Infection of Mice with Aerosolized Mycobacterium tuberculosis: Use of a Nose-Only Apparatus for Delivery of Low Doses of Inocula and Design of an Ultrasafe Facility

摘要

Aerosolized delivery of virulent or hypervirulent Mycobacterium tuberculosis requires careful consideration of methodology and safety. To maximize safety, we installed a nose-only aerosol apparatus that can reproducibly deliver a low dose (<100 CFU per mouse) of M. tuberculosis in a carefully designed biohazard facility.
