Mission: Possible

Drs Pearce and Potgieter — Dr Samantha Potgieter, Senior Lecturer in the Department of Internal Medicine and Dr Nicholas Pearce, Senior Lecturer in the Department of Surgery comment on their team members’ commitment and determination during the pandemic.

On the forefront of the battle against the COVID-19 pandemic, two UFS doctors are leading a team of inspired healthcare workers in a superhuman effort to make a positive difference.

With the pandemic in its second year and the recurring challenges of new waves and strains consistently in the news, one would expect the doctors to be tired. However, quite the opposite is true. Upon entering the office where Dr Samantha Potgieter, Senior Lecturer in the Department of Internal Medicine and Dr Nicholas Pearce, Senior Lecturer in the Department of Surgery are in a meeting with colleagues, the debate is vibrant; an energetic sense of mission.

Miraculously succeeded

My brief is to collect stories and experiences they’ve had over the past 18 months at the Tumelo ward for general and high-care patients, where the team has miraculously succeeded in not running out of oxygen or ventilators, despite handling high volumes of patients from the Free State and Northern Cape. “We saw those pictures of piled-up bodies in Italy. We were committed to avoiding that at all costs. And we did.”

Success stories? First mentioned are their team members’ commitment and determination. The team had to stand in when families could not support dying patients. “They did not die alone. Our team was there.”

“Really sad and frustrating are the deaths that could have been prevented. Unvaccinated patients. They arrive ill, wanting to know if they can get it. Too late...” – Dr Nicholas Pearce

Then came hope

Sad stories? The past year has had its share of sad stories. “Someone comes in during the morning, needs oxygen, in the afternoon they are in ICU, then ventilator – and then they die. We’ve never faced anything like this before.”

Then came hope. Vaccines. Dr Pearce is in charge of the vaccination site at Universitas Hospital. “Really sad and frustrating are the deaths that could have been prevented. Unvaccinated patients. They arrive ill, wanting to know if they can get it. Too late ...” He opens his cell phone – shares the stats. “We can handle 2 000 vaccinations a day. At the moment about 250 comes in.” He shakes his head.

“We can beat this virus, but we need to stand together ...”

Extending new discoveries in the deep subsurface – UFS paper published in Nature Communications

2015-11-30

Scanning electron microscopy of some of the Eukarya recovered from two different mines. (a) Dochmiotrema sp. (Plathyelminthes), (b) A. hemprichi (Annelida), (c) Mylonchulus brachyurus (Nematoda), (d) Amphiascoides (Arthropoda). Scale bar, 50 µm (a,b), 100 µm (c), 20 µm (d).

Following the discovery of the first Eukarya in the deep subsurface (Nature, 2010) by a research group from the Department of Microbial, Biochemical, and Food Biotechnology at the University of the Free State (UFS) and their international collaborators, intense interest has developed in understanding the diversity of more complex organisms living in these extreme environments.

Prof Gaetan Borgonie from Extreme Life Isyensya, together with a group of UFS researchers, took this research further, resulting in a paper on this research released in Nature Communications – impact factor 11.47. This paper is an extension of the first reports of more complex life at great depths, and their abilities to survive these harsh conditions.

Ten authors from the UFS contributed with the array of expertise needed to define this discovery. The group was supported by staff from the different mining groups, long-term leading collaborators from the USA and Canada, and the idea specialist driver of the paper, Prof Borganie.

“After a sampling campaign that lasted more than two years, we identified that Platyhelminthes, Rotifera, Annelida and Arthropoda are thriving at 1.4 km depths in fissure water up to 12,000-years old in the South African mines of Driefontein and Kopanang,” said Prof Borgonie, who was appointed as associated researcher in the Department of Microbial, Biochemical, and Food Biotechnology.

This paper really opens a “can of worms” so to speak. According to Prof Esta van Heerden from the Department of Microbial, Biochemical and Food Biotechnology at the UFS they extended to define protozoa and fungi. “However, they are present in low numbers,” she said.

Characterisation of the different species reveals that many are opportunistic organisms. In house-adapted video equipment was used to film inside the fissure for the home of the organisms.

This is the first-known study to demonstrate the in situ distribution of biofilms on fissure rock faces using video documentation. Calculations suggest that food, not dissolved oxygen, is the limiting factor for population growth. The discovery of a group of complex multicellular organisms in the underground has important implications for the search for life on other planets in our solar system.
