Our world has changed.  The aspects that we have accepted as daily occurrences, and those that we have taken for granted, are no longer possible.  Anxiety and uncertainty have filled our lives.  After the first infections in China at the end of 2019, the Coronavirus (COVID-19) has continued to spread across the world.  The number of people infected and those who die is increasing daily, and no continent has been able to escape this pandemic.  In addition to the threat to public health, the economic and social disruption threatens the long-term livelihoods and well-being of millions.  It has been said that the rate and global spread of infection by COVID-19, and the impact it could have on a globalised financial, political, and social architecture, sets this particular pandemic apart from any other in modern times.

Not only have governments declared national emergencies and implemented lockdown policies to curb the spread of the disease, they have also taken unprecedented measures to lessen the impact on business, jobs, and the vulnerable communities in our society.   The COVID-19 outbreak has catalysed a crisis, which is questioning the confines of inherited structures that have perhaps lost their intellectual edge and global mandate.

How are universities as global institutions of higher learning managing COVID-19?  

Universities are complex institutions.  I will not attempt to describe the role and purpose of the modern university here – safe to say that the views of John Henry Newman (The Idea of a University) and Wilhelm von Humboldt (his recommended views led to the creation of the University of Berlin) dominated Western thinking about the functions of a university.  Sir Colin Lucas, former Vice-Chancellor of the University of Oxford, remarked “…(universities) are seen as vital sources of new knowledge and innovative thinking, as providers of skilled personnel and credible credentials, as contributors to innovation, as attractors of international talent and business investment into regions, as agents of social justice, and as contributors to social and cultural vitality”.  There is no doubt that universities, through their intellectual knowledge base, can add (and they do) enormously to the science of COVID-19, whether it is developing a new vaccine, modelling, and forecasting skills to understand the spread of the virus in specific regions or innovative methods for supplemental oxygen delivery.  The role played by universities in this context is vast and critical.  

Universities serve a large variety of functions in the delivery of the academic project, which involves teaching, learning, and research to maintain, manage, and develop the physical and digital infrastructure – the engagement with external stakeholders (to foster societal impact) such as alumni, schools, governments, industry, the private sector, commerce, donors, and philanthropic foundations. Many universities are training medical doctors and other healthcare professionals, engaging with academic hospitals and placing them at the forefront of the healthcare system – a very complex organisation to manage, even in times with no crises!

Many universities have disaster management committees that were rapidly activated during COVID-19 to prepare plans for the unexpected.  This pandemic, due to the extent of unfamiliarity and uncertainty thereof, can challenge these efforts and expose limitations in such plans.

It is important that universities have a framework approach of effective coordination, integration, and decision making that is centrally located but can act fast.  Although universities are not the same, there is a common drive for the health, well-being, and safety of staff and students. Typically, such a framework could converge in an Executive Centre (decision-making) or nerve centre, which should preferably be convened by the Vice-Chancellor, and include expertise in areas of scenario planning, project management, science (in this particular case it would be virologists and/or epidemiologists), communication, and institutional culture.  In order for the Executive Centre (EC) to be effective and fast-moving (with urgency and robust thinking), it should be organised around multi-disciplinary task teams, each with key responsibilities:

Teaching and Learning –with the suspension of classes (specifically in countries where there is a lockdown), alternative methods need to be utilised to deliver the academic project, and most universities have moved online (although not online in the purest form, rather emergency remote learning – turning a course virtual in a short period of time, and more importantly, doing it well, is nearly impossible for faculty members accustomed to lecturing in front of students). Based on the extent of the particular lockdown period, academic calendars need to be adjusted. Low-technology approaches to teaching and learning should be developed that are sensitive to the challenges of connectivity, bandwidth, and the type of devices that students use, realising the deep socio-economic inequalities and digital divide in our society. It is critically important to stay in touch with the students, and to provide online assistance with respect to counselling and mental health.

Research – focusing on how experimental research will be conducted during lockdown, how research contracts will be managed during this period and beyond, and whether research funding will be redirected or terminated;

Science – to understand epidemiological developments, verified information on COVID-19 (against the background of fake news);

Operations – mainly focusing on environmental hygiene and the business continuation of the physical and digital plant;

Staff – working remotely, essential services (as defined by government), and crucial university functions, constantly staying in touch with the staff, especially regarding their state of mind (mental health) due to social isolation;  

Students – with a focus on responsible student integration on the re-opening of the campus, where the principle of social distancing need to be adhered to;

Financial and Legal – responsible for financial scenario planning, short-term cash management and risk management, and mitigation; and

Communications – need to be centralised to ensure that it is consistent, correct, rapid and that it takes into account institutional culture when communicating – crises create anxiety, but keeping people informed helps reduce stress.

It is advisable to include a student voice or student input in the Teaching and Learning Task Team, as the living experience of students can thus be captured more accurately, which can enhance strategies.

It is clear that the world will operate differently post-COVID-19 than before the pandemic (‘new normal’); the EC will become the source of scenario planning on how universities will have to ‘re-imagine’ themselves post this pandemic.  It is thus critical to ensure that data, experiences (although a health crisis, an economic, and perhaps a social crisis – an opportunity as a thought experiment), ideas and new networks are captured with a strategic intent and reflection within the EC. Not only has this crisis questioned the neo-liberal economies that traditionally limit government intervention and prioritise market interests, it also asked universities to think differently about their models of teaching, research, and internationalisation, and how co-creation across boundaries and different sectors of the economy need to be imagined.

A crisis is never straightforward to manage, but an Executive Centre-type structure could not only assist universities during this period, but can add valuable strategies to position universities after such a crisis.

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.
