With respiratory diseases contributing to the highest morbidity and mortality rate in children, and the vast majority of disease aetiology remaining undiagnosed in clinical settings, Dr Ayodeji Emmanuel Ogunbayo hopes his research for his PhD in Medical Virology will help to reduce mortality in children with respiratory infection.

Dr Ogunbayo, commonly known as Dr Emms by his peers, graduated on Thursday (20 April 2023) with a Doctor of Philosophy degree with specialisation in Medical Virology at the University of the Free State (UFS) Faculty of Health Sciences graduation ceremony. The title of his thesis was Metagenomics of the respiratory RNA virome of children in the Free State. His supervisor was Prof Martin Nyaga, Associate Professor in the UFS Next Generation Sequencing (UFS-NGS) and Director of the WHO Collaborating Centre (WHO CC).

“While clinical metagenomics next-generation sequencing (mNGS), which is an upcoming method, has the potential to revolutionise infection diagnosis and management in children, there is a dearth of information on its clinical applicability in Africa. This is the knowledge that guided the inception of this research,” says Dr Ogunbayo.

Project came at the right time

He commenced with his PhD in Medical Virology in 2019, which was centred on the applicability of mNGS in severe acute respiratory infection (SARI) in children and deciphering the children’s respiratory virome in health and disease, a project which was the first of its kind in Africa.

According to him, the project was conceived before the COVID-19 pandemic, however, despite the challenges encountered due to lockdown measures, the project came at the right time as it was able to address several profound effects of the pandemic such as COVID-19 on the dynamics of transmission of respiratory viruses and ultimately its effect on children’s health. During his PhD study, he published four manuscripts in highly reputable journals including the most recent one which was accepted in Journal of Medical Virology (JMV)  an impressive impact factor of 20.693.

The findings from this study included a validated and robust workflow to recover respiratory RNA viruses from clinical samples, according to the graduation programme. The established workflow was adapted to decipher children’s respiratory virome composition in health and disease, with a degree of heterogeneity, while simultaneously establishing the clinical diagnostic applicability of mNGS and, more importantly, the increased utility of dual-triple mNGS analysis tools in robust detection of viral pathogens in SARI.

His hope for the research

Dr Ogunbayo says: “This research generated vast pioneering information and data in Africa that could guide and influence policy in the adoption of clinical metagenomics, especially in cases where conventional methods of diagnosis yielded no results. Hopefully, this could lessen mortality due to respiratory infection in children.

Before studying in the field of medical Microbiology and Virology, he wanted to be a psychiatric nurse, but instead chose his current field of study because of his interest in the microbial world and pathology.

“It’s a feeling one cannot really put into words. A part of me feels like it is a ‘dream come true’ and another part of me feels like ‘this is a milestone achieved, but it’s just a stepping stone to further milestones to be achieved’.

“What is next is for me to dive into the world of policy-influencing research, give back to the academic community through student supervision, and work on my journey to becoming an emerging researcher. This is the reason I have taken a postdoctoral position at the UFS-NGS Unit under the mentorship of Prof Martin Nyaga.”

Prof Nyaga says: “Looking back at Emmanuel’s doctoral journey, it brought out the best in him in every aspect of the study. Longitudinal studies are hectic in the sampling phase, and all the ethical clearances that a study must achieve prior to beginning the sampling and the laboratory work can be very frustrating. Soon after his study was approved, the pandemic lockdown level 5 rules were applied, which meant he had to pause on the study. However, his focus, positive mindset and his ability to work in close consultation with his supervisor enabled him to finish this study in the best way possible. I am very proud of him.”

The launch of a unique conservation project
2011-06-06

 

Our Department of Animal, Wildlife and Grassland Sciences launched a very special pilot project at Woodland Hills Wildlife Estate in Bloemfontein on Friday 03 June 2011, which aims to eventually aid in the conservation and study of one of Africa’s most graceful animals.

The project aims to provide the scientific basis needed for making future decisions in the best interests of the giraffe in the Kgalagadi Transfrontier Park in the Northern Cape and involves collaring and monitoring the behaviour and movement of these animals via GPS.

Based on the public interest in the giraffe and the increased impact of the growing giraffe population on the vegetation in the area, SANParks has been considering the translocation of a number of Kgalagadi giraffe. Due to limited information regarding their adaptation success and potential impact on their new environment, thorough planning and subsequent monitoring of the species is required.

Mr Francois Deacon from our university decided to undertake a PhD study to address the existing challenges. This will be the first study of its kind, undertaken on giraffe.

He says he decided on this project because of his love for animals and conservation. “There are nine sub-species of giraffe and seven of these are already endangered. I want to involve people and make them aware of the plight of the animals and the need for conservation,” he said.

The project kicked off on Friday morning, with a group of students and curious nature-lovers tracking a herd of giraffe at Woodland Hills. The challenge laid in identifying one of the animals which could easily be collared with a GPS device, tranquilising it, and applying the device, without harming the animal.

After a young bull was identified, it was up to Dr Floris Coetzee, a veterinarian, to get close enough to the animal to tranquilise it, and to the group of students to catch it and hold it down. All this was done perfectly and the animal was fitted with its new collars. The collars were designed and made by Mr Martin Haupt, who gained extensive experience in the design of similar collars for other research studies.

Mr Deacon will spend the following two weeks personally monitoring the animal constantly, to ensure that the collars do not cause any discomfort or injury and to determine whether it should be removed or adapted.

It has taken Mr Deacon over a year to plan the collaring process and the associated study. He says the main challenges in the project are financial, since it will cost approximately R500 000 to run over five years.

Thus far he has been supported by Mr Pieter Malan of Woodland Hills, Mr Cas Kempff of Cas Kempff Consulting Engineers and Prof. Frans Swanepoel of the UFS’ Directorate of Research Development, all of whom have been benefactors of the project.
Information gathered from the pilot project will provide the data to assess how to best fit the collar onto the giraffe to ensure that the animal is comfortable and that the collar will last in the wild.  Scientific data will be generated and processed for use by the Woodland Hills Wildlife Estate management.

Should the pilot project be successful, between four and eight giraffe in the Kgalagadi will be tracked using the satellite GPS collars. The GPS collars will enable the constant recording of the location of individual giraffe for up to 2 years. This will allow control and monitoring of the animals in real-time.

The main benefits of the project include, amongst others, improved decision-making, informing tourism development, education and community involvement, improved sustainability and improved cross-border collaboration between South Africa and Botswana.
