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

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.

UFS boasts with most advanced chemical research apparatus in Africa 

The University of the Free State’s (UFS) Department of Chemistry now boasts with some of the most advanced chemical research apparatus in Africa after the latest addition, a nuclear magnetic resonance (NMR) spectrometer, was inaugurated today by the Rector and Vice-Chancellor, Prof Frederick Fourie.  The NMR is used to analyse molecular structures. 

Last month the Department of Chemistry celebrated the installation of the most advanced single crystal X-ray diffractometer in Africa.  The diffractometer provides an indispensable technique to investigate among others the solid state of compounds for medicinal application.

“Three years ago the UFS executive management realised that, if we want to build a university of excellence, we should invest in research.  We started to think strategically about chemistry and decided to bring the apparatus at the Department of Chemistry on a more competitive standard.  Strategic partnerships were therefore secured with companies like Sasol,” said Prof Fourie during the inauguration ceremony.

“The installation of the NMR symbolises the ability of the UFS to turn academic areas around.  I hope that this is the beginning of a decade of excellence for chemistry at the UFS,” said Prof Fourie.

”The catalogue value of the Bruker 600 MHz NMR is approximately R11 million.  With such an advanced apparatus we are now able to train much more post-graduate students,“ said Prof Jannie Swarts, head of the Division Physical Chemistry at the UFS.

”The NMR is the flagship apparatus of the UFS Department of Chemistry that enables chemists to look at compounds more easily at a molecular level.  Research in chemistry is critically dependent on NMR, which is a technique that can determine the composition of reactants and products in complicated chemical reactions, with direct application is most focus areas in chemistry,“ said Prof Swarts.

”Parts of the spectrometer consists of non-commercial items that were specifically designed for the UFS Department of Chemistry to allow the study of unique interactions in e.g. rhodium and platinum compounds,” said Prof Swarts.

According to Prof Swarts the NMR enables chemists to conduct investigations on the following:

To evaluate for example the complex behaviour of DNA in proteins as well as the analysis of illegal drugs sometimes used by athletes. 
It provides an indispensable technique to investigate compounds for medicinal application for example in breast, prostate and related bone cancer identification and therapy, which are currently synthesised in the Department of Chemistry.  
It can also be applied to the area of homogeneous catalysis where new and improved compounds for industrial application are synthesized and characterised, whereby Sasol and even the international petrochemical industry could benefit. This analytical capacity is highly rated, especially in the current climate of increased oil prices.
The NMR can detect and identify small concentrations of impurities in feed streams in the petrochemical industry, e.g. at Sasol and also the international petrochemical industry.  These minute amounts of impurities can result in metal catalyst deactivation or decomposition and can cause million of rands worth in product losses.
It is indispensable for studying the complexity of samples that is non-crystalline. These materials represent the vast majority of chemical compounds such as solvents, gasoline, cooking oil, cleaning agents and colorants as examples. 

According to Prof Swarts the general medical technique of MRI (magnetic resonance imaging) in use at larger hospitals, is based on NMR technology.

”The NMR apparatus enabled the Department of Chemistry to characterise complex molecules that were synthesised for the multi-national company, FARMOFS-PAREXEL, and to negotiate research agreements with overseas universities,” said Prof Swarts.
