It was recently discovered that bacteria are capable of growing inside bottles of disinfectants, hand sanitisers and antiseptics. These cleaning products, which are actively used in South African hospitals, are doing more harm than good by contaminating the environment they are designed to clean. Upon testing, some of these contaminated bottles harbouring harmful microorganisms were still actively in use in hospitals and instead of killing microorganisms, the contaminated cleaning solutions were spreading pathogens throughout the hospital with their use. 

This is according to Samantha Mc Carlie from the Department of Microbiology and Biochemistry at the University of the Free State (UFS). She, with her promotor, Prof Robert Bragg, were part of a workshop at the Africa Health Exhibition – the biggest gathering of health care professionals in South Africa and Africa. This was held at Gallagher Estate, Midrand, from 17 to 19 October 2023. 

Increasing mortalities in health-care setting

In a workshop titled: “Developing and sustaining safe health-care environments”, they were part of the main presenting panel, together with Caroline Bilen from the Compass Health Consultancy in Dubai 

Prof Bragg, whose main research is in disease-control, first in the agricultural industry, and now human health, started off the session by highlighting the problems with the increasing mortalities in the health-care setting. He presented data indicating that in the not too distant future, deaths from hospital-acquired infections would be the leading cause of human deaths. “This problem is rapidly growing as most of the pathogens which people contract while in hospital are now resistant to antibiotics, making them very difficult to treat,” he explained.

He used an analogy from San Tzu from the book The Art of War to explain why humankind is losing the war against the microbes. “San Tzu stated that if you know yourself and know your enemy, you will be victorious in every battle. On the other hand, if you do not know yourself or the enemy, you will be defeated in every battle. He pointed out that we do not know the enemy and we do know ourselves (or rather the weapons we have to defeat the enemy) and for this reason we are being defeated,” according to Prof Bragg. 

He continued: “We know the names of the different pathogens causing diseases, but do we really understand them? The answer to that must be ‘no’. A typical example is people are using ethanol-based or chlorine-based products to disinfect and then they wonder why there are increasing problems with Clostridioides difficile infections. If we knew the enemy, we would know that this bacterium producers endospores  and chlorine and ethanol-based disinfectants do not inactivate bacterial endospores, and so will not kill this bacterium,” said Prof Bragg. 

He stated that a major concern for hospitals is that they are currently unaware of whether the disinfectants they are using are effective against the pathogens in their hospital. It is assumed that their cleaning products are working but no testing is being done.

Bacterial resistance to disinfectants

Mc Carlie, in her presentation, highlighted the development of bacterial resistance to disinfectants and why this is important in the health-care setting. She pointed out that the standards for the registration of disinfectant products is based on the use of reference strains of bacteria.

“Bacteria found in hospital environments often exhibit significantly greater resistance to disinfectant compounds compared to the standard strains used for product testing. The presence of these resistant bacteria can result in microbial growth and contamination within containers of disinfectants, hand sanitisers, and antiseptics intended for hospital cleaning purposes. Instead of effectively eliminating microorganisms, these contaminated products inadvertently spread these resilient bacteria throughout the hospital environment, contributing to overall contamination,” said Mc Carlie.

She also discussed the consequences of using incorrectly diluted disinfectant products at concentrations that will not be effective against resilient hospital pathogens. 

Prof Bragg finished the session with a discussion on the solutions to the current problem and highlighted the need for a paradigm shift in medicine. “The current paradigm, since the discovery of antibiotics, has been treatment. As we are entering into a post-antibiotic era, this paradigm of treatment needs to change to one of ‘prevention’. The old saying ‘Prevention is better than cure’ has never been more true.”

He concluded by discussing various options which could be used when focus is placed on biosecurity for the prevention of hospital-acquired infection; including the installation of UV lights, monitoring of the laundry process, correct disinfecting of surfaces, using products with proven efficacy against the pathogens isolated from the different health-care setting and finally, the use of antimicrobial bedside privacy curtains.

The workshop ended with a panel discussion on biosecurity and the efforts needed to reduce the ever-increasing numbers of hospital-acquired infections. It is hoped that the message of this workshop will have a significant impact on the reduction of hospital acquired infections.

“At the UFS, we want to produce graduates for the world, and we need to ensure that we use our knowledge to uplift society”
— Prof Francis Petersen, 14th Vice-Chancellor and Rector of the University of the Free State (UFS)

On Friday 19 May 2017, the University of the Free State (UFS) celebrated the inauguration of its 14th Vice-Chancellor and Rector, Prof Francis Petersen. The formal inauguration was held in the Odeion Theatre on the Bloemfontein Campus. The ceremony was preceded by a week-long welcoming programme on the three UFS campuses.

The guest list included representatives from local and provincial government, vice-chancellors and rectors from across South Africa, and senior members of the university’s executive management.

During the inaugural address, Prof Petersen paid tribute to his predecessors for the role they played in making the university what it is today. This included former rectors and vice-chancellors who attended the ceremony, such as Prof Francois Retief and Prof Frederick Fourie, and Prof Stef Coetzee and Prof Jonathan Jansen who were unable to attend.

Prof Petersen characterised 2015 and 2016 as watershed years for the South African higher-education system. “The Rhodes Must Fall, and subsequent Fees Must Fall student and staff protests challenged us, and re-energised a critical engagement around the purpose of the university in an equal society, both as a site of complicity and as a potential agent for social change,” said Prof Petersen.

He committed himself to developing the UFS into an institution that will have an even greater impact than before.

“This institution I am striving to establish will be one that responds positively to inclusivity, diversity, and transformation, and which can incorporate these values into our curriculum, scholarship, and research in a productive way,” said Prof Petersen.

Prof Petersen emphasised the importance of the three-campus model. “The University of the Free State is ONE university with three campuses: the Bloemfontein Campus, our South Campus, and the Qwaqwa Campus. I am committed to align the activities of the three campuses, and to integrate our activities to a greater extent.

“We must work together to infuse each campus with the values we have identified as essential if we are to make our mark as a united University of the Free State: academic excellence, diversity and inclusivity, and innovation.”

The Chancellor, Dr Khotso Mokhele, had the honour of handing over the gown to Prof Petersen. Prof Lis Lange, Vice-Rector: Academic, explained the relationship between the university and the Basotho people, and how this relationship is honoured through the official procession gowns of the UFS. The Basotho blanket is worn by kings, and the university therefore hopes that the symbolism of the gown would be a source of inspiration to Prof Petersen.

The event was concluded by congratulatory messages from former colleagues and the President of the Student Representative Council on the Bloemfontein Campus, SK Luwaca. The event was elegant and graceful – the inaugural address was thought-provoking and inspiring.

Welcoming Ceremonies:

The week of 11-19 May 2017 was one of the highlights in this year’s calendar for staff and students of the University of the Free State (UFS), with various ceremonies taking place to welcome Prof Francis Petersen – who assumed his duties on 1 April 2017 – as the 14th Vice-Chancellor and Rector. The festivities culminated in the official inauguration ceremony at the Bloemfontein Campus on 19 May 2017.
 
The Qwaqwa Campus welcoming ceremony took place on Thursday 11 May 2017, attracting a wide spectrum of community leaders from the area. Prof Petersen was welcomed by representatives from the two trade unions, National Education Health and Allied Workers Union (Nehawu) and UVPERSU, as well as representatives from the Student Representative Council (SRC), the Thabo Mofutsanyana Education District, and the House of Traditional Leaders. Paramount Queen Mopeli of the Bakoena Royal House bestowed a special honour upon Prof Petersen by clothing him in a traditional Basotho blanket and hat. She said, "From our heart of hearts, welcome, Prof Francis ..., and all Godspeed during your tenure."
 
The South Campus in Bloemfontein hosted a welcoming ceremony for the new Vice-Chancellor and Rector on 18 May 2017. The ceremony included a number of vocal performances and messages from various stakeholder groups. The same afternoon, the Institute for Reconciliation and Social Justice (IRSJ) also facilitated a panel discussion, titled Diversity, inclusivity, and social justice and the renewed call for decolonisation, in the Albert Wessels Auditorium (AWO) on the Bloemfontein Campus.

The welcoming ceremonies culminated in an event in the Callie Human Centre on Friday 19 May 2017 at the Bloemfontein Campus, with a number of performances by musicians associated with the UFS, marimbas, drum majorettes from Jim Fouche Secondary School, the Grey College Gumboots, and school choirs from Eunice Secondary School, Brebner Primary School, and Willem Postma Primary School. Representatives from key stakeholders such as Nehawu, UVPERSU, the Campus Ministries Forum, SRC, Alumni, Convocation, and the UFS Council had the opportunity to convey their messages of welcome to Prof Petersen.
 
The formal inauguration ceremony took place in the Odeion Theatre on the Bloemfontein Campus the same day.
