The aim of this study was to evaluate a simple and rapid DNA extraction method combined with a multiplex polymerase chain reaction (mPCR) for the identification of the major mastitis pathogens (Staphylococcus aureus, Streptococcus agalactiae, Escherichia coli and Mycoplasma bovis) from milk samples. Of the 200 California Mastitis Test (CMT) positive milk samples, 45 (22.5%), 21 (10.5%) and 11 (5.5%) were detected as positive for the presence of S. aureus, S. agalactiae and E. coli by culture, respectively. In mPCR by DNA isolation method optimised here, S. aureus, S. agalactiae and E. coli wer ...Daha fazlası
