New research bites back at rodent problem in townships

29 August 2025 | Story Precious Shamase

Pictured are Prof Steven Belmain, Dr Hayley Thompson, and Prof Lourens Swanepoel during their visit to South Africa to kick off a collaborative One Health research project aimed at addressing rodent-related health risks in townships – an initiative that unites local and international experts in the pursuit of safer, community-driven solutions.

A collaborative research project is underway in South African townships to combat the pervasive rodent problem and its impact on human health. Led by Prof Peter Taylor, Professor-in-Residence in the UFS Afromontane Research Unit and affiliated with the UFS Department of Zoology and Entomology, the initiative brings together experts from the UK's Natural Resources Institute (NRI), including Prof Steven Belmain and Dr Hayley Thompson, and South African institutions such as the UFS and the University of Venda.

This 'One Health' approach acknowledges the interconnectedness of human, animal, and environmental well-being. The team visited laboratory facilities at the UFS campuses in Bloemfontein and Qwaqwa, the latter being near Phuthaditjhaba township – a key research site alongside Lwamando in Limpopo.

The multidisciplinary project involves local farmers and university departments, integrating expertise in advanced techniques such as high-performance liquid chromatography (HPLC) and mass spectrometry, molecular virology and microbiology, genome sequencing, and parasitology. Social scientists, such as Dr Shingirayi Chamisa, a lecturer in the UFS Department of Industrial Psychology, are also involved to understand community perceptions and current rodent control methods, including the impact on mental health.

The research will investigate the health risks associated with rodent infestations, including food contamination with poison residues and fungal toxins, and the transmission of disease to humans and livestock through direct contact or parasites. Practical trials will evaluate methods to reduce food contamination.

Significantly, the project will explore novel and humane rodent control strategies, such as contraceptive baits, offering a safer alternative to rodenticides. Recent concerns about rodenticide-related deaths in townships have increased pressure for safer, ecological solutions.

This research holds significant promise for developing sustainable and effective solutions to mitigate the negative impact of rodent pests on the health and livelihoods of township residents. The international and local collaboration, guided by a holistic 'One Health' perspective, marks a crucial step towards addressing this challenging issue. Prof Taylor expressed his appreciation for the enthusiastic engagement of all collaborators, highlighting the potential for a truly transdisciplinary project to find meaningful and ecologically sound solutions to rodent-borne pathogens and food contamination in South African townships.

Care centre goes high-tech to help sexual abuse victims

Rape is one of South Africa’s most pressing social problems. Rape levels in the country are often discussed and reported on, but it does not deter perpetrators from this behaviour. According to Africa Check, of the more than 42 000 rape cases reported in 2015, 15 790 were child rape cases.

In an effort to assist victims of sexual assault and rape, the University of the Free State (UFS) Department of Family Medicine adopted the Tshepong Thuthuzela Care Centre, under the leadership of UFS lecturer Dr Mariaan Kotze.

The Discovery Fund donated a colposcope to Tshepong Thuthuzela Care Centre, an instrument that works with the help of a bright light and which is used to examine victims of abuse. It has also become a standard of good practice in the assessment of child abuse worldwide. According to Dr Kotze, the new instrument will also be used for training health practitioners by rendering clinical forensic services to abuse victims.

Managing complex issues

The care centre works with between 80 and 120 victims of rape each month, a third of whom are children under 14 years of age. According to Dr Kotze, the management of child sexual abuse victims is more complex than with adults; as there is a higher chance of missing or over-diagnosing abnormalities. Also, she says, the examination process is often observed by a group of healthcare practitioners, an experience which is often intrusive and intimidating for the child. With the colposcope, the timeframe of the examination is shortened, and can be captured and viewed in real time, without the victim being present.

Best care for victims

The colposcope is a magnifier and light source used during gynaecological examinations. It is instrumental in providing the best care to victims of sexual abuse, and helps diagnose and assist in the treatment of cases of abuse. Its ability to capture and review images at the time of examination allows for retrospective research, and improves the ability of expert witnesses in court cases.
