During the Faculty of Education ceremony, Louzanne Coetzee, a blind UFS alumna and speaker, shared her remarkable journey. From her days as a high school learner to becoming a student, she highlighted her challenges and how she overcame them.

The April graduations at the University of the Free State (UFS) were a remarkable celebration of diversity and inclusivity, with 44 graduates with learning difficulties, visual, mobility, or hearing impairments honoured for their achievements.

Despite facing unique challenges throughout their academic journeys, these resilient students triumphed over adversity to earn their degrees, inspiring their peers and educators alike – all with the assistance of the Centre for Universal Access and Disability Support (CUADS) within the Division of Student Affairs.

Words of advice from the recent graduates

Nkosingiphile Nyanale, who is blind, recently graduated with a Bachelor of Laws (LLB) degree. He emphasised the importance of mutual understanding between students and educators as a way of helping students with disabilities to overcome the extra hurdles they face. “One of the most challenging parts of my journey was reaching a common understanding with some facilitators on how I could be reasonably accommodated in class,” Nyanale said. “Some lecturers would deny themselves the opportunity to understand the challenges of students with visual impairments and viewed my requests as a way of seeking an easy pass. So, peers and lecturers understanding various impairments helped shape my journey.

Sthembiso Dlamini, a BSc Mathematics and Mathematical Statistics graduate who lives with dysgraphia, a condition that creates challenges related to handwriting, spelling, and organising thoughts on paper, said, “In my third year, I struggled to focus during high-stress exams. I willingly sacrificed much of my leisure time to tackle this obstacle head-on. I committed myself to honing my learning methods and enhancing my time-management abilities.” 

Relebohile Moloi, a nursing graduate, thanked CUADS for its help, and said greater awareness of the centre and its services could help more students. “They should assess students regularly for impairments, because sometimes people don’t know they have an impairment. CUADS should visit each faculty to give information on who they are and what they offer.”

The speaker

Louzanne Coetzee, a blind UFS alumna, shared her story during the last graduation session of the season on 20 April. “After matriculating at the Pioneer School in Worcester [Western Cape], where it was a protected environment, I did not know what to expect from the UFS. However, the UFS gave me a conducive environment by allowing my guide dog, Isabel, into the residences. I was the first person to be allowed such.” [Listen to her full speech here.]

Inclusive environment

Martie Miranda, Deputy Director at CUADS, said she’s proud of the graduates, as they embody the UFS’s dedication to an inclusive environment that caters to all its students, in line with the university’s Vision 130, which aims to foster academic excellence in a diverse and equitable environment. “In celebrating our graduates, we honour not just their achievements but the enduring commitment of CUADS staff and the university to foster an inclusive environment where every student's journey is valued and supported."

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.
