Pulmonary Lymphatics Are Primary Sites of Mycobacterium tuberculosis Infection in Guinea Pigs Infected by Aerosol

This is the authors' abstract. We don't add key points for this paper.

Mycobacterium tuberculosis causes a lymphatic vasculitis in the lungs of guinea pigs infected by a low-dose aerosol. This observation suggests that in addition to being a direct conduit from the lungs to the regional lymph nodes, pulmonary lymphatics are themselves sites of infection and could be the site of latent infection.
