The new US Consul General, Vincent Spera, recently visited the UFS Bloemfontein Campus. He was hosted by the Office for International Affairs. Pictured here are Cornelius Hagenmeier, Dr Dionne van Reenen, and Vincent Spera.

Vincent Spera, the new US Consul General, paid a courtesy visit to the University of the Free State (UFS) on 16 September 2021, where he was hosted by the Office for International Affairs on the Bloemfontein Campus.

The aim of his visit was to strengthen relationships with the UFS. The university has a rich academic collaboration with US higher education institutions, as evidenced by the 313 co-authored papers published by UFS authors with collaborators at 291 institutions in the United States (US) between 2018 and 2020.

In the past eight years, close to 150 international students from the US – from postdoctoral fellows up to undergraduate level – studied at the UFS. The UFS is also home to more than 30 research fellows from the US. 

Cornelius Hagenmeier, Director of the UFS Office for International Affairs, says he would like every student to have an international experience. “I believe it is doable. Through virtual exchanges, curriculum internationalisation, and internationalisation at home, we can make this happen,” he says. 

Prof Corli Witthuhn, Vice-Rector: Research, emphasised the importance of US collaborations for the university. She appreciates the support afforded by the US Consulate for the manifold collaborative activities connecting the UFS with the US. 

A number of UFS researchers who is collaborating with the US on certain projects interacted with Spera during his visit. 

USDP Programme

According to Prof Corlia Janse van Vuuren, Head: UFS School of Health and Rehabilitation Sciences, the Faculty of Health Sciences’ biggest academic collaboration with US higher education institutions is through the University Staff Development Programme (USDP).

She says: “The USDP is an enriching journey for the group of UFS academic staff members who participate as PhD candidates in this initiative. The international connection with the University of Virginia (UVA), where mentors are assigned to most of the PhD candidates, is raising the quality of the qualification.”

This doctoral training programme supports the doctoral degree studies of a cohort of six academics from the UFS and five from the University of Venda (Univen) in the field of global health. The group of PhD candidates are from different disciplines in health sciences, including Anaesthesiology, Orthopaedics, Obstetrics and Gynaecology, as well as Occupational Therapy in the Allied Health Sciences. One of the candidates completed his studies and is working with UVA on a number of publications; the rest of the candidates will complete their studies in 2022 and 2023. 

“These doctoral candidates are also very much involved in student training as well as medical specialist training. This increases the quality of our medical specialist training in the faculty. Undergraduate student training also indirectly benefits from this initiative,” she adds.

Dr Gray Magaiza, Acting Assistant Vice-Dean and Programme Director in the Department of Sociology on the UFS Qwaqwa Campus, is in agreement about the value of the USDP programme. He himself received his PhD qualification through the programme.

“The programme opened many doors for me. It was one of the best experiences I ever had, especially the support I received in completing my studies. The quality sought by US supervisors are also quite high,” he says. 

Spera says it is wonderful to hear about the collaborations taking place. “It is through these partnerships that connections between South Africans and Americans are allowed to grow exponentially.”

“PhD development is critical, and we want to increase the number of PhD graduates, particularly staff members with PhD qualifications. We appreciate the collaboration with the US in research and capacity development, which together with internalisation are high priorities,” Hagenmeier says.

Fulbright Scholarships

Prof Lynette Jacobs, Head of Research on the UFS South Campus, acknowledged the contribution that the Fulbright programme has made to the UFS South Campus. Four years ago, the visit of one Fulbright scholar, Prof Barbara Howard from the Appalachian State University, evolved to a long-term commitment from individuals and the institution to continue working on intercultural and international projects, as well as research collaborations. 

Together with academics from Novgorod State University in Russia, Prof Jacobs and Prof Howard are collaborating on the development of virtual capacity building programmes, specifically to support internationalisation. The courses include international cross-cultural communication skills, leadership in virtual international teams, sustainable development, and using technology meaningfully in a virtual international space. 

“This is a wonderful testament to not letting ourselves get fixed to one kind of thinking. It does not always have to be the five-year PhD or two-year academic Fulbright programme, but there are all sorts of models that can make a difference,” responds Spera.

Guided by Dr Dionne van Reenen, Senior Researcher in the Unit for Institutional Change and Social Justice, Spera undertook a walking tour of the UFS Centenary Complex and the Unit for Institutional Change and Social Justice. He appreciated the information shared about the UFS transformation process, and the collaboration between the US and the unit. 

According to Mbali Moiketsi, Study Abroad coordinator, the US consulate has supported and offered guidance to UFS students and staff to pursue study abroad opportunities with the assistance of International Affairs. 

Recently, the university had two recipients of the Fulbright foreign student scholarship and has to date hosted three Fulbright visiting scholars. These recipients have contributed to the growth of the partnership and has increased relations with universities in the US. The partnership is set to continue, offering broad opportunities for the UFS staff and students.

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.
