Prof Felicity Burt is a passionate virologist with more than 25 years of research on medically significant viruses that cycle in nature and are transmitted to humans via mosquitoes, ticks, or animals.

Prof Felicity Burt, an expert in arbovirology in the Division of Virology, has been leading the University of the Free State (UFS) COVID-19 Task Team over the past five months. Prof Burt is a passionate virologist with more than 25 years of research on medically significant viruses that cycle in nature and are transmitted to humans via mosquitoes, ticks, or animals.

As the UFS is celebrating its champion women this Women’s Month, Prof Burt gives us some insight into who she is. 

Please tell us about yourself

I am an arbovirologist from the Division of Virology in the Faculty of Health Sciences, and the National Health Laboratory Service. Who am I? I am a mum, a wife, a daughter, a sister, a sister-in-law, a friend, a scientist, a colleague, a professor.  I am passionate about my work and have spent more than 25 years researching medically significant viruses that cycle in nature and are transmitted to humans via mosquitoes, ticks, or animals. 
My research group investigates the various mechanisms that viruses use to cause disease, and I am particularly interested in how our bodies respond to infection that can help us develop vaccines or therapies. Raising awareness of these viruses, profiling disease associated with different viruses, and developing tools for surveillance programmes all contribute towards understanding pathogens and the public-health implications. I am so grateful for the opportunities my career has provided me, which includes travelling all over the world for conferences and meetings and participating in outbreak responses in Africa.   
   
Is there a woman who inspires you and who you would like to celebrate this Women’s Month, and why?

I am inspired by all women who set goals and work to achieve them. The goals may vary, but they are important and challenging to each individual.  Hence, I would like us to acknowledge and celebrate all women who achieve their goals through hard work, dedication, and of course, plenty of passion. 

What are some of the challenges you’ve faced in your life that have made you a better woman?

I have always been quite a shy person and still find it challenging to stand up in front of an audience. I was born in Zimbabwe and when I finished school, I moved to South Africa to study at the University of the Witwatersrand. Moving on my own to Johannesburg at the age of 18 was definitely a challenge for a quiet, reserved girl from Harare. Compared to home, Johannesburg was a mammoth city; however, I absolutely loved university life, met people who became lifelong friends, and pursued a career in science. I try to learn from my many mistakes and treat others how I would like to be treated, especially with kindness. 

What advice would you give to the 15-year-old you?

Dream on girl, and it doesn’t matter if they don’t all come true; life isn’t going to turn out as expected, but as long as you enjoy the journey. You don’t have to be the best, but you have to do your best – with passion of course. 

What would you say makes you a champion woman [of the UFS]?

To be honest, I wouldn’t call myself a champion, but I am quite proud of what I have established at the UFS. With hard work and passion, contributions from colleagues, support from management, and never forgetting a whole bunch of wonderfully enthusiastic students, we have built an active postgraduate research group, graduated multiple students, published scientific articles in international journals, presented our research at conferences, contributed to community engagement, had fun, and still have plenty more to achieve!

Plant-strengthening agent enhances natural ability of plants to survive
2015-07-27

Drought, diseases, and fungi. These are factors that farmers have no control over, and they often have to watch despondently as their crops are damaged. In addition, the practice of breeding plants in special and strictly-controlled conditions, has resulted in crops losing the chemical ability to protect themselves in nature.

Researchers in the Department of Soil, Crop, and Climate Sciences at the University of the Free State (UFS) have developed an organic agent that restores this chemical imbalance in plants. It enables the plant to build its own resistance against mild stress factors, and thus ensures increased growth and yield by the plant.

ComCat®, a plant-strengthening agent, is the result of extensive research by the German company, Agraforum AG, together with the UFS. Commercialisation was initially limited to Europe, while research was done at the UFS.

“Plants have become weak because they were grown specially and in isolation. They can’t protect themselves any longer,” says Dr Elmarie van der Watt from the department.

Dr Van der Watt says that, in nature, plants communicate by means of natural chemicals as part of their resistance mechanisms towards various stress conditions. These chemicals enable them to protect themselves against stress conditions, such as diseases and fungi (biotic conditions) or wind and droughts (abiotic conditions).

Most wild plant varieties are usually well-adapted to resist these stress factors. However, monoculture crops have lost this ability to a large extent.

The European researchers extracted these self-protection chemicals from wild plants, and made them available to the UFS for research and development.

“This important survival mechanism became dormant in monoculture crops. ComCat® wakes the plant up and says ‘Hey, you should start protecting yourself’.”

Research over the last few years has shown that the agent, applied mostly as a foliar spray, subsequently leads to better seedlings, as well as to growth, and yields enhancement of various crops. This is good news for the agricultural sector as it does not induce unwanted early vegetative growth that could jeopardise the final yield ? as happened in the past for nitrogen application at an early growth stage.

“The use of synthetic agents, such as fungicides which contain copper, are now banned. Nowadays, options for natural and organic agriculture is being investigated. This product is already widely used in Europe, but because farmers are often swamped by quacks, the South African market is still somewhat sceptical.”
