Dr Anneke van der Spoel van Dijk is invested in contributing
to the global effort of stopping TB by 2035.
The work of Dr Anneke van der Spoel van Dijk investigates the spread of TB in the Free State population using techniques such as next generation sequencing, spoligotyping and MIRU-VNTR typing. Dr Van der Spoel van Dijk, a senior medical scientist in the Department of Medical Microbiology at the University of the Free State (UFS) also looks at drug resistance in her research. This work informs decisions about how best to treat patients with multidrug-resistant TB (MDR-TB).
She employs rapid molecular techniques to track one of Africa’s most serious diseases, tuberculosis (TB).
Drug resistance
Scientists assist the National Health Laboratory Service and Department of Health in trying to refine the diagnostic tools to identify these cases earlier. Dr Van der Spoel van Dijk explains: “Until recently, it took up to two years to fine-tune treatment decisions for patients with MDR-TB. Patients get a cocktail of anti-TB drugs, but it takes time to find the right combination. Re-infection and relapse (patients stopping treatment for several reasons) add to the diagnostic and treatment management challenges.
Enormous impact
“Now doctors can reduce the time needed for diagnostic certainty to about seven days, while new drugs allow reduction of treatment from more than 18 to nine months. This can have an enormous impact on the life of many patients.”
Dr Van der Spoel van Dijk’s work forms part of research in the faculty looking at resistance development in TB strains. She is currently also doing her doctoral thesis on the differences and incidence of MDR-TB among adolescents versus adults. Dr Van der Spoel van Dijk says: “It is a complicated picture, but we hope to unravel it to support better diagnostic tools and patient care.”
As part of the National Health Laboratory Service, her department is playing an important role in TB diagnostics and the training of scientists and future pathologists. “Our work is contributing to the global vision to stop TB by 2035,” Dr Van der Spoel van Dijk says.
Evolution of information and communication technology discussed as part of Darwin lecture series

Lectures on the evolution of the information and communication technology were recently presented by the University of the Free State's (UFS) Departments of Communication Science, Chemistry, Physics and Computer Science and Informatics. The lectures form part of the lecture series entitled The story of life and survival to celebrate 200 years since the birth of Charles Darwin presented by the UFS, Central University of Technology (CUT) and the National Museum. The lectures focused on communication in a manufacturing environment, the knowledge explosion and the broadband universe. It was preceded by an exhibition and demonstrations of various information and communication technologies, which was visited by about 1 000 secondary learners from schools in and around Bloemfontein. Here are, from the back: Prof. Jorrie Jordaan, CUT, Prof. Pieter Meintjes, Department of Physics at the UFS, Prof. Jannie Swarts, Department of Chemistry at the UFS and Ms Mercia Coetzee, Department of Communication Science at the UFS.
