The Southern African Association of Health Educationalists (SAAHE) recently bestowed the Council Medal Award – its highest accolade – on Prof Gert van Zyl, Dean of the Faculty of Health Sciences at the University of the Free State (UFS) in recognition of his extraordinary and sustained contributions to Health Professions Education (HPE) in Southern Africa.

The SAAHE Council Medal is awarded to individuals who have demonstrated long-term, impactful contributions to HPE, transforming pedagogy, advancing equity and diversity, and inspiring excellence in teaching, research, and engagement. Recipients must also demonstrate national and international recognition, as well as exemplary leadership, mentorship, and inclusiveness.

 

A transformative leader in medical education

Prof Van Zyl’s visionary leadership has been pivotal in shaping the future of medical education in South Africa. His strategic role in the development and implementation of the UFS’s five-year MBChB curriculum modernised the teaching and learning experience for medical students, aligning it with international best practice while addressing the specific needs of the South African healthcare context.

Speaking of his award, Prof Van Zyl expressed his gratitude and humility, acknowledging the collective efforts of colleagues, students, and institutional partners over the years. His recognition serves as an inspiration to the HPE community, illustrating the profound and lasting impact that dedicated leadership and innovation can have on the future of healthcare education.

Central to his transformative approach has been the integration of Interprofessional Education (IPE) and Community-Based Education (CBE). These innovative strategies ensured that medical training not only develops technical expertise but also nurtures collaborative practice and community engagement. Prof Van Zyl championed practical learning through CBE initiatives in Trompsburg and Springfontein, later expanding this model to Botshabelo, thereby fostering a strong culture of service to underserved communities.

 

A founding member and lifelong contributor to SAAHE

Prof Van Zyl’s association with SAAHE dates to its very inception in the early 2000s. As a founding member, he was actively involved in the organisation’s transition from the South African Association of Medical Educators (SAAME) to SAAHE, participating in the first meeting in Bloemfontein. His leadership and passion for HPE have been constant in the association’s growth and evolution.

His sustained commitment is evident in his 15 years of service on the SAAHE Executive Committee (2005-2020). Throughout this period he was instrumental in guiding the association’s strategic direction, ensuring that it remained a dynamic platform for advancing medical and health professions education.

Prof Van Zyl’s engagement extended well beyond committee work. He has been a consistent and influential presence at SAAHE conferences, contributing his expertise and thought-leadership at gatherings in 2006, 2007, 2012-2015, 2017-2019, and 2024. His presentations and discussions have enriched the dialogue around pedagogy, curriculum reform, and capacity building in HPE.

 

Advocate for mentorship, inclusivity, and capacity building

At the heart of Prof Van Zyl’s career is a deep commitment to mentorship and capacity development. Colleagues and students alike have benefited from his guidance, which blends academic excellence with a genuine investment in the growth and success of others. His leadership style has consistently promoted inclusivity and equity, fostering an environment in which diverse perspectives and talents can thrive in the service of excellence in HPE.

 

A deserving recognition of a lifetime’s work

The awarding of the SAAHE Council Medal to Prof Van Zyl is a fitting acknowledgment of his decades-long dedication to advancing HPE in Southern Africa. His transformative influence – spanning curriculum innovation, professional development, organisational leadership and community engagement – embodies the qualities the medal seeks to honour.

With this accolade, SAAHE not only honours Prof Van Zyl’s remarkable achievements, but also celebrates a career devoted to building a stronger, more inclusive, and forward-looking HPE landscape in Southern Africa.

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.
