2023 UFS Thought-Leader Webinar Series

The University of the Free State (UFS) is pleased to present a panel discussion titled, Student protest action, politics, and higher education, which is part of the 2023 Thought-Leader Webinar Series. Join Prof Adam Habib and Dr Max Price for a discussion about their respective experiences in leadership positions during the #RhodesMustFall and #FeesMustFall student protest movements, the lessons learnt during these tumultuous times, and how these events continue to influence the current landscape in the higher education sector in South Africa and further afield. The discussion will reflect on their recent books Rebels and Rage: Reflecting on #FeesMustFall, and Statues and Storms, and will be facilitated by Prof Francis Petersen, the Vice-Chancellor and Principal of the UFS.


Date:   Tuesday 21 November 2023

Prof Adam Habib

Prof Adam Habib is an academic, researcher, activist, administrator, and well-known public intellectual. A Professor of Political Science, Prof Habib has more than 30 years of academic, research, and administration expertise, spanning five universities and multiple local and international institutions.

Prior to his appointment as Director of SOAS, he was Vice-Chancellor and Principal of the University of the Witwatersrand (Wits) in Johannesburg, South Africa between 2013 and 2020. He has also served as Deputy Vice-Chancellor of Research at the University of Johannesburg, Executive Director of Democracy and Governance at the Human Sciences Research Council, and as Director of the Centre for Civil Society and Professor of Development at the University of KwaZulu-Natal. He is widely published, including his two well-received monographs, South Africa's Suspended Revolution: Hopes and Prospects and Rebels and Rage: Reflecting on #FeesMustFall.

Prof Habib’s academic contributions resulted in his election to the American Academy of Arts and Sciences, in addition to serving as a fellow of both the African Academy of Sciences and the Academy of Science of South Africa. He also serves on the Council of the United Nations University.

 

Dr Max Price

Dr Max Price was appointed Vice-Chancellor of the University of Cape Town in July 2008, completing his ten-year term in June 2018. During the first seven years of his term, UCT experienced growth and success in research and teaching, as well as global recognition. This continued during the last three years but was overshadowed by the Rhodes Must Fall and Fees Must Fall protests during 2015 to 2017. Dr Price led the university through these storms and back to safe harbour in 2018.

Dr Price studied Medicine at the University of the Witwatersrand (Wits), during which time he became deeply involved in student politics, becoming SRC president a year after the Soweto uprising. He subsequently did a PPE degree at Oxford as a Rhodes Scholar. Following clinical work in academic and rural hospitals in South Africa, he gained a master’s degree in Community Health at the London School of Hygiene and Tropical Medicine, and then worked as an academic in the areas of health policy and economics, rural health services, and health science education.

He was dean of the Faculty of Health Sciences at Wits for ten years. He now consults in public health, higher education, strategic leadership, and advises foundations on grant making. He is currently a scholar in residence at the Atlantic Institute. He is the author of Statues and Storms: Leading through change, published in 2023.

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.
