RESUMO

The National Program of Brucellosis and Tuberculosis Control and Eradication (PNCEBT) designed by MAPA (Ministério da Agricultura Pecuária e Abastecimento) adapted as the central of vaccination by law with B19 the of all females of bovine and bubaline species, between three and eight months of age.

This studies evaluated the excretion of B19 strain in milk and urine of 14 bovine females the different ages that was immunized at three and eight months of age originated from heads of milky exploration, based on the bacteriologic tests and polymerize chain reaction (PCR) diagnoses correlated with hormonal fases of complete reproductive cycle.
