Dr Samantha Potgieter – in the front line of the fight against COVID-19 .


Dr Samantha Potgieter is an infectious disease expert at the Universitas Academic Hospital and affiliated Lecturer in the Department of Internal Medicine at the University of the Free State (UFS). She was also the first health-care worker to receive the Johnson & Johnson vaccine in the Free State. Prior to the COVID-19 pandemic, her main focus was on complicated HIV and drug-resistant TB as well as hospital-acquired infections. Since the emergence of COVID-19, she has been managing the COVID-19 clinical response at Universitas.

What is the best thing about your job?
I work in an amazing team with colleagues who, after 14 years, I can say have become friends.

What is the best and worst decision you have ever made?
Marrying the person that I did is by far the best decision I have ever made. And I must be honest, I regret very few of my decisions. Even the bad ones have turned out to be learning opportunities.

What was/is the biggest challenge of your career?
Navigating the COVID-19 pandemic as an infectious disease physician was by far the biggest challenge of my career. It was an equally fascinating learning curve and an immense privilege to be in a position to contribute.

What does the word woman mean to you?
The word woman means a million different things. We are daughters, wives, mothers, sisters, and friends. We are strong when we need to be and yet vulnerable with those we love. We can be powerful but kind. I love being a woman.

Which woman inspires you, and why?
My mom. She is hands down the kindest person I know. Her quiet strength and her grace – she is everything I strive to be.

What advice would you give to the 15-year-old you?
I spent a lot of time wondering what life is all about, and I still don’t have the answers. But I think I would tell the 15-year-old me to remember that life doesn’t have to be perfect or easy in order to be good.

What is the one self-care thing that you do? 
Cuddling my little ones – it’s my very favourite thing to do.

What makes you a woman of quality, impact, and care?
I am a woman, and I think all women are these things. We all have the capacity to care for those around us and to change our small corner of the earth for the better.
 
I cannot live without … my tribe of sisters, they make me laugh, they hold me up.
My secret weapon is … an early start to the day.
I always have … an extremely messy car (it’s really not my fault)
I will never … buy a pressure cooker – a good friend has put the fear of life into me!
I hope … that my daughter will grow up in a world where she will also be able to say that she loves being a woman.

The Next Generation Sequencing (NGS) unit at the UFS was established as an interdisciplinary facility under the Directorate for Research Development, Faculty of Health Sciences and Faculty of Natural and Agricultural Sciences.

The aim of the NGS facility is to aid internal and external investigators undertaking studies on Deoxyribonucleic acid (DNA) sequencing, assembly and bioinformatics approaches using the more advanced Illumina MiSeq NGS platform.

The NGS unit became operational in 2016 and is managed by Dr Martin Nyaga and administered through the office of the Dean, Faculty of Health Sciences, under the leadership of Prof Gert Van Zyl. Dr Nyaga has vast experience in microbial genomics, having done his PhD in Molecular Virology.

He has worked and collaborated with globally recognised centres of excellence in Prokaryotic and Eukaryotic genomics, namely the J. Craig Venter Institute and the Laboratory of Viral Metagenomics, Rega Institute, among others.

The unit has undertaken several projects and successfully generated data on bacterial, viral and human genomes. Currently, work is ongoing on bacterial and fungal metagenomics studies through 16S rRNA sequencing.

In addition, the unit is also working on plasmid/insert sequencing and whole genome sequencing of animal and human rotaviruses. The unit has capacity to undertake other kinds of panels like the HLA, Pan-cancer and Tumor 15 sequencing, among others.

Several investigators from the UFS including but not limited to Prof Felicity Burt, Prof Wijnand Swart, Dr Frans O’Neil, Dr Trudi O'Neill, Dr Charlotte Boucher, Dr Marieka Gryzenhout and Dr Kamaldeen Baba are actively in collaboration with the NGS unit.

The unit has also invested in other specialised equipment such as the M220 Focused-ultrasonicator (Covaris), 2100 Bioanalyzer system (Agilent) and the real-time PCR cycler, the Rotor-Gene Q (Qiagen), which both the UFS and external investigators can use for their research.

Investigators working on molecular and related studies are encouraged to engage with Dr Nyaga on how they would like to approach their genomics projects at the UFS NGS unit.
