Mastitis is a most frequent and costly disease of dairy cattle worldwide. All three contagious mastitis pathogens, Mycoplasma bovis, Streptococcus agalactiae and Staphylococcus aureus were investigated in 55 bulk tank milk samples from dairy cattle herds in Khon Kaen Province Thailand, by nested PCR and/or conventional bacterial culture. Bulk milk somatic cell count (BMSCC) was used as indicator for mastitis problem; i.e. > 5x105 somatic cells/ml of milk. The prevalence of Mycoplasma bovis, Streptococcus agalactiae and Staphylococcus aureus were 1.8%, 21.8% and 7.3%, respectively. Results from BMSCC indicated mastitis problem in 47 herds. However, 34 high-BMSCC with negative-contagious pathogen identification samples …
