World Mental Health Day
The UFS community, in partnership with various stakeholders, commemorated World Mental Health Day on 10 October 2022.

About 400 million people globally suffer from mental or neurological disorders and psychosocial problems. Mental disorders, much like physical ones, differ in severity. The Department of Health distinguishes between transient (such as an acute stress disorder), periodic (such as bipolar disorder, characterised by periods of exaggerated elation followed by periods of depression), and long-lasting and progressive (such as Alzheimer’s disease) disorders.

Mental health issues such as depression, anxiety, substance abuse, and job stress are the most common conditions. It is not only the individuals suffering from these problems who are affected, but also their families, co-workers, and the broader community. An interplay between biological, psychological, social, and environmental factors results in mental health conditions.

Mobilising efforts in support of mental health
Internationally, the month of October has been declared Mental Health Awareness Month, with 10 October being the day on which Mental Health Day is observed. The objective is to educate the public about mental health and to reduce the stigma that people with mental illness are often subjected to. To mark the day, the University of the Free State (UFS) Student Counselling and Development (SCD) Office, KovsieHealth, and the student mental health advocacy organisation, Next Chapter, held an activation at the Thakaneng Bridge on the Bloemfontein Campus. This followed a silent walk from the campus’ main gate to the bridge.

Chairperson of Next Chapter, Lehlogonolo Sebjetseba, emphasised the significance of commemorating Mental Health Day. “The importance of observing this day is to continue raising awareness about mental health and to further reduce the stigma around mental health. We did this by introducing students to different psychosocial support organisations such as Alnisa Continua, Panda, the Befrienders, and more. These organisations cater specifically for students’ mental well-being,” said the second-year Industrial Psychology student.

Raise awareness of mental health issues
On 12 October 2022, the Division of Organisational Development and Employee Well-Being, together with the Department of Human Resources (HR), presented a Mental Health talk by award-winning journalist and author, Marion Scher, on the Bloemfontein Campus. The talk touched on preventive mental health interventions, breaking the silence around mental health issues, and guidelines on how to provide support to those affected by mental health problems.

Scher further explained bipolar disorder and schizophrenia, as well as the difference between a bad day and clinical depression. Guidance was provided on avenues to explore when seeking mental health assistance, and advice was offered on what to do if you think someone is having suicidal ideation. In addition, the division has made available the Mental Health Awareness Month Toolkit, which employees can access for free online.

Mental health is a global priority
The overall objective of World Mental Health Day is to raise awareness of mental health issues around the world. This year’s national theme is ‘Mental Health and Well-being for All: Promoting Mental Health in Physical and Virtual Spaces’, which is based on the global theme: ‘Making Mental Health and Well-Being for All a Global Priority’. This is in line with Sustainable Development Goal number three, which focuses on good health and well-being.

SCD and HR will continue to host events throughout the year that encourage students and staff to protect and improve their mental health. These are some of the upcoming events:

Health Survival Guide webinar (students):
Date: 21 October 2022
Time: 10:00
Venue: Blackboard

Self-care webinar (students):
Date: 1 November 2022
Time: 12:00-14:00
Venue: Blackboard

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.
