Dr Nicholas Pearce, Head of the COVID-19 Task Team at the Universitas Academic Hospital, leads a dedicated team of professionals at the testing and vaccination site of the Universitas Academic Hospital, adjacent to our Bloemfontein Campus.

It is impossible to quantify the number of hours Dr Nicholas Pearce, Head of the COVID-19 Task Team for the Universitas Academic Hospital, spent working in response to this deadly virus since the first case was reported in South Africa last year. 

According to Dr Pearce, who is the Head of the Department of General Surgery in the Faculty of Health Sciences at the University of the Free State (UFS), the initial preparation phase required many hours of brainstorming, planning, and physical hours working on site. He also spent countless hours awake at night trying to come up with solutions for the many challenges faced along the way. This is in addition to being available telephonically twenty-four-seven for any issues related to equipment, staffing, and facilities.

“I was attending a vascular surgery congress in Germany last year January (2020) when China just announced the outbreak of COVID-19. I noticed an increased number of travellers wearing surgical masks at an airport in the Middle East when I was travelling to South Africa. 

“Upon my return to work, I approached management to discuss procurement of PPEs, as it was just a matter of time before COVID-19 would hit South Africa and the rest of the world. When things escalated, I was asked to head the COVID-19 response team at Universitas Hospital,” explains Dr Pearce.

Kind human being with a soft heart

Dr Pearce, who was brought up to always strive to be better, is driven and motivated to succeed. He has a very analytical brain and loves challenges. In fact, he does not believe in problems and only sees challenges. This kind human being can sometimes seem quite tough on the outside, but actually has a very soft heart. 

“I think it is human nature to want to feel needed. I have an inherent urge to help my fellow human beings. This is also the reason why I became a health-care professional and why I am passionate about teaching,” says Dr Pearce. 

With South Africa lagging behind with its vaccination programme, the hard work is far from over for Dr Pearce and his team. Says Dr Pearce: “The initiation of a mass vaccination site posed a whole new set of challenges, which once again required many hours of planning. The initial stages of running the vaccination site required many hours of physical hard work a day. Then there is also the daily operations meeting at 18:00 every weekday to discuss the vaccine roll-out in the province.”

Frustrations and setbacks

For Dr Pearce, this pandemic highlighted the differences between individuals from different social classes in our country. Providing quarantine and self-isolation facilities for individuals who do not have access to such facilities at home is one such example. 

“We all have a right to clean water and good quality healthcare. This also includes a right to oxygen. This right to oxygen has proved to be one of our great challenges in managing this pandemic. Delivery of these large amounts of oxygen has been especially challenging. Some days we require in excess of five tons of oxygen,” says Dr Pearce.

There have been many frustrations and setbacks on this journey, some of which can be quite demoralising and demotivating, but knowing that he is doing something good for his fellow human beings gives this gentle and diligent healthcare worker a tremendous amount of energy. “Positive feedback from patients and colleagues far outshines all the frustrations and disappointments,” concludes Dr Pearce. 


Outside of work

After finishing online meetings at home, Dr Pearce relaxes with his partner by chatting about the day’s events and cooking supper together while enjoying a glass of wine. He also tries to connect with family who lives in Gauteng. Because of work pressures and the pandemic, he has not been able to see them as much.

Plant scientists address wheat rust diseases at SASPP congress

In his research, Dr Botma Visser, researcher in the Department of Plant Sciences at the University of the Free State, highlighted the population dynamics of the stem rust fungus (Puccinia graminis f. sp. tritici) in Southern Africa. In recent years, two foreign stem rust races were introduced to South Africa, and a local virulence adaptation occurred in a third.

All of these races form part of the Ug99 group, a highly virulent collection of rust races endangering wheat production in many parts of the world. Despite the fact that half of the members of the Ug99 race group is prevalent in South Africa, Dr Visser’s work has clearly shown that Ug99 did not have its origin here. This emphasised the need to include neighbouring countries in the annual stem rust surveys, to proactively identify new races that could threaten local wheat production. In his research, Dr Visser also mentioned the way in which he has optimised modern molecular tools to accurately detect Ug99 isolates.

Dr Visser is one of three scientists from the Department of Plant Sciences that addressed delegates attending the biennial congress of the Southern African Society for Plant Pathology (SASPP) on the Bloemfontein Campus earlier this month on progress regarding research on wheat rust diseases conducted at the UFS.

Howard Castelyn, a PhD student in Plant Sciences, presented his research on quantifying fungal growth of the stem rust pathogen in wheat varieties displaying genetic resistance. This resistance, which is best expressed in adult plants, has the potential to remain durable in the presence of new rust variants. His presentation at the congress focused on optimising microscopic and molecular techniques to track fungal development in stem tissues of adult plants. These results now allow scientists to link rust infection levels and cellular responses with particular resistance genes expressed by the wheat plant, and contributing to the understanding and exploitation of durable resistance.

Prof Zakkie Pretorius presented his research, explaining how new genetic diversity for resistance to the stripe (yellow) rust fungus (Puccinia striiformis) is discovered, analysed and applied in South Africa. This research, conducted in collaboration with Dr Renée Prins and her team at CenGen, is unravelling the genetic basis of stripe rust resistance in a promising wheat line identified by Dr Willem Boshoff, a plant breeder at Pannar. The line and DNA markers to track the resistance genes will soon be introduced to South African wheat breeding programmes.

The rust research programme at the UFS contributes significantly to the successful control of these important crop diseases.

In addition to the contributions by the UFS, rust fungi featured prominently at the SASPP, with first reports of new diseases on sugar cane and Acacia and Eucalyptus trees in South Africa. A case study of the use of a rust fungus as a biological control agent for invasive plant species in the Western Cape, was also presented.
