In pursuit of efforts to advance research on viruses and disease control, the United States-based Centre for Disease Control and Prevention (CDC) has made a commitment to enhance the University of the Free State (UFS) Next Generation Sequencing (NGS) Unit’s data collection systems and further empower its staff and students.

UFS and US guests explore areas of mutual; cooperation

During a visit to the university in early December last year CDC delegation, Dr Michael Bowen and Dr Mathew Esona, a meeting was held with the lead Researcher at the UFS-NGS Unit, Dr Martin Nyaga; Senior Director of the UFS Directorate Research Development, Dr Glen Tylor; Director of UFS Office for International Affairs, Cornelius Hagenmeier; and Dr Saheed Sabiu Postdoctoral Research Fellow in the Faculty of Natural and Agriculture Sciences. It was in this meeting that areas of mutual collaboration and engagement between the two institutions which include technology transfer, funding and wet and dry laboratory quality control and capacity development were identified.

The UFS-NGS Unit, established in 2016, enjoys longstanding networking and collaborative ventures with renowned researchers in Africa, the USA, and Europe – which in return, have contributed immensely to the research activities of the university as a whole.

Dr Nyaga said in an effort to advance genomics research in the NGS Unit, the visitors have committed themselves to initiate and further enhance capacity development for the unit’s staff and students.

US guests impressed with advanced equipment at UFS

The CDC delegation were intrigued that the UFS also operates a Miseq Illumina platform like the one used at their enteric-viruses laboratory. It could thus be in line to assist in developing exclusive pipelines for the analysis of NGS data generated by the UFS-NGS Unit.

This is a personal sequencing system, which is a powerful state-of-the-art next-generation sequencer. It uses sequencing-by-synthesis technology capable of sequencing up to 15GB of high-quality filtered bases per run, with up to 600 base-pair read lengths. This allows the assembly of small genomes or the detection of target variants with unmatched accuracy, especially within homo-polymer regions.

UFS and CDC engagements still on

Further engagements about the identified areas of collaboration are ongoing between Hagenmeier, Dr Bowen, and Dr Nyaga, who are currently working on appropriate mechanisms to enact the envisaged collaboration between the two institutions.

The NGS Unit received research awards from the World Health Organisation, South African Medical Research Council, Poliomyelitis Research Foundation, and the National Research Foundation for different aspects of genomics research, and more recently from the Bill and Melinda Gates Foundation for the Enteric Viruses Genome Initiative, involving four African countries (South Africa, Ghana, Malawi, and Cameroon).

Prof Tredoux turns theories regarding the formation of metals on its head

The latest research conducted by Prof Marian Tredoux of the Department of Geology, in collaboration with her research assistant Bianca Kennedy and their colleagues in Germany, placed established theories regarding how minerals of the platinum-group of elements are formed, under close scrutiny.

The article on this research of which Prof Tredoux is a co-author – ‘Noble metal nanoclusters and nanoparticles precede mineral formation in magmatic sulphide melts’ – was published in Nature Communications on 6 September 2013. It is an online journal for research of the highest quality in the fields of biological, physical and chemical sciences.

This study found that atoms of platinum and arsenic create nanoclusters, long before the mineral sperrylite can crystallise. Thus, the platinum does not occur as a primary sulphur compound. The research was conducted at the Steinmann Institute of the University of Bonn, Germany, as well as here in Bloemfontein.

Monetary support from Inkaba yeAfrica – a German-South African multidisciplinary and intercultural Earth Science collaborative of the National Research Foundation (NRF) – made this research possible. Studies are now also being conducted on other metals in the precious metal group, specifically palladium, rhodium and ruthenium.

The discovery of the nanoclusters and the combination with arsenic can have far-reaching consequences for the platinum mine industry, if it can be utilised to recover a greater amount of platinum ore and therefore less wastage ending up in mine dumps. This will signify optimal mining of a scarce and valuable metal, one of South Africa’s most important export products.

For Prof Tredoux, the research results also prove thoughts she already had some twenty years ago around the forming of platinum minerals. “Researchers laughed in my face, but the evidence had to wait for the development of technology to prove it.” Young researchers were very excited at recent congresses about the findings, since the new models can bring new insights.

“Chemistry researchers have been talking about platinum element clusters in watery environments for quite a while, but it was thought that these would not appear in magmas (molten rock) due to the high temperatures (>1 000 degrees celsius).”

Prof Tredoux has already delivered lectures at congresses in Scotland, Hungary, Sweden and Italy on this research.
