Descripción:	The real prevalence of contagious mastitis pathogens was calculated in the herds belonging to Minas Gerais Holstein Association (MGHA). One bulk milk sample was collected from 40 herds to identify Staphylococcus aureus and Streptococcus agalactiae using selective media. The real prevalence of S. aureus and S. agalactiae was calculated based on apparent prevalence, sensitivity and specificity from previous study performed in Brazil. The real prevalence of S. aureus and S. agalactiae was 93% and 41%, respectively. The results showed high prevalence of S. aureus and S. agalactiae in these herds. The adoption of control measures considering epidemiological features of each pathogen and prevalence of infected cows within each herd should be considered with objective of reducing the new infection rate and infection time. The main approach in control and prevention of S. agalactiae should be directed to eradication of this pathogen through treatment of infected cows. In contrast, the approach in control measures of S. aureus should be based mainly on culling of cows with chronic infection.
