Samantha Durrant
Samantha Durrant, the first violinist and Artistic Leader of the Odeion String Quartet, appointed since May 2024.

In the world of music, certain instruments resonate not just with sound, but with profound emotion and history. For Samantha Durrant, her journey with the violin began at the tender age of seven, inspired by the heartfelt story of Music of the Heart. This film, coupled with her exposure to the harmonious symphonies of the KwaZulu-Natal Philharmonic Orchestra, planted seeds that grew into a lifelong devotion to the violin and classical music.

Now, as part of the Odeion String Quartet – the only quartet in residence at a South African university – Durrant stands at the forefront of a mission that transcends performance. She sees her role not only as a performer, but as a steward of South Africa’s string-playing legacy. Her vision is bold yet grounded: to make the Odeion String Quartet the centrepiece of string training and performance in the country.

Reflecting on her journey, Durrant emphasises the critical role of mentorship, exposure, and perseverance. "There wasn’t one pivotal moment in my career," she shares. "It was the culmination of experiences with colleagues, mentors, and friends, all encouraging me to push my boundaries."

The Odeion String Quartet is bridging South African talent with global excellence, performing works by masters such as Haydn and Beethoven while celebrating contemporary compositions, including those from South Africa's rich tapestry of composers. For Durrant, the opportunity to collaborate with living composers is an unparalleled gift, offering insights into their inspirations and musical intentions.

Education and community are at the heart of the quartet's mission. Through school concerts, youth orchestra engagements, and performances at prestigious events such as the Vice-Chancellor’s Concert and the Rector’s Farewell, the quartet inspires audiences of all ages. "Youth orchestras represent unity," Durrant notes. "They bring people together, showcasing our shared humanity."

To those stepping into the challenging world of music, Durrant offers sage advice: "Be patient with yourself. Understand that this field is not easy, but the journey of self-discovery it offers is unparalleled."

With a packed performance calendar and ambitious goals for the quartet’s future, Durrant remains hopeful about music's place in society. "Music has the power to heal, inspire, and unite," she says. "In these challenging times, it is balm for the soul – an essential part of our humanity."

As the Odeion String Quartet continues its journey, its melodies remind us of the transformative power of music, resonating with hope and possibility across generations.

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.
