Step 1: Understanding the Concept:
Mastitis is an inflammatory condition of the udder.
It leads to an increase in somatic cells in milk.
Step 2: Key Formula or Approach:
No specific formula.
Need to know the tests used for mastitis detection.
Step 3: Detailed Explanation:
The sodium lauryl sulphate (SLS) test is based on the determination of somatic cells.
It detects the viscosity change caused by somatic cells.
The chloride test measures chloride content.
The catalase test measures catalase activity from somatic cells.
The resazurin test measures microbial activity.
Thus, the SLS test is based on somatic cells and viscosity.
Step 4: Final Answer:
The sodium lauryl sulphate test is based on somatic cells and viscosity.
Hence, the correct option is (B).
