Africa Month celebration on the UFS South Campus
Attending the Africa Month celebrations on the UFS South Campus were, from the left: Temba Hlasho, Executive Director: Student Affairs; Thandeka Mosholi, Head: Social Responsibility, Enterprise, and Community Engagement; Prof Colin Chasi; Ms Zola Thamae; Prof Francis Petersen; Simphiwe Dube, South Campus SRC President; Dr Cornelius Hagenmeier, Director: Office for International Affairs; Poloko Masuelele; Nombulelo Shange, Lecturer in Sociology; and Bulelwa Moikwatlhai (seated), Office for International Affairs.

Amid great fanfare, colour, and song, the South Campus of the University of the Free State (UFS) kicked off Africa Month in celebration of education on the African continent.

Delivering welcoming remarks on behalf of Dr Marinkie Madiope – the South Campus Principal – was Poloko Masuelele, Assistant Director heading the Curriculum Design and Development Unit on the South Campus. “The African continent is suffering a great deal of challenges, including the scourges of malnutrition and strained delivery of basic education. How revolutionary would it be if we could simultaneously eradicate these vices by formulating policies, mechanisms, and vehicles that would enable us to feed, heal, and teach our people? It is incumbent on us as thought leaders to take the lead in this significant enterprise.”

Bringing a government prospect, was Ms Zola Thamae, the Acting Director in the Free State Department of Sport, Arts, Culture and Recreation. She stated that there is much that could be done to address challenges in Africa if the university and government take hands. She also urged students to read and educate themselves in order to change their background. 

Searching for African solutions

Prof Francis Petersen, Rector and Vice-Chancellor of the UFS, delivered the keynote address. Focusing on the theme of Africa Month, he said when it comes to educational development, there is no other continent that has faced the same trials and challenges as ours. “But in the harsh crucible of history, character, tenacity, and a sense of ubuntu were forged, translating into an exciting, fertile breeding ground for new knowledge creation, independent thought, and innovation,” he added. 

He quoted Paul Kagame, President of Rwanda, who said, “Africa’s story has been written by others; we need to own our problems and solutions and write our own story,” and added that over the past few decades, on many fronts and in many spheres – also in education – this is exactly what has been happening.

“We are actively searching for African solutions to African problems. The value we can offer is substantial,” he said.

Prof Petersen expressed confidence not only in Africa’s people, but also in what they are bringing to the table. “While Africa has established itself as an attractive investment destination, it is now more sought after for its people than for its physical assets. And its people have been driving exciting and encouraging developments in education.”

“In terms of Africa’s contribution to global knowledge, the world is slowly but surely acknowledging the abundant evidence of scientific innovation contributed by African scholars – not only at present, but since the earliest times.”

He also trusts that Africans have advanced considerably in decolonialising curricula. “Across our continent, African history, achievements, and discoveries have been absorbed into school curriculums, replacing a Eurocentric focus in education, and fulfilling the vision of Africans owning their own story. Most higher education institutions – the UFS included – have over the past decade or two also been engaged in a comprehensive, systematic process of decolonising our curricula – incorporating the knowledge created on our own continent in various study fields.”

Despite these encouraging milestones that education has reached in Africa, Prof Petersen is of the opinion that much remains to be done. “As custodians of higher education in Africa, and as part of the larger education sector, we have our work cut out for us,” he stated.

He believes that the unique point in time in which Africa finds itself presents an opportunity to completely reimagine the entire education landscape.

Collectively we will succeed

Also contributing some valuable input to the celebratory event, was Prof Lynette Jacobs, Associate Professor in the Department of Open and Distance Learning. She stated that one of the problems of colonial education is that it does not cultivate African self-esteem. Quoting President Julius Nyerere, she shared that “Education should not alienate students from their traditions but should rather make them appreciate themselves as Africans.” 

According to her, Africans have lost the confidence to celebrate themselves in their African cultures and traditions within the formal education environment.

“Collectiveness, togetherness, dialogue, and being authentically human are what Africa brings to the world. The world has so much to learn from Africa,” she said and asked the audience, “Do you embrace who you are and are you proud to share it with the rest of the world?”

Representing the Unit for Institutional Change and Social Justice was Prof Colin Chasi. He emphasised the importance of working together to bring about positive change in Africa. “We enhance our capacity if we are working together. Collectively we will succeed; separately we will suffer a terrible fate,” he stated.

“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.
