know, before you book, how a test is done, what its limits are and who is responsible.
- Where it is tested. Some tests are done wholly or partly by an independent partner laboratory. The lab tells you before booking if this test is sent out, and the report names the laboratory that did it.
- What a result can and cannot tell you. No test is right every time. A normal result does not rule out every disease, and an abnormal result does not prove one. A registered veterinarian should read the report with the animal’s signs and history before any treatment is started, changed or stopped.
- The sample. A sample that is clotted, too small, wrongly labelled, leaking or too old may be rejected or reported with a note, and the lab may ask for a fresh one.
- Reporting time. Confirmed when you book. Times are estimates, not guarantees, and the lab confirms the time when you book.
- Emergencies. A booking or a pending report must not delay urgent care. If an animal has collapsed, struggles to breathe, has fits or bleeds heavily, call a veterinarian at once.

Mastitis Testing: CMT, Cell Count, Culture and RT-PCR
Mastitis testing works like a ladder. A cowside CMT shows which udder quarter is inflamed, a cell count measures how much, a culture finds the germ and shows which antibiotics may work, and RT-PCR finds germs that are hard to grow.
