The composition of the UFS Council is stipulated in the UFS Statute, which was published in the Government Gazette on 10 March 2023. The Convocation has to elect two (2) external Convocation members (who are neither employees nor students of the UFS) to the Council, as required by the Statute of the UFS. The elected members will serve on the Council for a period of four years.

The Convocation comprises all persons who obtained a formal qualification from the UFS, as well as all permanent and retired academic staff members.

Members of the Convocation are invited to submit written nominations by using the Nomination Form attached hereto.

Every nomination form must be signed by 2 (two) members of the Convocation and must contain the written acceptance of the nomination by the nominee under his/her signature, as well as an abridged CV and a motivation of ± 200 words.

All nominations must reach the office of the Registrar no later than 4 October  2024.

If more than two persons are nominated, an election will be held as stipulated in the Interim Institutional Rules. More information regarding this process will follow at that stage. 

Nominations are to be submitted to:
     e-mail: registrar@ufs.ac.za

or hand-delivered to:
     Mr NN Ntsababa
     Room 51 
     1st Floor
     Main Building
     UFS Bloemfontein Campus

For any enquiries, please contact Mr NN Ntsababa at registrar@ufs.ac.za or +27 51 401 3796.

Kindly take note that late or incomplete nominations will not be accepted or considered.

Each nomination must be submitted separately.

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.
