Summary

Tuberculosis (TB) is transmitted in bioaerosols containing Mycobacterium tuberculosis (Mtb). Mtb-containing bioaerosols are likely related to host infectiousness and central to ongoing TB transmission. No routine diagnostic assay exists to measure Mtb in bioaerosols. Furthermore, published studies of Mtb in bioaerosol samples, have been limited to individuals with sputum-positive pulmonary TB. Currently TB diagnosis is based on clinical symptoms and sputum laboratory findings. However, approximately half of all patients commencing TB treatment are sputum negative resulting in a high proportion of presumptive treatments. We therefore propose to use a sensitive sampling protocol to investigate the prevalence of Mtb-containing bioaerosols in both sputum-positive and sputum-negative TB suspects.
