Health Sciences Medal winners
Three of the Dean’s medal winners: Celine Taute, Angelique Johnson and Dr Monique Davidson after the graduation ceremony.

It was a big week for the newest University of the Free State (UFS) graduate, Angelique Johnson, who not only graduated with a Bachelor of Medical Science Honours in Pharmacology degree with distinction, but she was also awarded the Dean’s medal in the Faculty of Health Sciences at the university’s April graduation ceremonies.

Only a day before crossing the graduation stage on Friday 11 April, Angelique was also awarded the UFS Faculty of Health Sciences floating trophy for achieving the best results in respect of a bachelor honours degree in the faculty. 

“It’s honestly an honour. Receiving the Dean’s Medal feels surreal — it’s a reminder that the effort I put in didn’t go unnoticed. It’s also motivating and makes me feel proud to represent my faculty in such a positive way.

“Graduating with distinction feels incredibly rewarding — it’s a validation of all the late nights, hard work, and perseverance. Achieving this required discipline, time management, and a genuine passion for the material. I also leaned on a strong support system and made sure to stay consistent throughout the academic year,” says Angelique.

 

Dean’s Medal winners

The Dean’s medal was also awarded to Celine Taute, Alexander van Wyk and Dr Monique Davidson who all graduated last year. Taute, who graduated with a Bachelor of Medical Science with specialisation in Radiation Sciences degree (obtained with distinction), was awarded the Dean’s medal for achieving the best results as a third-year student. Van Wyk graduated with Bachelor of Biokinetics degree with distinction and received the Dean’s medal for achieving the best results as a fourth-year student while Dr Davidson received was awarded for obtaining the best results as a fifth-year student. 

Dr Davidson graduated with the degree Bachelor of Medicine and Bachelor of Surgery with distinction. Just like Johnson, Dr Davidson, Taute and Van Wyk was also awarded the faculty’s floating trophy for achieving the best results in their respective study years at Thursday’s (10 April 2025) prize-giving ceremony. 

 

Driven by passion 

According to Angelique, she will now pursue an MBChB degree as her passion for medicine drives her to go beyond simply making small changes — she wants to create a meaningful, lasting impact. “To borrow and adapt the words of Prof Gert van Zyl, Dean of the Faculty of Health Sciences, I don’t just aim to create ripples or waves in the field of healthcare — I aspire to create a tsunami of positive change in people’s lives and in the medical profession.”

In 2023 she completed a BSc in Human Physiology (cum laude) from the University of Pretoria (UP). She decided to enrol for an Honours in Pharmacology degree after developing a strong interest in how the body responds to different substances, especially at the cellular and molecular levels.

“Pharmacology felt like a natural extension of that curiosity — it dives deeper into the mechanisms of drug action and how they can be used to treat disease. I wanted to better understand how physiological processes can be manipulated for therapeutic benefit, and pharmacology offered the perfect balance between science and real-world medical application,” she concludes.

 

Provide comfort 

According to Celine, both the Dean’s medal as well as the awards came as a big surprise because she did not set out to achieve them. “I feel immensely blessed and thankful. Things that are worth it, require some sacrifices.” 

“I am so grateful. I set out to do my best and trusted that God would sort out the details. Discipline and hard work were key in my success. A person is not an island, so having family that always believed in me even when I didn't, helped me get through those tough exams,” says Celine. 

Celine, who is currently busy with an honour’s degree whereafter she will embark on a two-year internship, says she chose to specialise in radiation as she wanted to provide comfort and education to the mostly cancer patients and their families who radiation treatment can help.

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.
