PREAMBLE TO THE DESCRIPTIONThe following specification particularly describes the invention and the manner in which it is to be performed.FIELD OF THE INVENTION

[0001] The present invention relates to a device, system employing said device and a method of working said system to detect the presence of somatic cells. Particularly, this invention relates to an improved detection of somatic cells in bovine milk samples without the need for a laboratory or skilled persons, a system and method to do the same.BACKGROUND OF THE INVENTION

[0002] India has approximately 30 crore cattle, of which 25-30% suffer from a condition called mastitis caused especially due to unhygienic conditions of the milk production sites. Needless to say, the demand and production of milk are on a global level irrespective of the race, geographical location, sex or even age of the consumer which ranges from infants to the aged, all have been known to consume bovine milk.

[0003] Traditional methods of milking bovine involve rather unhygienic conditions where bacterial contamination is a prevalent factor, as a solution developed countries and now even some developing countries are adopting automated milk collection systems. However, even here concerns with equipment malfunction or by incorrect procedures or milking settings continue to exist; all of which lead to Bovine mastitis, an inflammatory response of the udder tissue in the mammary gland of the bovine caused due to physical trauma or micro-organism infections. It is considered the most common disease leading to atrophy of bovine mammary glands, a primary reason for the reduction of milk production and economic loss in dairy industries due to reduced yield and poor quality of milk.

[0004] Treatment of active mastitis infection is dependent mainly on antibiotics. However, the extensive use of antibiotics increases concerns about emergence of antibiotic-resistant pathogens. Therefore, the only feasible option is early detection,particularly at the stage of sub-clinical mastitis, which is difficult as detection of early-stage mastitis involves detection of somatic cells in milk which is typically performed in laboratory environment employing methods such as microscopy and flow cytometry, both of which are rather impractical to be adopted at the site of milk production, where such tests are needed.

[0005] As an on-site test, presently used tests involve the California mastitis test (AMT), pH test for alkalinity and the port a SCC strip test. However, the CMT is labor intensive, and the test Suffers from a Subjective interpretation by the individual user and an unacceptably high false negative rate.

[0006] None of the above are capable of quantitatively analyzing milk samples to classify the clinical stage of mastitis in order to accurately offer treatment to the animal. While US Patent 6,709,868 B2 claims to quantifiably detect WBC count in whole milk, the patent focuses on a chemical reaction culminating in a colour change, the quantity of WBC is subjectively detected based on this colour change. This test therefore fails to disclose a system independent of human error in subjectively analyzing the test samples.

[0007] There is, therefore, a need for a detection system, method and device to analyze dairy milk samples for early-stage mastitis independent of human intervention and errors associated with colorimetric readings; and to overcome at least one of the problems stated above.

[0008] For purposes of the present invention, "dairy animal” / “bovine” / “cattle” means any animal from which milk can be obtained. Non limiting examples of dairy animals are cows, sheep, goats, camels, and buffalo (bison). Tests for white blood cells for bovine can be used for other types of dairy animals as well. Thus, when thepresent Specification uses bovine as an example, the process is not limited to cows but is applicable to all types of dairy animals.SUMMARY OF THE INVENTION
