Prof Gert van Zyl, Dean of the Faculty of Health Sciences, welcomed guests at the official launch of the faculty’s new programmes, the Master of Public Health and PhD Public Health in the Division of Public Health.

What started seven years ago as a dream, came to fruition in October 2024, when the Faculty of Health Sciences at the University of the Free State (UFS) officially launched two new programmes, the Master of Public Health and PhD Public Health in the Division of Public Health (DPH).

In his welcome address, Prof Gert van Zyl, Dean of the Faculty of Health Sciences, said it is a significant milestone launching these particularly important programmes in the faculty. The launch took place on 24 October 2024 at the James Moroka Building on the Bloemfontein Campus. These programmes are dedicated to recognising and responding to complex national and global public health challenges through high-quality research, teaching and learning, and engaged scholarship.

Prof Bonang Mohale, UFS Chancellor, and Dr BE Mzangwa, Acting Deputy Director General of the Free State Department of Health and CEO of the Universitas Academic Hospital, were also in attendance, while Mr Ramphelane Morewane, Deputy Director General of HIV/AIDS, TB, Maternal and Child Health, in the National Department of Health, delivered a congratulatory message virtually.

Said Prof Van Zyl: “The vision of the public health dream in the faculty started with a small group of us having a discussion on taking public health forward. At that first meeting we already agreed on an action plan. We knew then if we kept true to this dream, we would have success, but this success would not be for us. It would be for the influence of the lives of many postgraduate students that will enrol in the programmes in this division and uplift themselves by getting a quality and relevant qualification. Ready to serve the bigger community.

“For those who are part of the vision of the public health dream, remember the dream and vision, continue with the collaborative efforts and spirit, remain committed to the dream and do everything that is needed to allow it to excel, and never forget the core values we embraced at the beginning when we started this dream,” said Prof Van Zyl.

Addressing public health challenges

Prof Anthea Rhoda, Acting UFS Vice-Chancellor and Principal, said in a video message that the launch marks a significant milestone symbolising the beginning of an academic endeavour aligned with Vision 130, which emphasises academic excellence, quality and impact.

“Today’s launch represents a crucial step in the Faculty of Health Sciences’ commitment to address public health challenges within our communities, nationally, as well as globally. It also represents a crucial step in the University of the Free State’s dedication to tackling public health challenges that are prevalent in our communities.

“The Division of Public Health aspires to be engaging, diversifying public health through innovative, global responsive research. Public health, as is common knowledge, is the study and practice of safeguarding and improving the well-being of individuals and community. It includes the promotion of healthy lifestyles, the prevention of diseases and efforts to control infectious illnesses,” said Prof Rhoda.

She said it should be remembered that public health encompasses more than a simple field of study, it’s a commitment to service, and a promise to make a positive impact in the world. She is confident that this new programme will contribute significantly to the academic prestige of the UFS and will be a source of innovative solutions to the complex health challenges of the times.

Programmes in high demand

According to Prof Joyce Tsoka-Gwegweni, Vice-Dean: Research, Transformation, and Marketing and Head of the DPH, they only enrolled the first cohort of students in the second semester of 2023.

“During that time, we enrolled six Master of Public Health students and 14 PhDs. This year we enrolled 26 students, 13 in each programme. Currently we have 46 students. 19 Masters’ of Public Health and 27 PhD students, of which 90% are black female students. We also have international students from Lesotho, Namibia and Kenya. The quality of our students is very high. They are already working in health-related institutions and most of them are in leadership positions.

“For the coming year, 2025, we have already received 224 applications for the Master of Public Health programme and 30 for the PhD. We can only accommodate 30. Our programmes are already in high demand nationally and on the continent. They address a range of public health topics of national and international importance,” said the Vice-Dean.

Prof Tsoka-Gwegweni said because of the quality of staff and the quality and relevance of the programmes, their multidisciplinary nature, sustainability, and responsiveness to local, national and global public health challenges, these programmes are contributing to the UFS vision of achieving academic excellence, quality and impact; maximum societal impact with sustainable relationships; and of achieving a diverse, inclusive equitable university.

Health and prevention are primary

Prof Geoffrey Setswe, the Managing Director of the Aurum Research Institute, delivered the keynote address, saying public health, unlike medicine and nursing is not about treating individual patients, but focuses on the maintenance of promotion of health at a population level. Health and prevention are primary. He also talked about the public health pathways and career options in this field.

The best-known elements of public health, he said, are health promotion, environmental health, surveillance, communicable disease prevention, communication, health equity, emergency preparedness, harm reduction and home visiting programmes.

“The South African public health system is rebuilding itself and working to enhance health and well-being by implementing the NHI that will enable access to high quality, people-centred and integrated health care for all South Africans. Public health training must have multisectoral applications for public health careers, specialisation and advanced education providing life experiences and related expertise for people with diverse origins and ethical motivations,” he said.

According to Prof Setswe, this model will help in the training of public health professionals to deal with the quadruple burden of communicable diseases (HIV, TB, sepsis), non-communicable diseases (cancers, diabetes, cardiovascular diseases), injuries from crime and violence (including GBV), and mental health (including depression, para-suicide, risk behaviour, harmful substance abuse) and maternal and child health.

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.
