The aim of this study was to evaluate the somatic cell profile in the subclinical mastitis in dairy buffaloes in the Brazilian Northeastern. One thousand eight hundred ninety six milk samples from 474 buffaloes proceeding from four dairy farms located in the states of Pernambuco, Alagoas, Bahia and Ceará were analyzed. The lactic secretion was submitted to the California Mastitis Test (CMT) and the positive samples, from two crosses on were collected for the somatic cell count (SCC) and microbiologic exam. It was observed that the positive samples at the microbiologic exam presented SCC between 280,000 and 401,000 cells/mL with median of 328,000 cells/mL. It was concluded that SCC values above 280,000 cells/mL is an indication of mammary gland infection, however, the microbiologic exam of the milk is the best method for the diagnostic of subclinical mastitis in buffaloes. The observation of Staphylococcus coagulase-negative exerting influence in the SCC elevation must be subject of further studies in order to elucidate the pathogenicity of this group of microorganisms in mastitis of buffaloes. |
