In light of the ongoing violence against women, and recent surge in femicide in South Africa, the University of the Free State (UFS) recommits itself to challenge, fight and eradicate all forms of gender-based violence on its campus and in the country.

The recent rape and murder of 19-year-old Media and Film Studies student at the University of Cape Town (UCT), Uyinene Mrwetyana, and the murder of University of the Western Cape (UWC) student, Jesse Hess, are painful reminders of the pervasive nature of misogyny and patriarchal violence that impedes the freedom of women/womxn in South Africa. The UFS stands in solidarity with UCT and UWC, and all other South African universities that are currently steeped in this national crisis pertaining to gender-based violence.

The UFS perceives this as an enduring manifestation of patriarchy that results in women’s/womxn’s subordination, inequality, and violation of bodily integrity. These horrific events underscore the extent to which attempts to address women’s/womxn’s inequality and gender-based violence nationally, and more pertinently at universities, have failed. Recent discussions have underscored the issue of ‘belonging’ as a concern in Higher Education contexts. Belonging is often couched in the language of ‘access’ and ‘transformation’. However, these terms often provide limited substantive change for students who experience a sense of marginalisation and alienation at South African universities. Decolonisation discourse challenges the nature of hegemonic knowledge production that excludes voices of alterity.

Epistemic violence is central to decolonisation discourse referring to the nature of hegemonic knowledge production that excludes voices of alterity. The extent to which knowledge production manifests in universities is, however, not only white and Western, but also male and masculine. South African universities are therefore confronted again with the urgency of recognising and responding to the issue of women’s/womxn’s subordination, with specific emphasis on their safety and freedom.

The UFS is committed to creating a university space where all our students feel that they belong, by broadening current epistemologies and including women’s/womxn’s voices and lived experiences. More pertinently and in a practical manner, curriculum change should include diverse intellectual perspectives and incorporate an ethics of care in teaching practices. The UFS acknowledges that more must be done as a space of higher learning to investigate the causes that underlie the continuance of sexual violence against women/womxn.

On Friday 6 September 2019, the UFS held a day of mourning, standing in solidarity with other universities in their attempt to respond to the present crisis. In mourning Uyinene and Jesse’s death and all other victims and survivors of gender-based violence, the university will critically self-reflect on the multi-layered demand for transformation and consciousness needed for deep change.

The UFS calls on the Department of Higher Education, civil society, the business sector and all others to actively contribute to efforts that will eradicate gender violence. As the UFS, we call specifically on the City of Bloemfontein, the mayor, members of local government, South Africa Police Service and all inhabitants to assist us in making the city safe for all.

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.
