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.

DF Malherbe Memorial Lecture

DF Malherbe Memorial Lecture: Language and language activism in a time of transformation (summary)
Proff Hennie van Coller and Jaap Steyn

Language activism necessary for multilingualism
The awareness is growing that language activism will be needed to bring about a truly democratic multi-lingual society. What is quite clear is that a firm resolve must continuously resist the concentrated pressure on Afrikaans-medium schools (and universities) to allow themselves to be anglicised through becoming first parallel medium, then dual medium, and finally English medium institutions.

Proff Hennie van Coller and Jaap Steyn said this last night (Wednesday night) in the 24th DF Malherbe Memorial Lecture at the University of the Free State. Prof van Coller is head of the Department Afrikaans, Dutch, German and French at the UFS. Both are widely honoured for their contributions to Afrikaans and the promotion of Afrikaans.

They discussed three periods of transformation since 1902, and said about the current phase, which started in 1994:  “Besides all institutions and councils having to be representative of South Africa’s racial composition, places of education were required to open their doors. Quite rapidly this policy has had the result that schools and universities may be solely English medium, but not solely Afrikaans medium. Afrikaans medium institutions — if they claim the right to remain Afrikaans — are quickly branded racist, even though their student body may include all races.

“Education departments are presently exerting great pressure on Afrikaans medium schools to become double or parallel medium schools.  Parallel medium education is an equitable solution provided it can be sustained. Established parallel medium schools, such as Grey College in Bloemfontein, have catered even-handedly for English and Afrikaans speakers for decades. But the situation is different in the parallel medium (and still worse in the double medium) schools that spring up usually at the behest of a department of education.

“Afrikaans schools are converted almost over-night into parallel or dual medium schools without any additional personnel being provided. Depending on the social environment, a parallel medium school becomes reconstituted as a dual medium school on average in five to eight years, and dual medium school becomes an English-only school in two to three years. Some Afrikaans medium schools have become English medium in just three years.

“Though the Constitution recognises mono-lingual schools, officials in the provinces insist that Afrikaans schools become dual or parallel medium; English medium schools are left undisturbed. One must conclude that the tacit aim of the state is English as the sole official language, despite the lip-service paid to multi-lingualism, and the optimistic references to post-apartheid South Africa as a ‘rainbow’ nation.”

They said a recent study has shown that the 1 396 Afrikaans schools in the six provinces in 1993 have dwindled to 844. The fall off in the Free State is from 153 to 97; in the Western Cape from 759 to 564; in Gauteng from 274 to 155; in Mapumalanga from 90 to 3; in the North West from 82 to 13; and in Limpopo Province from 38 to 12.

They said the changes at universities, too, have been severe, as university staffs well know. Ten years ago there were five Afrikaans universities. Today there are none. The government demanded that all universities be open to all, which has meant that all universities have had to become English medium. And no additional funding was forthcoming for the changes. The government policy amounts to a language “tax” imposed on the Afrikaans community for using Afrikaans.

“Only when all schools (and universities) are English will the clamor cease. Academics and educationists are beginning to speak openly of forming pressure groups to save Afrikaans schools, and of using litigation as one of their methods. 59% of Afrikaans parents have said they would support strong action if Afrikaans were no longer a medium of instruction at schools.”
