Towards a "human-like" model of tuberculosis: Local inoculation of LPS in lungs of Mycobacterium tuberculosis aerogenically infected mice induces intragranulomatous necrosis.

Cardona PJ, Llatjós R., Gordillo S., Díaz J., Ojanguren I., Ariza A., Ausina V. Scand J ImmunolCLAU: A 2000;52:156-63. The intravenous model of murine tuberculosis is less pathogenic than the aerogenic model due to a more rapid induction of systemic immunity.
