UFS debate
Join the UFS, University of Pretoria (UP) and the Motsepe Foundation in the upcoming Universities in Dialogue (UiD) conversation taking place on 20 August 2019.

Universities in Dialogue (UID) is an initiative driven by the Motsepe Foundation, which is aimed at promoting intergenerational, mixed-gender, and race conversations about socio-economic issues affecting South Africa. 

The purpose of the debate is to discuss alternative measures to advance gender equality and likeness across society, provide a platform for the youth to voice their concerns and deliberate in solution-driven conversation with renowned professors, and to create a space for students to collaborate among one another in order to solicit, drive, and fast-track transformation and nation-building in our country. 

According to research conducted by the Motsepe Foundation, the average age of the South African population is 26 years, which is why the initiative aims to generate debate among the youth on the most pressing concerns facing South Africa today. 

The foundation invited Kovsies to join the 2019 UiD dialogue, together with students and professors from the University of Pretoria (UP), the University of Cape Town (UCT), and Wits University. 

The dialogue/series is interlinked to the Motsepe Foundation Women’s Unit mandate, which aims to initiate interventions that will bring social, economic, and political empowerment to women and girls. The first debate, in partnership with the University of Pretoria, is scheduled for Women’s Month and will focus on the equal rights and participation of women.

The debate motion states: South Africa requires a feminist government to advance gender equity and equality across all sectors of society.

Event details are as follows:

Date: Tuesday, 20 August 2019
Time: 16:00–19:00

Venue: Access the dialogue live on 20 August 2019 here

Dr Charlotte Boucher and Lindi Heyns examine possible anti-microbial activity in the skin of Western olive toad species
2014-12-22

 

Researchers Lindi Heyns and Dr Charlotte Boucher are working together on an interdisciplinary project between the Departments of Zoology and Entomology and Veterinary Biotechnology at the University of the Free State (UFS). The focus of their research is on the preliminary biochemical description of skin secretions in some South African toads.

The project forms part of an Honours study executed by Dwayne Pike under Heyns’ supervision. He is co-supervised by Dr Boucher who is assisting with the biochemical and microbiological assays.

Dr Boucher said, “Amphibians are characterised by the presence of cutaneous glands spread over the skin. There are two types of glands, namely mucous and granular (poison), located on the inner surface of the epidermis. Mucous glands are widely dispersed over the skin, while granular glands can be grouped and enlarged in specific regions. Mucous glands are generally associated with maintenance of humidity and cutaneous respiration, whereas granular glands function in chemical defence against predators and/or microbial infection. Studies indicate that the compounds produced by the granular glands belong to numerous chemical classes with diverse pharmacological activities.”

The products secreted by granular glands are rich in low molecular weight constituents of varied molecular types, including proteins, peptides and toxins. These secretions make the toad foul-tasting to predators and even toxic to other frog species. In addition, amphibians offer an attractive source of novel antimicrobials. Studies indicate that as a response to inhabiting microorganism-rich environments they synthesise and secrete a diverse array of antimicrobial peptides (AMPs) as an innate form of defence. Extensive research by various other research groups has been carried out on antimicrobial peptides of the genus Rana; however, hardly any studies have investigated the antimicrobial activity of African frog species.

The focus of this preliminary project is to determine the protein composition of the glandular secretions of the Western olive toad (Amietophrynus poweri), using biochemical tests, such as SDS-PAGE also known as protein gel electrophoresis combined with mass-spectrometry used to identify unknown peptides and proteins. This will give us an overview of the composition of the glandular secretions. Furthermore, we are also looking at microbiological tests, which include assays that test for possible anti-microbial activity against various bacterial and fungal species.
