Prof Wynand Goosen, Professor and Lead for One Health in the Department of Microbiology and Biochemistry at the University of the Free State was nominated in the TW Kambule-NSTF Award: Researcher category of the 2024/25 NSTF-South32 Awards.

Being nominated for a ‘Science Oscar’ is exciting and validates nominees’ efforts, particularly in a field as challenging and essential as infectious diseases, for which they are recognised at the highest level. 

This is according to Prof Wynand Goosen, Professor and Lead for One Health in the Department of Microbiology and Biochemistry at the University of the Free State (UFS). He was nominated in the TW Kambule-NSTF Award: Researcher category of the 2024/25 NSTF-South32 Awards for his landmark discovery of Mycobacterium bovis infection in humans in South Africa – the first confirmed cases in the country. 

Prof Goosen, who previously won the NSTF-South32 Emerging Researcher Award, says the nomination is a powerful affirmation of the impact that focused, interdisciplinary research can have. It reflects not only his personal commitment but also the dedication of a talented and hard-working team. “I am honoured and humbled to be nominated. It is also a testament to the support and vision of UFS, particularly as we position ourselves as leaders in One Health research in South Africa,” he says. 

 

Focus of research 

He was nominated by Prof Vasu Reddy, UFS Deputy Vice-Chancellor: Research and Internationalisation, and Prof Paul Oberholster, Dean for the Faculty of Natural and Agricultural Sciences (NAS) at the UFS, and Prof Nico Gey van Pittius and Prof Elmi Muller from Stellenbosch University (US). The NSTF Awards, known as the ‘Science Oscars’of SA, honour, reward, celebrate, profile and promote outstanding contributions to science, engineering and technology (SET) and innovation in South Africa.

“The nomination,” Prof Goosen continues, “recognises our work in the field of zoonotic tuberculosis (TB) and other emerging infectious diseases at the human-animal-environment interface. Our research focuses on the molecular detection and characterisation of pathogenic mycobacteria in wildlife, livestock, and human populations, with the aim of informing better surveillance, diagnostics, and control strategies — particularly in high-risk ecosystems. This includes novel applications in wildlife TB surveillance and understanding the transmission dynamics between animals and people.”

 

Establishing a Kovsie One Health Research Unit

This research is critically important as South Africa continues to face a high burden of tuberculosis, including zoonotic TB, which often goes under-detected in rural and wildlife-rich areas. Understanding how these pathogens circulate between humans, animals, and the environment, explains Prof Goosen, is essential for effective disease control and to mitigate future pandemics. This work directly supports national health priorities, informs policy, and contributes to global strategies for One Health.

Prof Goosen and the team are in the process of laying the groundwork for the establishment of a Kovsie One Health Research Unit, which will serve as a collaborative platform for research spanning human, animal, and environmental health. One of their key projects involves expanding TB and AMR surveillance in wildlife-livestock-human interfaces, using cutting-edge diagnostics and genomic tools. They are also initiating partnerships with industry and international institutions to address emerging zoonoses and environmental pathogens in a transdisciplinary manner.

Sunflowers are satellite dishes for sunshine, or are they?
2016-07-20

Eighty-six percent of South Africa’s
sunflowers are produced in the
Free State and North West provinces.

Helen Mirren, the English actress, said “the sunflower is like a satellite dish for sunshine”. However, researchers at the University of the Free State (UFS) have found that too much of this sunshine could have a negative effect on the growth of sunflowers, which are a major source of oil in South Africa.

According to Dr Gert Ceronio from the Department of Soil, Crop, and Climate Sciences at the UFS, extremely high soil temperatures play a definite role in the sprouting of sunflower seedlings. Together with Lize Henning, professional officer in the department, and Dr André Nel from the Agricultural Research Council, he is doing research on biotic and abiotic factors that could have an impact on sunflowers.

Impact of high temperatures on sunflower production

The Free State and North West provinces, which produce 86% of South Africa’s sunflowers, are afflicted especially by high summer temperatures that lead to extremely high soil temperatures.

Dr Ceronio says: “Although sunflower seeds are able to germinate at temperatures from as low as 4°C to as high as 41°C, soil temperatures of 35°C and higher could have a negative effect on the vegetative faculty of sunflower seedlings, and could have an adverse effect on the percentage of sunflowers that germinate. From the end of November until mid-January, this is a common phenomenon in the sandy soil of the Free State and North West provinces. Soil temperatures can easily exceed the critical temperature of 43°C, which can lead to poor germination and even the replanting of sunflowers.”

Since temperature have a huge impact not only on the germination of sunflower seeds, but also on the vegetative faculty and sprouting of sunflower seedlings, Dr Ceronio suggests that sunflowers should be planted in soil with soil temperatures of 22 to 30°C. Planting is usually done in October and early November. Unfortunately, this is not always possible, as soil moisture is not optimal for growth. Farmers are then compelled to plant sunflowers later.

Impact of herbicides on sunflower growth

“High soil temperatures, combined with the herbicide sensitivity of some cultivars, could lead to the poor development of seedlings," says Dr Ceronio.

The use of herbicides, such as ALACHLOR, for the control of weeds in sunflowers is common practice in sunflower production. It has already been determined that ALACHLOR could still have a damaging effect on the seedlings of some cultivars during germination and sprouting, even at recommended application dosages.

“The purpose of the continued research is to establish the sensitivity of sunflower cultivars to ALACHLOR when exposed to high soil temperatures,” says Dr Ceronio.
