Dr Mutshidzi Mulondo, an academic in the Division of Public Health within the Faculty of Health Sciences at the University of the Free State (UFS), will make history when she becomes the first academic from the institution to be inaugurated into the Global Young Academy (GYA).

Dr Mulondo is one of two South Africans that are part of the 2025 cohort of incoming members who will be inaugurated to the sought-after prestigious Academy in Hyderabad, India. The other South African is Dr Mbuzeleni Hlongwa, a Senior Research Specialist at the Human Sciences Research Council.

The Global Young Academy is a network institution of the United Nations Scientific Advisory Board which allows young scientists from around the world to collaborate on research, set the global agenda, and contribute to global policies. The GYA develops, connects and mobilises young talent from six continents, and empowers young researchers to lead international, interdisciplinary and intergenerational dialogue and contribute to societal challenges. The GYA aims to elevate the voice of young scientists in evidence-informed and inclusive global, regional and national decision making.

The membership is comprised of passionate young scientists, typically who obtained their PhD degrees three to 10 years earlier, are between 30 to 40 years of age, and in the early stages of their independent academic careers. Members are selected for their scientific excellence and commitment to engage with society, and serve five-year terms.

 

Global Young Academy

“I feel honoured to be selected. The selection further cements the ingenuity of young African scientists and our ability to shape the global agenda. It allows us to envision a future together which leans towards empathy, kindness and unity,” said Dr Mulondo.

The Academy hopes to bridge the gap between established and new academics as well the gap between academics from the Global North and Global South. Further positioning academics from the south for interdisciplinary collaboration and publication in high impact journals to address complex and emerging challenges such as public health issues. The Academy selects young academics who display contribution to research, dedication to serving society and the ability to make an impact on the Academy’s community.

 

Aspirations in the academy

The recognition is testament that Africa is still producing globally competitive academics. This achievement is even better as it comes during the G20 presidency when Africa is showing what the developing world can produce. Coincidentally, Dr Mulondo, was one of the invited speakers at the G20 Research & Innovation Working Group, joining other selected young academics.

According to Dr Mulondo, who won the Zenith Global Health Award under the category ‘Mental Health and Well-being’ last year and was first runner-up in the category Emerging Leader at the South African Health Excellence Award. Academics from Africa have a responsibility to contribute to the development of the continent through evidence-based advice and solutions to policymakers. This membership allows young academics to stay in touch with global scientific trends and shifts in order to be better informed about resolving some of humanity’s most pressing crises.

She hopes to continue to advance public health strategies that prioritise mental health and health equity. With geopolitical complexities, climate changes and technological advancements shaping our future, the Academy allows for voices from the Global South to contribute to global policies and influence global policy decisions. “As a mentor and supervisor of master’s and PhD students in Public Health, I hope to contribute to ushering in a new generation of well-rounded public health researchers who are societally engaged.”

Prof Anthea Rhoda, UFS Deputy Vice-Chancellor: Academic, congratulated Dr Mulondo, saying the UFS is extremely proud of her. “Being selected as one of two South African scholars to the Global Young Academy demonstrates her dedication as a public health scholar passionate about making a difference in the health and well-being of society. Well done, on this great achievement.”

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.
