The results of many studies suggest that cows with SCC of less than 200,000 are not likely to be infected with major mastitis pathogens, but cows with SCC above 300,000 are probably infected (Smith, 1996). Herds with bulk tank SCC above 200,000 will have varying degrees of subclinical mastitis present. Data from the National Mastitis Council ...
Sub-Clinical mastitis : The form in which the milk and udder of the milch animal appear normal and can be diagnosed by testing of milk samples for various compositional changes and presence of pathogens and somatic cells. [1] per acute mastitis; acute mastitis; sub acute mastitis
The California mastitis test (CMT) is a simple cow-side indicator of the somatic cell count of milk. It operates by disrupting the cell membrane of any cells present in the milk sample, allowing the DNA in those cells to react with the test reagent, forming a gel. [1] It provides a useful technique for detecting subclinical cases of mastitis.
[1] The disease appeared to have a genetic component, and, after hereditary diseases known to affect other horse breeds were investigated, it was concluded that this was a newly identified disease. [1] The cause of disease was tracked down using a genome-wide association study, which implicated a region on horse chromosome 25. [1]

Options for the horse include sending the horse to a recognized research facility, branding the horse and quarantining it at least 200 yards from other horses for the rest of ...
This test can be easily done in clinical practice. The flow or milk from the inflamed nipple is placed on a sterile pad.
