S4F2024
The Science-for-the-Future (S4F) unit in the Faculty of Education hosted a summit on 13 September 2024. The event, which was held on the University of the Free State Bloemfontein Campus, was well attended by nearly 300 guests from across the country.

Teachers from across the country and representatives of nine other universities recently gathered at the University of the Free State (UFS) to celebrate the achievements of the S4F Teacher Professional Development programmes as well as the successful collaboration between the UFS and other universities in this regard.

The Science-for-the-Future (S4F) unit in the Faculty of Education hosted a summit in the Centenary Complex on the Bloemfontein Campus on 13 September 2024. The acting Vice-Chancellor and Principal of the UFS, Prof Anthea Rhoda, delivered the keynote address at the summit. Representatives from the South African National Roads Agency (SANRAL) – the official funder of the Science for the Future initiative – were also present, along with about 300 attendees, representing teachers, participating universities, representatives from the Department of Basic Education, and other stakeholders.

In her welcoming address, Prof Matseliso Mokhele Makgalwa, Vice-Dean of the Faculty of Education, said the event focuses, among others, on fostering collaboration and innovation across academic and professional communities. She later highlighted the fact that the project implementation period of three years makes provision for continued visits to the participating schools to sustain the continuity over time.

Dr Cobus van Breda, Programme Director of S4F and Project Manager of the Universities Collaboration initiative, elaborated on the rationale of the project as well as the collaboration with nine other universities. He stated, “We know from research that there are many factors that prevent learners, especially in rural areas in South Africa, from excelling in Mathematics and Science. These include subject content knowledge, lack of teaching resources at school and at home, language of learning and teaching that differs from home language, along with a lack of parental involvement, among others.” He said the project aims to address these rampant challenges by not only empowering teachers with the necessary teaching skills and content knowledge, but also providing classroom resources to benefit learners and adding a parental involvement component to the project. 

To scale the project benefits for the rest of the country, the UFS has partnered with nine other universities; collectively, more than one hundred thousand project participants (teachers, learners, and parents) could be impacted during 2024. The collaborating universities are Nelson Mandela University, the Walter Sisulu University, the University of Limpopo, the University of KwaZulu-Natal, the University of Mpumalanga, Sol Plaatje University, the University of Venda, Stellenbosch University, and Nort-West University.

Representatives from the Department of Basic Education and other institutions were also given the opportunity to highlight the impact of the initiative in their respective institutions. Maki Molale, Senior Education Specialist  from the Free State Department of Basic Education, reflected on the contribution of the project and said, “In the Department of Education we report on these key areas: teacher development, direct learner support, parental involvement, the utilisation of resources and partnerships … they are all addressed in this project.” She thanked the University of the Free State and the funder, SANRAL. Dr Glynnis Daries from Sol Plaatje University spoke on behalf of the collaborating universities and explained from an academic perspective to attendees how the project implementation strategy of S4F relates to Bronfenbrenner’s bioecological theory of human development and how the respective project components showcase the five levels of this theory.

During the keynote address, Prof Rhoda emphasised the importance of Mathematics skills, teaching children the capacity to solve problems and how it is extremely important to be analytical in one’s approach to resolving complexities and to work through problems in a methodical and logical manner. In the end, if one does this, no challenge is insurmountable. She commended the teachers present for fulfilling a vital task and pointed out the heavy responsibility on their shoulders. In this regard, she said, “As the UFS, and through the Science for the Future project, we are proud to support you in your work. The project is a vehicle through which we fulfil the central goals of the UFS, which are to impact the community in a positive way, and to instil a culture of excellence in a caring environment. We will continue to support you in your work and do all that we can to make your work more fulfilling and impactful – this is the promise of the UFS to our partners through this project.”

In acknowledging the contribution of the respective collaborating universities, Prof Rhoda emphasised that partnerships and collaborations are not easy to build, and most importantly, to maintain … “but what I’m hearing through these engagements today is that these partnerships are not just being maintained, they are expanded … the collaboration impacted the different institutions as well as, most importantly, the communities, close to and around them”. She alluded to the fact that universities’ roles are not just to retain and accept students, but universities have an important role in being the anchor within the society and communities in which they find themselves. According to her, the contribution of SANRAL and other project funders thus extends far beyond teachers’ professional development and community empowerment, it contributes towards assisting universities in engaged scholarship activities.

In reflecting on the parental involvement component of the programme, Themba Mhambi – Chairperson of the SANRAL Board – said that apart from being a maths and science project, and a project that is developmental, that is nation building, “… it becomes a kind of template for perhaps how our education system needs to be re-constructed … reclaiming the old times when parents and teachers worked together with the child in the centre”.

CONTROL OF INFECTIOUS AVIAN DISEASES – LESSONS FOR MAN?

“Many of the lessons learnt in disease control in poultry will have application on human medicine,” said Prof Robert Bragg, lecturer at the University of the Free State’s (UFS) Department of Microbial, Biochemical and Food Biotechnology during his inaugural lecture.

Prof Bragg said the development of vaccines remains the main stay of disease control in humans as well as in avian species.  Disease control can not rely on vaccination alone and other disease-control options must be examined.  

“With the increasing problems of antibiotic resistance, the use of disinfection and bio security are becoming more important,” he said.

“Avian influenza (AI) is an example of a disease which can spread from birds to humans.  Hopefully this virus will not develop human to human transmission,” said Prof Bragg.

According to Prof Bragg, South Africa is not on the migration route of water birds, which are the main transmitters of AI.  “This makes South Africa one of the countries less likely to get the disease,” he said.

If the AI virus does develop human to human transmission, it could make the 1918 flu pandemic pale into insignificance.  During the 1918 flu pandemic, the virus had a mortality rate of only 3%, yet more than 50 million people died.

Although the AI virus has not developed human-to-human transmission, all human cases have been related to direct contact with infected birds. The mortality rate in humans who have contracted this virus is 67%.

“Apart from the obvious fears for the human population, this virus is a very serious poultry pathogen and can cause 100% mortality in poultry populations.  Poultry meat and egg production is the staple protein source in most countries around the world. The virus is currently devastating the poultry industry world-wide,” said Prof Bragg.

Prof Bragg’s research activities on avian diseases started off with the investigation of diseases in poultry.  “The average life cycle of a broiler chicken is 42 days.  After this short time, they are slaughtered.  As a result of the short generation time in poultry, one can observe changes in microbial populations as a result of the use of vaccines, antibiotics and disinfectants,” said Prof Bragg.   

“Much of my research effort has been directed towards the control of infectious coryza in layers, which is caused by the bacterium Avibacterium paragallinarum.  This disease is a type of sinusitis in the layer chickens and can cause a drop in egg product of up to 40%,” said Prof Bragg.

The vaccines used around the world in an attempt to control this disease are all inactivated vaccines. One of the most important points is the selection of the correct strains of the bacterium to use in the vaccine.

Prof Bragg established that in South Africa, there are four different serovars of the bacterium and one of these, the serovar C-3 strain, was believed to be unique to Southern Africa. He also recently discovered this serovar for the first time in Israel, thus indicating that this serovar might have a wider distribution than originally believed.

Vaccines used in this country did not contain this serovar.  Prof Bragg established that the long term use of vaccines not containing the local South African strain resulted in a shift in the population distribution of the pathogen.

Prof Bragg’s research activities also include disease control in parrots and pigeons.   “One of the main research projects in my group is on the disease in parrots caused by the circovirus Beak and Feather Disease virus. This virus causes serious problems in the parrot breeding industry in this country. This virus is also threatening the highly endangered and endemic Cape Parrot,” said Prof Bragg.

Prof Bragg’s research group is currently working on the development of a DNA vaccine which will assist in the control of the disease, not only in the parrot breeding industry, but also to help the highly endangered Cape Parrot in its battle for survival.

“Not all of our research efforts are directed towards infectious coryza or the Beak and Feather Disease virus.  One of my Masters students is currently investigating the cell receptors involved in the binding of Newcastle Disease virus to cancerous cells and normal cells of humans. This work will also eventually lead to a possible treatment of cancer in humans and will assist with the development of a recombinant vaccine for Newcastle disease virus,” said Prof Bragg.

We are also currently investigating an “unknown” virus which causes disease problems in poultry in the Western Cape,” said Prof Bragg.
 
“Although disinfection has been extensively used in the poultry industry, it has only been done at the pre-placement stage. In other words, disinfectants are used before the birds are placed into the house. Once the birds are placed, all use of disinfectants stops,” said Prof Bragg.

“Disinfection and bio security can be seen as the ‘Cinderella’ of disease control in poultry.  This is also true for human medicine. One just has to look at the high numbers of people who die from hospital-acquired infections to realise that disinfection is not a concept which is really clear in human health care,” said Prof Bragg.

Much research has been done in the control of diseases through vaccination and through the use of antibiotics. “These pillars of disease control are, however, starting to crumble and more effort is needed on disinfection and bio security,” said Prof Bragg.

Prof Bragg has been working in close co-operation with a chemical manufacturing company in Stellenbosch to develop a unique disinfectant which his highly effective yet not toxic to the birds.

As a result of this unique product, he has developed the continual disinfection program for use in poultry. In this program the disinfectant is used throughout the production cycle of the birds. It is also used to ensure that there is excellent pre-placement disinfection.

“The program is extensively used for the control of infectious diseases in the parrot-breeding industry in South Africa and the product has been registered in 15 countries around the world with registration in the USA in the final process,” said Prof Bragg.

“Although the problem of plasmid mediated resistance to disinfectants is starting to rear its ugly head, this has allowed for the opening of a new research field which my group will hopefully exploit in the near future,” he said.
