Into the World of Hidden Microbes: Closing the Diagnostic Gap in TB
Tuesday, 14 April 2026 | 15h00 – 16h30 | CPD points available | Venue details and RSVP →
For 140 years, we've trusted Robert Koch's culture methods to detect tuberculosis. But what if the bacteria not detectable by conventional approaches are the most dangerous - invisible to diagnostics, unchecked in communities? Prof. Kana's research reveals a hidden world of differentially culturable tubercle bacteria (DCTB): viable TB organisms that standard diagnostics simply cannot see. In a prospective study of nearly 1,000 people, DCTB assays uncovered 79 completely missed infections and 18% more transmission events.

Prof. Kana directs a research and innovation unit at Wits. His work focuses on developing TB drugs that reduce treatment duration, advancing vaccine development, and establishing clinical cohorts to understand disease transmission and treatment responses. His research has produced diagnostic quality assurance products used in over 50 countries and spawned a biotech spinout. Recognised as an Early Career Scientist of the Howard Hughes Medical Institute, he has received the SAMRC Merit Award and the NRF Societal Impact Award.
