Academic Advising Office 2024

The Academic Advising Office in the Centre for Teaching and Learning (CTL) on the University of the Free State (UFS) Qwaqwa Campus hosted an Academic Advising activation under the theme: Unombuzo? Tloho o tlo botsa adviser ya hao for undergraduate students on 12 July 2024 in preparation for the second semester.

The event was aimed at assisting students to reach their full potential and strive for academic success. It marked the starting point for students to prepare for the second semester of their academic year in stride.

Increase student use of academic advising services

CTL aims to advance evidence-based innovation that promotes excellence in learning and teaching for student access with success.

The objective of the activation was to increase the visibility of academic advising on the Qwaqwa Campus. The goal was also to increase students’ use of the various general academic advising services. The Advising Office noticed that not many students attended general advising sessions in the last semester, which inspired the activation as well as the introduction of the newly appointed transition advisers.

The Advising Office urges students to attend time management and study strategy sessions. The office also assists students in collaboration with the faculties, Student Counselling and Development, residences, the No Student Hungry office, Career Services, and other stakeholders at the university.

Success of the event

The event was a great success, as 120 students showed up and had the opportunity to speak face to face to the advisers. Alongside the advisers, a curriculum adviser from the Faculty of The Humanities, representatives from University Estates, the CTL office, and Transition Development and Success were in attendance.

The advising team was able to introduce advising to students, listen to their concerns, and provide short general advising opportunities. Students were treated to some goodies at the event and were given a chance to enter a competition through a survey, which will result in four lucky students winning exciting prizes.  Students had a great time, taking pictures, videos, and dancing to the music at the venue.

If students missed this opportunity, there will be more opportunities to meet the team through advising pop-ups:

• 26 July 2024 – Dining Hall
• 2 August 2024 – UFS Taxi Rank
• 16 August – Outside Fulufhelo Residence

• 13 September – Notice boards near the Intsika Building

Where to find your advisers

• Intsika Building, Ground Floor, Offices: 0030, 0043, 0044

• Email address: AdvisingQQ@ufs.ac.za

The activation’s objectives were to

• increase the visibility of academic advising on campus;
• increase student use of academic advising services;
• make students aware of the services offered by Academic Advising; and
• share different ways with students to connect with the advising team and how to set up appointments with their advisers.

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.
