It is used even in areas where laboratory facilities are available for diagnosis and monitoring program purposes. CMT usually score , where 1 indicates a completely negative reaction and increasing degrees of inflammatory reaction of the udder. The reactions , or may be considered as indicative of subclinical mastitis, because they are related to an increase of the somatic cell count SCC in the milk.
This variation, however, may produce either false-positive or false-negative results. A total of 3, quarter milk samples from lactating cows were examined. CMT was evaluated at the moment of sampling at cow side and SCC in the laboratory, with a fluoro-opto-electronic method Fossomatic Foram utilizadas 3. Para identificar corretamente contagens acima de O reagente do CMT foi preparado com detergente comercial, de acordo com Langenegger et al.
Consideraram-se as contagens de Do total de 3. Considerando os limites de O escore 2 correspondeu a , Para a CCS de Essas vantagens foram confirmadas no presente trabalho. O limite de Os resultados obtidos com os testes de especificidade comprovam os dados obtidos por Casura et al.
