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 SciencesFaculty 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.

Stem cell research and human cloning: legal and ethical focal points
2004-07-29

   

(Summary of the inaugural lecture of Prof Hennie Oosthuizen, from the Department of Criminal and Medical Law at the Faculty of Law of the University of the Free State.)

 

In the light of stem cell research, research on embryo’s and human cloning it will be fatal for legal advisors and researchers in South Africa to ignore the benefits that new bio-medical development, through research, contain for this country.

Legal advisors across the world have various views on stem cell research and human cloning. In the USA there is no legislation that regulates stem cell research but a number of States adopted legislation that approves stem cell research. The British Parlement gave permission for research on embryonic stem cells, but determined that it must be monitored closely and the European Union is of the opinion that it will open a door for race purification and commercial exploitation of human beings.

In South Africa the Bill on National Health makes provision for therapeutical and non therapeutical research. It also makes provision for therapeutical embryonical stem cell research on fetuses, which is not older than 14 days, as well as for therapeutical cloning under certain circumstances subject to the approval of the Minister. The Bill prohibits reproductive cloning.

Research on human embrio’s is a very controversial issue, here and in the rest of the world.

Researchers believe that the use of stem cell therapy could help to side-step the rejection of newly transplanted organs and tissue and if a bank for stem cell could be built, the shortage of organs for transplants would become something of the past. Stem cells could also be used for healing of Alzheimer’s, Parkinson’s and spinal injuries.

Sources from which stem cells are obtained could also lead to further ethical issues. Stem cells are harvested from mature human cells and embryonic stem cells. Another source to be utilised is to take egg cells from the ovaries of aborted fetuses. This will be morally unacceptable for those against abortions. Linking a financial incentive to that could become more of a controversial issue because the woman’s decision to abort could be influenced. The ideal would be to rather use human fetus tissue from spontaneous abortions or extra-uterine pregnancies than induced abortions.

The potential to obtain stem cells from the blood of the umbilical cord, bone-marrow and fetus tissue and for these cells to arrange themselves is known for quite some time. Blood from the umbilical cord contains many stem cells, which is the origin of the body’s immune and blood system. It is beneficial to bank the blood of a newborn baby’s umbilical cord. Through stem cell transplants the baby or another family member’s life could be saved from future illnesses such as anemia, leukemia and metabolic storing disabilities as well as certain generic immuno disabilities.

The possibility to withdraw stem cells from human embrio’s and to grow them is more useable because it has more treatment possibilities.

With the birth of Dolly the sheep, communities strongly expressed their concern about the possibility that a new cloning technique such as the replacement of the core of a cell will be used in human reproduction. Embryonic splitting and core replacement are two well known techniques that are associated with the cloning process.

I differentiate between reproductive cloning – to create a cloned human embryo with the aim to bring about a pregnancy of a child that is identical to another individual – and therapeutically cloning – to create a cloned human embryo for research purposes and for healing human illnesses.

Worldwide people are debating whether to proceed with therapeutical cloning. There are people for and against it. The biggest ethical objection against therapeutical cloning is the termination of the development of a potential human being.

Children born from cloning will differ from each other. Factors such as the uterus environment and the environment in which the child is growing up will play a role. Cloning create unique children that will grow up to be unique individuals, just like me and you that will develop into a person, just like you and me. If we understand this scientific fact, most arguments against human cloning will disappear.

Infertility can be treated through in vitro conception. This process does not work for everyone. For some cloning is a revolutionary treatment method because it is the only method that does not require patients to produce sperm and egg cells. The same arguments that were used against in vitro conception in the past are now being used against cloning. It is years later and in vitro cloning is generally applied and accepted by society. I am of the opinion that the same will happen with regard to human cloning.

There is an argument that cloning must be prohibited because it is unsafe. Distorted ideas in this regard were proven wrong. Are these distorted ideas justified to question the safety of cloning and the cloning process you may ask. The answer, according to me, is a definite no. Human cloning does have many advantages. That includes assistance with infertility, prevention of Down Syndrome and recovery from leukemia.
