Time-to-Detection in Culture of M. tuberculosis: performance for assessing index cases contact-positivity.

International journal of infectious diseases : IJID : official publication of the International Society for Infectious Diseases Jul 2023

Description

Time-to-Detection (TTD) in culture on liquid media is inversely correlated to bacillary load and should be a contributing factor for assessing tuberculosis transmission. We wanted to assess if TTD was a better alternative than smear-status to estimate transmission risk.
