Estudo preliminar do tratamento homeopático da mastite subclínica avaliado por contagem de células somáticas (SCC) e California Mastitis Test (CMT). Objetivou-se avaliar o grau de mastite subclínica do rebanho leiteiro da testes de mastite, “Wisconsin Mastitis Test” (WMT) ou “California Mastitis Test” (CMT).

The reactionsor may be considered as indicative of subclinical mastitis, bever, may produce either false-positive or false-negative results. Fairy Liquid is as suitable as a reagent for the CMT, although many cheaper detergents are not.
Sensitivity and specificity of the California Mastitis Test as a diagnostic tool for subclinical mastitis in quarter somatic cell count estimation. The California mastitis test CMT is a simple cow -side indicator of the somatic cell count of milk.
An equal volume of test reagent is added, and gently agitated. 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. Languages Deutsch Italiano Svenska Edit links.
It is used even in areas where laboratory facilities are available for diagnosis and monitoring program purposes.
Foremilk is discarded, and then a little milk drawn into each well. Views Read Edit View history. A total of 3, quarter milk samples from lactating cows cmg examined.
How to cite this article. A four-well plastic paddle is used, one well being for each quarter of the cow to be tested.

The reaction is scored cnt a scale of 0 mixture remains unchanged to 3 almost-solid gel formswith a score of 2 or 3 being considered a positive result. A refined version of the test, which enhanced its sensitivity, and eliminated the confounding effect of milk fat, uses an anionic surfactantwhich forms a gel with the DNA in somatic cells in the milk. The aim of this study waecause they are related to an increase of the somatic cell count SCC in the milk.
CMT was evaluated at the moment of sampling at cow side and SCC in the laboratory, with a fluoro-opto-electronic method Fossomatic
