Prof Francis Petersen
Prof Francis Petersen, UFS Rector and Vice-Chancellor opened the workshop on Monday, 10 February 2020.

Will an enclaved state work in a country like South Africa? How can universities produce graduates who will become engaged citizens, and what is the current status of the ANC and the DA? These were some of the key topics at a workshop on South Africa and Africa: Prevarication at the Precipice, hosted by the Department of Political Studies and Governance at the University of the Free State (UFS). 

The two-day workshop is an annual collaborative discussion platform between the UFS, chaired by Prof Hussein Solomon, the Southern African Centre for Collaboration on Peace and Security, and the Osaka School of International Public Policy

The workshop opened with Prof Francis Petersen, the UFS Rector and Vice-Chancellor who delivered his message from the perspective of higher education. 

He spoke about the importance of universities in South Africa being able to produce graduates who will become active citizens. 

Graduates should fulfill their role in society 

“Universities should be the place where we should educate and engage to let our students and graduates know what society should look like. If we don’t do that transformative thinking among our graduates we are going to perpetuate what society is,” Prof Petersen said. 

“I hope this conference won’t just debate the issues because we already know the answers. I hope this workshop will say what we need to do as active citizens to ensure that we start new building steps. International engagement is also important. As is our engagement with the continent.” 

Helen Zille on the State of South Africa 

Helen Zille, Chairperson of the DA Federal Council presented a talk on the State of South Africa in which she tabled three variables she believes can save the country from the precipice. “There should be three variables which can make a democracy work; a separate state (not a party-ruled state), the rule of law and a culture of accountability,” Zille said. 

Zille tabled the concept of an enclaved state a state which operates independently from party control. “There are increasingly isolated states in SA which are being pushed out of good governance and service delivery. An example of an enclave that functions well is the “justice enclave (Supreme Court of Appeal) in Bloemfontein”. 

She reiterated the importance of active citizenship. However she added that people who are active citizens are usually not the ones elected to office.

The role of active citizenship and the state of the country cannot be discussed in isolation from the state of the ruling ANC and the official opposition, the DA. Prof Dirk Kotze from the Department of Political Studies at Unisa, and Bonolo Selebano, Netwerk 24 political journalist, gave a glimpse into the status of Luthuli House (ANC headquarters in Johannesburg), and the DA. 

“ANC party politics are not unique. They are following a global trend. However, the credibility of the ANC is a big issue,” said Prof Kotze. In the political arena globally, political parties are redefining themselves and it is important for the ANC to figure out where it finds itself. Selebano wasn’t too optimistic about the DA either, saying the party should return to its liberation ideals.

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.
