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.”

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.
