Heinrich Janse van Rensburg’s is a 5th year medical student from the University of the Free State whose photo was highly commended at the Imperial College London’s Global Creative Competition: Medical Student Responses to COVID-19.

A late-night photo taken through a window at the Pelonomi hospital by a final-year medical student from the University of the Free State (UFS) was highly commended at the first Global Creative Competition: Medical Student Responses to COVID-19.

The competition, held by the Imperial College London, received more than 600 entries from more than 52 countries. The competition was held to bring together the global community of medical students to submit their creative responses to COVID-19 and to provide a platform for them to reflect on their personal and professional experiences during this challenging time.

Medical students from around the world could enter in two categories; visual and literary, and the winners were announced during a Global Awards Ceremony on 14 October.

Meaning behind the photo

Heinrich Janse van Rensburg’s late -night photo highlights the economic inequality that persists in South Africa. The photo was taken from the Pelonomi Hospital which is located in Heidedal, Bloemfontein, and shows the old, forsaken Dutch Reformed church in the foreground, shacks in the background with smoke billowing from the dwellings, where up to six people live in one room trying to stay warm during winter. They are built so close to each other that there can be no talk of effective social distancing.

According to Janse van Rensburg the theme of inequality in the South African milieu is further shown in the striking contrast between light and dark in the picture. “And now, with the COVID-19 pandemic placing a massive burden on an already struggling healthcare system the inequality is even more visible,” says Janse van Rensburg.

A little shocked 

He was a little shocked when he heard his photograph was highly commended. Janse van Rensburg says: “Imperial College London is a big institution and being an international competition I did not really expect a lot. There were participants from over 52 countries, and having seen some of the works that were submitted it feels special to be one of the students being noticed.”

Janse van Rensburg, who has never considered doing art, heard about the competition through the Faculty of Health Sciences platforms during lockdown level 5. He saw it as an opportunity to reflect, which has become even more imperative in times like these.

He says he does not go searching for art, but “notices” it from being conscious – something he thinks is important in medicine and life.

Value of creativity in promoting mental well-being

Dr Lynette van der Merwe, undergraduate medical programme director, School of Clinical Medicine, congratulated Janse van Rensburg, saying this commendation in an international competition underscores his talent and the value of creativity in promoting mental well-being.

“Heinrich’s artwork and showcase precisely what we aspire to develop in our exceptional UFS doctors-in-training: a professional with self-awareness, empathy and humanity.

“We initiated a Mental Health Awareness initiative and art competition in the School of Clinical Medicine in 2018 to promote creative expression as a means of supporting students’ mental health. Heinrich has won awards with his creative contributions every year, exhibiting his imaginative ability.”

Surgery and photography

Janse van Rensburg says he has always loved beautiful things and the meaning people attach to art is a good way to communicate that. He has applied for an internship at the Mitchells Plain hospital for when he completes his studies at the end of this year and is thinking of specialising in reconstructive or pediatrics surgery. Besides that, he would like to tap into his creative side and continue with the photography.

Research eradicates bacteria from avocado facility

“The aim of my project was to identify and characterise the contamination problem in an avocado-processing facility and then to find a solution,” said Dr Amy Strydom, postdoctoral fellow in the Department of Microbial Biochemical and Food Biotechnology at the University of the Free State (UFS).

Her PhD, “Control of Listeria monocytogenes in an Avocado-processing Facility”, aimed to identify and characterise the contamination problem in a facility where avocados were processed into guacamole. Dr Strydom completed her MSc in food science in 2009 at Stellenbosch University and this was the catalyst for her starting her PhD in microbiology in 2012 at the UFS. The research was conducted over a period of four years and she graduated in 2016. The research project was funded by the National Research Foundation.

The opportunity to work closely with the food industry further motivated Dr Strydom to conduct her research. The research has made a significant contribution to a food producer (avocado facility) that will sell products that are not contaminated with any pathogens. The public will then buy food that is safe for human consumption.


What is Listeria monocytogenes?

Listeria monocytogenes is a food-borne pathogenic bacterium. When a food product is contaminated with L. monocytogenes, it will not be altered in ways that are obvious to the consumer, such as taste and smell. When ingested, however, it can cause a wide range of illnesses in people with impaired immune systems. “Risk groups include newborn babies, the elderly, and people suffering from diseases that weaken their immune systems,” Dr Strydom said. The processing adjustments based on her findings resulted in decreased numbers of Listeria in the facility.

The bacteria can also survive and grow at refrigeration temperatures, making them dangerous food pathogens, organisms which can cause illnesses [in humans]. Dr Strydom worked closely with the facility and developed an in-house monitoring system by means of which the facility could test their products and the processing environment. She also evaluated bacteriophages as a biological control agent in the processing facility. Bacteriophages are viruses that can only infect specific strains of bacteria. Despite bacteriophage products specifically intended for the use of controlling L. monocytogenes being commercially available in the food industry, Dr Strydom found that only 26% of the L. monocytogenes population in the facility was destroyed by the ListexP100TM product. “I concluded that the genetic diversity of the bacteria in the facility was too high and that the bacteriophages could not be used as a control measure. However, there is much we do not understand about bacteriophages, and with a few adjustments, we might be able to use them in the food industry.”

Microbiological and molecular characterisation of L. monocytogenes

The bacteria were isolated and purified using basic microbiological culturing. Characterisation was done based on specific genes present in the bacterial genome. “I amplified these genes with polymerase chain reaction (PCR), using various primers targeting these specific genes,” Dr Strydom said. Some amplification results were analysed with a subsequent restriction digestion where the genes were cut in specific areas with enzymes to create fragments. The lengths of these fragments can be used to differentiate between strains. “I also compared the whole genomes of some of the bacterial strains.” The bacteriophages were then isolated from waste water samples at the facility using the isolated bacterial strains. “However, I was not able to isolate a bacteriophage that could infect the bacteria in the facility.
