Milton Mogotsi, a PhD student in Medical Virology, was awarded the Dr Lehlohonolo Mathengtheng Trophy at the recently held Faculty of Health Sciences’ Faculty Research Forum.

Mogotsi was the recipient of the trophy for best presentation by a PhD student in the laboratory category. He is supervised by Prof Martin Nyaga, Associate Professor in the Division of Virology and Head of UFS-NGS Unit, and co-supervised by Prof Trudi O’Neill, Professor in the Department of Microbiology and Biochemistry.

The Research Forum offers staff members and postgraduate students an opportunity to present the results of their research. The Faculty Research Forum aims to provide a platform to disseminate outputs and findings of all the research conducted in the faculty, and to also provide junior researchers/postgraduate students exposure.

Results of his study

Mogotsi presented the results of his PhD study titled “Longitudinal gut virome analysis provides insights into early gut colonisation and temporal dynamics in paediatric subjects from the Free State Province, South Africa”. His research sought to understand the longitudinal evolution of viruses colonising the gastrointestinal tract of infants during their first year of life. In this study, metagenomic next generation sequencing was performed on faecal specimens collected longitudinally from a cohort of 17 infants during their first six months. These infants were recruited from three public hospitals around Bloemfontein after consent was attained from the mothers.

The results of this study revealed that the guts of infants are highly colonised by diverse and dynamic viral communities, formed by a richness of different viruses infecting humans, predominantly those that are associated with gastroenteritis in children. These pathogenic agents were detected as early as one day old and increasing in abundance and diversity over time, even in the absence of clinical manifestations.

The detection of such pathogenic viruses highlights the importance of screening for intestinal pathogens at an early age to close existing gaps and enhance the effectiveness of current treatment. In addition, the detection of viruses of unknown origin in faeces of infants underscores the need to extend sampling to mothers to better understand transmission patterns of such pathogens. Importantly, interventions to improve water quality, sanitation, and hygiene at the household level would be very impactful in minimising viral transmissions to infants and reducing the high childhood morbidities and mortalities in Africa.

A great honour

“As an emerging research virologist, presenting at such forums provides me with a platform to introduce my research, but also presents the opportunity to initiate discussions with other researchers, and exchange ideas that can help improve my future scientific approaches,” says Mogotsi.

“Being awarded the Dr Lehlohonolo Mathengtheng Trophy is such a great honour, and it came at the right time when I’m near completion of my PhD. It has really motivated me to work even harder and make sure I obtain this qualification. However, this would not have been possible without the guidance and support from my supervisor, Prof Nyaga. I want to thank him for giving me the opportunity to conduct this research project under his supervision. The continued support and encouragement from my colleagues in the UFS-Next Generation Sequencing Unit is also highly appreciated,” he concludes.

Mogotsi is finalising the write-up of his PhD thesis which he will be submitting in November 2023 for examination and is also preparing manuscripts for submission in high-impact internationally recognised peer-review journals.

Researchers international leaders in satellite tracking in the wildlife environment

2015-05-29

Ground-breaking research has attracted international media attention to Francois Deacon, lecturer and researcher in the Department Animal, Wildlife and Grassland Sciences at the UFS, and Prof Nico Smit, from the same department. They are the first researchers in the world to equip giraffes with GPS collars, and to conduct research on this initiative. Recently, they have been joined by Hennie Butler from the Department of Zoology as well as Free State Nature Conservation to further this research.

“Satellite tracking is proving to be extremely valuable in the wildlife environment. The unit is based on a mobile global two-way communication platform, utilising two-way data satellite communication, complete with GPS systems.

“It allows us to track animals day and night, while we monitor their movements remotely from the computer. These systems make possible the efficient control and monitoring of wildlife in all weather conditions and in near-to-real time. We can even communicate with the animals, calling up their positions or changing the tracking schedules.

“The satellite collar allows us to use the extremely accurate data to conduct research with the best technology available. The volume of data received allows us to publish the data in scientific journals and research-related articles.

“Scientific institutions and the public sector have both shown great interest in satellite tracking, which opens up new ground for scientific research for this university. Data management can be done, using Africa Wildlife Tracking (AWT) equipment where we can access our data personally, store it, and make visual presentations. The AWT system and software architecture provide the researcher with asset tracking, GPS location reports, geo-fencing, highly-detailed custom mapping, history reports and playback, polling on demand, history plotting on maps, and a range of reporting types and functions,” Francois said.

Data can be analysed to determine home range, dispersal, or habitat preference for any specific species.

Francois has been involved in multiple research projects over the last 12 years on wildlife species and domesticated animals, including the collaring of species such as Black-backed Jackal, Caracal, African Wild Dog, Hyena, Lion, Cheetah, Cattle, Kudu, Giraffe, and Black Rhino: “Giraffe definitely being the most challenging of all,” he said.

In 2010, he started working on his PhD, entitled The spatial ecology, habitat preferences and diet selection of giraffe (Giraffa camelopardalis giraffa) in the Kalahari region of South Africa.

Since then, his work has resulted not only in more research work (supervising four Masters students) but also in a number of national and international projects. These include work in the:

Kalahari region (e.g. Khamab Nature Reserve and Kgalagadi Transfrontier Park)
Kuruman region (Collared 18 cattle to identify spatial patterns in relation to the qualities of vegetation and soil-types available. This project took place in collaboration with Born University in Germany)
Woodland Hills Wildlife Estate and Kolomella Iron Ore – ecological monitoring
A number of Free State nature reserves (e.g. Distribution of herbivores (kudu and giraffe) and predators (camera traps)

Francois is also involved with species breeding programmes and management (giraffe, buffalo, sable, roan, and rhino) in Korrannaberg, Rustenburg, Hertzogville, Douglas, and Bethlehem as well as animal and ecological monitoring in Kolomella and Beesthoek iron ore.

Besides the collaring of giraffes, Francois and his colleagues are involved in national projects, where they collect milk from lactating giraffes and DNA material, blood samples, and ecto/endo parasites from giraffes in Southern Africa.

With international projects, Francois is working to collect DNA material for the classification of the nine sub-species of giraffe in Africa. He is also involved in projects focusing on the spatial ecology and adaptation of giraffe in Uganda (Murchison Falls), and to save the last 30 giraffe in the DRC- Garamba National Park.

This project has attracted a good deal of international interest. In June 2014, a US film crew (freelancing for Discovery Channel) filmed a documentary on Francois’ research (trailer of documentary). Early in 2015, a second crew, filming for National Geographic, also visited Francois to document his work.

More information about Francois’ work is available at the GCF website.
