Dr Nyaga_read more — Dr Martin Nyaga, Senior Lecturer and Researcher: NGS, will be heading the World Health Organisation Collaborating Centre (WHO CC).

The University of the Free State (UFS) has been designated a World Health Organisation Collaborating Centre (WHO CC), and the university’s Next Generation Sequencing (NGS) Unit, in partnership with the World Health Organisation (WHO), will for the next four years be conducting genome sequencing of pathogenic organisms, including rotavirus strains from the African continent.

This centre will be part of the Vaccine Preventable Diseases (VPD) Pathogens Genomics Cluster and will run from September 2020 to September 2024.

Dr Martin Nyaga, Senior Lecturer and Researcher: NGS/Virology, who will be heading the WHO CC, says an institution is designated as a WHO CC by the WHO Director-General and endorsed by the host country’s minister of health to form part of an international collaborative network, carrying out activities in support of the WHO programmess at all levels. A designation as a WHO CC is a time-limited agreement of collaboration between WHO and the designated institution, through which the latter agrees to implement a series of concrete activities, specifically designed for WHO.

A supreme achievement

Says Dr Nyaga: “In my opinion, a WHO CC designation is one of the supreme achievements an institution can be conferred as a recognition for foregoing exceptional collaborative venture with the WHO and showing future potential to assist the WHO with its global programmes and in our case, the WHO Regional Office for Africa region to offer solutions to the WHO VPD Surveillance and pathogens genomics cluster.”

According to Dr Nyaga this designation was awarded to the UFS after the WHO was content with the outcome of a service contract whereby the UFS-NGS unit undertook a pilot rotavirus surveillance project at whole genome level, using two African countries for the pilot, Rwanda and Zambia.

“From the outcomes of the pilot surveillance project between 2017 and 2019, the WHO/AFRO was satisfied with the genomic data that was generated and partially disseminated in scientific databases and journals as a collaborative venture.

“It was thus proposed to strengthen its existing collaboration with the UFS-NGS Unit, which initiated the application process to designate the UFS-NGS unit as a WHO CC, an initiative that has taken approximately 20 months to finalise through the different phases of the application and approvals for the designation,” explains Dr Nyaga.

The purpose of the WHO CC

The new WHO CC will upon request by the WHO, implement agreed work plans in a timely manner and to the highest possible standards of quality and must comply with the referred terms of reference and conditions. These include:

• Conducting genome sequencing of pathogenic organisms causing VPD, including rotavirus strains collected as part of the routine VPD surveillance using NGS technology and analysis of the generated datasets using bioinformatics tools.

• Conducting molecular characterisation of specimens collected during outbreaks and public health emergencies as part of the support for monitoring, preparedness and response to VPD disease outbreaks in Africa.

• Provide technical guidance to WHO on strategies to improve laboratory molecular diagnostics, molecular typing and NGS of rotavirus diarrheal strains and other enteropathogens to detect novel and re-emerging strains.

• Conduct validation of tools and new molecular diagnostics for detection and characterisation of unusual or rare VPD strains to guide studies and development of new vaccines for VPD.

• Organise capacity-building and training workshops on whole genome sequencing of priority VPD pathogenic organisms.

The impact of the WHO CC on the work of the UFS-NGS

According to Dr Nyaga, the designation brings extra responsibilities to his work and to the activities of the UFS-NGS unit. “Such initiatives are very welcome to enhance the business aspects, research and academic activities of the UFS-NGS unit, as the benefits are quite holistic since the collaboration enhances co-ownership of data and offers opportunities to train postgraduate students and other scientists.

“It also expands the research infrastructure and most importantly contributes to policy for numerous African governments in important decisions such as vaccine implementation activities, from an informed point of view and managing public health needs that require rapid response like outbreaks that may lead to pandemics.”

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.
