Growing up, many of us were raised in Christian homes practising specific morals and values, and anything outside of that was considered immoral or even ‘demonic’. However, what happens when you have a dual identity, and you embrace a bit of both?

On 29 June 2022, the University of the Free State Faculty of Theology presented a Table Talk Webinar with Dr Nomfundo Mlisa, titled ‘African Christianity: interconnections between religion, culture, and identity’. These webinars cover a variety of burning topics that deal with contentious issues across the country. Attendees emerged from various parts of the world, including Nigeria and Germany.

Dr Mlisa is a published author, qualified nurse, traditional healer, as well as preacher of the Word. Her talk was based on personal experiences of being Xhosa and being brought up as a member of the Methodist Church of Southern Africa in a strict Christian environment. She was on her journey to becoming a preacher when she realised that she needed to undergo the spiritual healing training (ukhuthwasa) and was faced with resistance from the church minister/s, forcing her to leave church because ukuthwasa was against the church policies.

Her journey has been challenging, because she only acknowledged her ancestral calling at the age of 42, following a series of occurrences that nearly cost her her children. Dr Mlisa hinted that, besides being against church policy, one of the reasons was that the Xhosa nation considered ukhuthwasa to be witchcraft due to the similarity in the pronunciation of words: ukhuthwasa, meaning undergoing spiritual training; ukuthwala, which is an ancient activity of gaining powers for wealth; and ukhuthakatha, meaning witchcraft.

“Rev Mabusela of the Methodist Church invited me back to the church and I was ordained as a reverend. However, my ordination was held at the East London Correctional Services, and it was then that I realised I was a prisoner of faith and tradition,” she said.

Is there a link between ukuthwasa and Christianity?

Besides the fact that philosophy could not prove the linkage, Dr Mlisa said that the link exists, but Christianity has strongly influenced Africans to integrate Christian values into their cultural value systems, as evidenced by various authors. This led to various people with spiritual calling disowning their cultural identities as well as their being.

“In Christianity, there are faith healers and prophets, whereas culturally, we have traditional healers; however, they have one objective, which is to heal the people. But because people wanted to accommodate their gifts in Christianity, such names were given. Furthermore, Christians recognise angels, while traditionally, ancestors are recognised,” she explained.

Looking into different practices in both the Traditional and Christian religions, they both have elements of training, ‘ukhuthwasa’. This is mainly because they all undergo different types of training under a senior person. A senior faith healer trains a junior, whereas a ‘gobela’ trains a traditional healer.

The society is also coming to accept all religions, with most people now wearing traditional healer beads everywhere, including work. There are also traditional healers who are modern doctors, demonstrating that these innate or hereditary abilities are a common language.

Research eradicates bacteria from avocado facility

“The aim of my project was to identify and characterise the contamination problem in an avocado-processing facility and then to find a solution,” said Dr Amy Strydom, postdoctoral fellow in the Department of Microbial Biochemical and Food Biotechnology at the University of the Free State (UFS).

Her PhD, “Control of Listeria monocytogenes in an Avocado-processing Facility”, aimed to identify and characterise the contamination problem in a facility where avocados were processed into guacamole. Dr Strydom completed her MSc in food science in 2009 at Stellenbosch University and this was the catalyst for her starting her PhD in microbiology in 2012 at the UFS. The research was conducted over a period of four years and she graduated in 2016. The research project was funded by the National Research Foundation.

The opportunity to work closely with the food industry further motivated Dr Strydom to conduct her research. The research has made a significant contribution to a food producer (avocado facility) that will sell products that are not contaminated with any pathogens. The public will then buy food that is safe for human consumption.


What is Listeria monocytogenes?

Listeria monocytogenes is a food-borne pathogenic bacterium. When a food product is contaminated with L. monocytogenes, it will not be altered in ways that are obvious to the consumer, such as taste and smell. When ingested, however, it can cause a wide range of illnesses in people with impaired immune systems. “Risk groups include newborn babies, the elderly, and people suffering from diseases that weaken their immune systems,” Dr Strydom said. The processing adjustments based on her findings resulted in decreased numbers of Listeria in the facility.

The bacteria can also survive and grow at refrigeration temperatures, making them dangerous food pathogens, organisms which can cause illnesses [in humans]. Dr Strydom worked closely with the facility and developed an in-house monitoring system by means of which the facility could test their products and the processing environment. She also evaluated bacteriophages as a biological control agent in the processing facility. Bacteriophages are viruses that can only infect specific strains of bacteria. Despite bacteriophage products specifically intended for the use of controlling L. monocytogenes being commercially available in the food industry, Dr Strydom found that only 26% of the L. monocytogenes population in the facility was destroyed by the ListexP100TM product. “I concluded that the genetic diversity of the bacteria in the facility was too high and that the bacteriophages could not be used as a control measure. However, there is much we do not understand about bacteriophages, and with a few adjustments, we might be able to use them in the food industry.”

Microbiological and molecular characterisation of L. monocytogenes

The bacteria were isolated and purified using basic microbiological culturing. Characterisation was done based on specific genes present in the bacterial genome. “I amplified these genes with polymerase chain reaction (PCR), using various primers targeting these specific genes,” Dr Strydom said. Some amplification results were analysed with a subsequent restriction digestion where the genes were cut in specific areas with enzymes to create fragments. The lengths of these fragments can be used to differentiate between strains. “I also compared the whole genomes of some of the bacterial strains.” The bacteriophages were then isolated from waste water samples at the facility using the isolated bacterial strains. “However, I was not able to isolate a bacteriophage that could infect the bacteria in the facility.
