Tuberculosis due to Mycobacterium bovis and Mycobacterium caprae in sheep

Tuberculosis was diagnosed in three flocks of sheep in Galicia, Spain, in 2009 and 2010. Two flocks were infected with Mycobacterium bovis and one flock was infected with Mycobacterium caprae. Infection was confirmed by the comparative intradermal tuberculin test, bacteriology, molecular analysis and histopathology. Sheep have the potential to act as a reservoir for tuberculosis.Ana Balseiro is the recipient of a Contrato de Investigación para Doctores from the Instituto Nacional de Investigación Agraria y Agroalimentaria (INIA).
