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.

Cohesions and Disruptions Forum
2014-07-15

 
The Institute for Reconciliation and Social Justice at the UFS and the Johannes Stegmann Art Gallery, in partnership with the Vryfees, co-presented an artist and academic forum on 18 July 2014.

The forum, ‘Cohesions and Disruptions: Art as a Key to Transformation’, was aptly timed to coincide with Mandela Day. This event formed part of the transformation strategy of the Vryfees arts festival, aiming to support more diversity and cross-cultural, contemporary art programmes.

“Cohesions and Disruptions is part of the new Program for Innovation in Artform Development (PIKO/PIAD),” said Adri Herbert, Director of the Vryfees. “This includes both the cross-cultural OPENLab 2014, a new Australian/South African laboratory for early and mid-career South African artists, and a partnership with the Australian based SituateArt in Festivals initiative, managed by Salamanca Arts Centre in Hobart, Tasmania.”

The forum’s keynote speaker was Lee-Ann Tjunypa Buckskin. She is a Narungga, Wirangu, Wotjobaluk woman from South Australia and Victoria respectively. She is well known throughout the Aboriginal and Torres Strait Islands and broader arts communities. Buckskin’s presentation was titled ‘Building Young Indigenous People’s Lives through Art and Culture in Remote Central Australia.’

Buckskin spoke broadly about her involvement with youngsters – often poverty stricken and sniffing petrol – in remote areas of Australia. She explained how the arts have given the youth a chance at rehabilitation and hope for the future.

After her presentation, she was joined by Dr Willy Nel, lecturer at the UFS School of Education Studies. Dr Nel completed his PhD among the Khomani San in the Kalahari. 

Other forum speakers who presented their work included:
Dr Mari Velonaki, Director of the Centre for Social Robotics at the National Institute for Experimental Art at the University of New South Wales, Sydney;
Dr Nigel Helyer of Sonic Objects; Sonic Architecture, Sydney;
Bec Dean, Curator at Performance Space, Sydney;
Jesse Olivieri, co-founder of Parachutes for Ladies in Sydney; and
Cigdem Aydemir, Vryfees visual artist for 2014.

“Given the histories and present experiences of human rights violations and racial discrimination that indigenous people in Australia and South Africa are subjected to, we are particularly honoured to have Lee-Ann (Buckskin) as a guest speaker,” said Prof Andre Keet, Director of the UFS Institute for Reconciliation and Social Justice.
