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!

From wheat protein to perfect pizza

Barend Wentzel, an alumnus of the University of the Free State’s Department of Plant Sciences, is passionate about plant breeding. 

He literally eats and lives wheat proteins. In 1989 he initiated a breeding programme on arum lilies. “This breeding programme is at an advanced stage,” he said. Besides reading, playing the piano and accordion, Barend, due to the nature of his research at the Agricultural Research Council, also experiments with different types of ciabatta recipes made from sour dough. “I usually make my own pizza on Saturday evenings,” he said.

He is working at the Agricultural Research Council – Small Grain (ARC-SG) at the Wheat Quality Laboratory where he established a Cereal Chemistry Laboratory.

Complexity of flour quality

He explains that the focus of his research is on wheat protein composition. “The research conducted for my PhD study explains the complexity of flour quality to a certain extent, and it further emphasises the influence of the environment and genetic composition on selected baking characteristics. 

“Wheat protein can be divided into different types of protein fractions. These protein fractions contribute differently to dough properties and baking quality and the expression is affected by different components in the environment, including locality, rainfall and temperature. 

“Protein content alone does, however, not explain the variation in baking quality parameters, such as mixing time, dough strength and extensibility, and loaf volume.

“Several methods can be applied to quantify the different protein fractions. I am using high-performance liquid-chromatography (HPLC). The procedure entails the separation of a wheat protein extract through a column with chromatographic packing material. The injected sample is pumped through the column (known as the stationary phase) with a solvent (known as the mobile phase). The specific procedure, size-exclusion high-performance liquid-chromatography (SE-HPLC), is also used by the university’s Department of Plant Breeding, as well as in several international Cereal Chemistry Laboratories,” said Barend.

Dough strength and to loaf volume
“One of the highlights from the study was the positive contribution of the albumin and globulin protein fractions to dough strength and to loaf volume. The findings were wheat cultivar specific and the growing environment influenced the expression. The contribution of these protein fractions was much larger than previously reported for South African wheat cultivars,” said Barend. 
“Previous reports indicated that these protein fractions had a non-specific contribution to the gluten network during dough formation. The findings from this PhD justify further research on albumins and globulin proteins.” 

The Cereal Chemistry Laboratory at ARC-SG is involved in postgraduate student training under Barend’s guidance. He serves as co-promoter for several MSc and PhD students. He is also a collaborator on an international project with the International Maize and Wheat Improvement Centre (CIMMYT) in Mexico. Barend is furthermore working on improving wheat quality for processing and health purposes as a member of the expert working group of the International Wheat Initiative.
