Marcele Vermeulen, a graduate from the Department of Plant Sciences, explores possible threats to crop production; contributing to food security in South Africa.
Global food security is currently threatened both by climate change and the low diversity of crops relied on by humankind to feed a growing world population. Marcele Vermeulen, a graduate in the Department of Plant Sciences who will receive her PhD at the December graduation ceremonies at the University of the Free State (UFS), is part of a team that is working hard to add to the diversity of staple foods in South Africa.

In the drive to focus on alternative crops, Marcele is researching the crop, Amaranthus cruentus, (grain amaranth). It is more tolerant to environmental stress for large-scale production, thereby also diversifying staple crops.

Relatively new development

“Amaranthus cruentus is an excellent candidate due to its high nutritional value and tolerance to drought and high temperatures. It can be mixed with conventional maize meal, to increase the protein intake of its consumers,” said Marcele.

The production of A. cruentus as a grain crop in South Africa is a relatively new development.

In her research, exploring the possible threats to crop production and paying particular attention to dominant plant pathogens in the Amaranthus cruentus, Marcele found a correlation between fungal pathogens and insect pests. 

Insect pests can influence plant diseases

Although reports on fungal pathogens and pests specific to A. cruentus are limited to and information for South Africa is limited to this study, there is a possibility that by controlling insect pests such as weevils, one might also be able to control fungal pathogens of Amaranthus cruentus.

Marcele believes that control of weevil pests should thus be the focus of future pest and pathogen management strategies and breeding programmes in A. cruentus.  

“Knowledge gained in my thesis will hopefully aid in the development of future cultivation practices, integrated pest/pathogen management programmes, as well as for the registration of crop protection products for A. cruentus,” Marcele added.

New Division of Virology to deliver crucial services for HIV diagnosis and resistance testing
2015-12-14

The establishment of a Division of Virology within the Department of Medical Microbiology, under the joint auspices of the UFS and the National Health Laboratory Service (NHLS), reflects the continued growth within Virology.  Dr Dominique Goedhals, Head of the Division, says the division will also provide training of undergraduate medical students, medical technologists and technicians, and registrars.

The newly established Division of Virology at the University of the Free State will be one of only five laboratories in the country to be involved in crucial diagnostic and testing services for HIV viral load monitoring, early infant diagnosis, and HIV resistance testing.

The Virology Diagnostic Laboratory serves as the reference laboratory for all HIV National Priority Programme samples for the Free State and Northern Cape provinces.

Medical staff at the laboratory will provide a 24-hour consultative service, as well as outreach programmes to district laboratories in the Free State and Northern Cape where pathologists are not available. 

Dr Dominique Goedhals, Head of the Division of Virology, says this division, under the joint auspices of the UFS and the National Health Laboratory Service (NHLS), reflects the continued growth within Virology.

The division will not only deliver this critical diagnostic service, but will also focus on training and teaching, as well as research.

Teaching and training activities include teaching of undergraduate medical students, medical technologists and technicians, and registrars.  The postgraduate science programme has a high output of honours, master’s and doctoral students in Virology.  The intern medical scientist programme is also active, with five interns having successfully submitted their portfolios since the programme was implemented in 2010.

Research activities under the Head of Research, Prof Felicity Burt, have also expanded and continue to show increases in publication output and acquisition of grant funding.  Established research groups within the Division of Virology focus on vector-borne and zoonotic viruses, human papilloma viruses (HPV), and human immunodeficiency virus (HIV), as well as work with a number of international collaborators.
