RESUMEN

La transmisión de la tuberculosis bovina (TB) a través de aerosoles representa un fenómeno poco caracterizado en la infección natural. Con el objetivo de estudiar la frecuencia de excreción de Mycobacterium bovis vía respiratoria y su relación con la respuesta inmune, se analizó durante seis meses la presencia de bacterias del complejo M. tuberculosis en exudados nasales, utilizando PCR anidada, en un hato de bovinos lecheros con alto riesgo de transmisión de TB. Los resultados confirmaron la excreción de M. bovis vía respiratoria, colateralmente a la transmisión de TB en este hato, sugiriendo además la influencia de INF-γ en este fenómeno.
