AEVGI advances Next-Generation Sequencing in Africa
Prof George Armah, Noguchi Memorial Institute for Medical Research, Ghana; Prof Carl Kirkwood, Bill and Melinda Gates Foundation, USA; Cornelius Hagenmeier, Director: Internationalisation, UFS; Prof Gert van Zyl, Dean: Health Sciences; Dr Martin Nyaga, Senior Lecturer in the NGS Unit; Prof Joyce Tsoka-Gwegweni, Vice-Dean: Health Sciences; Dr Glen Taylor, Senior Director: Research and Development; Prof Jeffrey Mphahlele, Vice-President, South African Medical Research Council.

The inaugural edition of the University of the Free State (UFS) Next-Generation Sequencing (NGS) Data and Bioinformatics Workshop, hosted by the UFS-NGS Unit in the UFS Faculty of Health Sciences, marked a new beginning for the advancement of NGS in Africa under the auspices of the African Enteric Viruses Genome Initiative (AEVGI), which was recently funded by the Bill and Melinda Gates Foundation.

The AEVGI will generate rotavirus genomes at the UFS-NGS Unit to investigate the long-term effects of the introduction of the monovalent RV1 vaccine in three African countries – Ghana, Malawi, and South Africa.

The workshop attracted over 90 participants from 15 national and international institutions, with organisations from seven different countries as well as company representatives attending the event. The workshop kicked off with a courtesy call to the Rector and Vice-Chancellor, Prof Francis Petersen, followed by a stakeholder meeting with the executive management of the UFS.

The funding was secured through an award to the principal investigator, Dr Martin Nyaga, and sub-awards to co-investigators, Dr Khuzwayo Jere, Dr Francis Dennis, and Dr Valentine Ndze. According to attendee evaluations of the workshop, the remarkable performance of the workshop instructors was outstanding. Through practical sessions, participants were equipped with knowledge on how to apply several tools of genetic data analysis, using the rotavirus genome as a model to construct and interpret different genomic datasets.

A total of 65 students attended the hands-on workshop, the majority of which were from South African higher-education institutions. The organisers are grateful to the sponsors, particularly to the Bill and Melinda Gates Foundation and the University of the Free State, for making the workshop a success. Whitehead Scientific and the South African Medical Research Council also played a major role in the success of the workshop. The local organising committee consisted of Dr Martin Nyaga (host, convener and chair), Dr Saheed Sabiu (secretary), and Mr Stephanus Riekert (principal ICT support).

Research on locomotion of giraffes valuable for conservation of this species

Technology was used in filming the giraffes.
According to research, giraffes will slow
down when a drone is positioned
approximately 20 - 30 m away. When the
drone moves closer, they will revert
to galloping.

The meaning of the Arab term Giraffe Camelopardalis is ‘someone who walks fast’. It is precisely this locomotion of their longnecks that encouraged researchers, Dr Francois Deacon and Dr Chris Basu, to study the animals more closely.

Despite the fact that giraffes are such well-known animals, very little research has been done on the manner in which these graceful animals locomote from one place to the next. There are only two known ways of locomotion: the slower lateral walking and the faster galloping. Most animals use these ways of moving forward. It is unknown why giraffes avoid intermediate-speed trotting.

Research of great value to the industry
Research on the manner in which giraffes locomote from one place to the next will assist the industry in understanding aspects such as their anatomy and function, as well as the energy they utilise in locomoting from one place to another. Information on the latter could help researchers understand where giraffes fit into the ecosystem. This data is of great value for large-scale conservation efforts.

Universities working together to collect data
Dr Basu, a veterinarian at the Royal Veterinary College in the UK, has studied the animals at a zoo park in the United Kingdom. He visited the University of the Free State (UFS) in order to expand his fieldwork on the locomotion of giraffes. This study was done in cooperation with Dr Deacon from the Department of Animal, Wildlife, and Grassland Sciences at the UFS. Dr Deacon is a specialist in giraffe habitat-related research in South Africa and other African countries.

The fieldwork for the research, which was done in the Woodland Hills Wildlife Estate and the Willem Pretorius Nature Reserve, preceded research on the movement and the forces involved in the locomotion of giraffes. Due to the confined fenced area in the zoo park, it was practically impossible to study the animals at speed. “The study of actions ‘faster than walking’ is crucial for gathering data on, inter alia, the frequency, length, and time associated with each step.


Technology such as drones offers unique
opportunities to study animals like giraffes.



Technology used to ensure accuracyTechnology such as drones offers unique opportunities to study animals like giraffes. Apart from the fact that it is possible to get high-quality video material of giraffes – moving at speed – it is also a very controlled device that ensures the accuracy of data.

It is the first time ever that a study has been done on the locomotion of giraffes with this level of detail.
Research on the study will be published in the Journal of Experimental Biology.

The project was approved by the UFS ethics committee.
