Prof. dr. Sally Bloomfield: De last van infectieziekten is ieders verantwoordelijkheid - Een oproep voor een integrale strategie (EN)

Microbiome science now shows that interaction with our microbial world is essential to health.  The question is “how do we continue to protect ourselves against harmful microbes whilst at the same time sustaining exposure to essential microbes?” In 2018 group of experts in hygiene prepared a consensus paper on what needs to be done to address these apparently conflicting issues. The paper recognises that, in tackling these issues, a number of barriers need to be overcome:

  • the public are confused about hygiene - what it is and how it differs from cleanliness
  • the “hygiene” hypothesis misnomer has led to the misconception that we have become “too clean”.
  • The need to balance benefits of hygiene against factors such as environmental issues.
  • Concerns about antimicrobial resistance must be properly weighed against need for targeted use of disinfectants where necessary

To address these issues, IFH has developed targeted hygiene, a framework for maximising protection against infection whilst allowing maximum exposure to our microbial world. It also encourages focused use of resources (heat, water, mechanical action, detergents, disinfectants) in a manner which minimises environmental and other impacts. The paper makes calls to action to stakeholders in hygiene for a more integrated approach to hygiene and clearer messaging in order to restore public and understanding of hygiene and cleanliness.


Dr. Bernhard Meyer: Desinfectie en hygiëne om microbiële resistentie aan te pakken – een risicoanalyse (EN)

It is without any doubt that disinfection of surfaces, hands and medical instruments plays a crucial role in the prevention of healthcare acquired infections. Wherever antibiotics are used, be it prophylactically or as a therapy, mankind faces the development of antimicrobial resistance and antimicrobial drugs becoming inefficient. Therefore, the options of therapy of infections become less and, hence, the relevance of infection prevention increases. Disinfection plays a vital role in infecxtion prevention, but the question has been raised, if disinfectants can be a universal weapon against microbes spread via healthcare environments or if their use may even promote antimicrobial resistance. Based on a comparison of the risk of the latter happening and the risk of increased infection rates by limiting disinfectant use a proposal for the use of disinfectants in healthcare will be made.




Prof. dr. Jean-Yves Maillard: Biocidal products and usage: can they be implicated in emerging antibiotic resistance (EN)

There should be little doubts that microorganisms have a tremendous ability to adapt and survive antimicrobial challenges, to the point that, today, there is hardly any antibiotics left in our armoury to treat certain bacterial infections. With this in mind, the appropriate use of biocidal products can positively contribute to the prevention and reduction of pathogenic bacteria. In 2009, the Scientific Committee on Emerging and Newly Identified Health Risks published the “Assessment of the Antibiotic Resistance Effects of Biocides”, driven in part by the dramatic increase in the number of products containing (a) chemical biocide(s), and the detection of chemical biocides in the environment at concentrations conducive to phenotypic or genotypic changes in bacteria. Six years on, the number of products containing a chemical biocide continues to increase. In Europe, the Biocidal Product Regulation requires evidence that a biocidal product will not lead to bacterial resistance to that product or cross-resistance to unrelated antimicrobials. In the USA, the US Food and Drug Administration published a rule effectively banning a number of biocides, mainly cationic ones, from a number of consumers’ products. Although, the number of in vitro studies showing evidence of biocide-induced resistance and cross-resistance in bacteria is increasing, the question remains as to the implication of biocide usage on antibiotic resistance in situ.


Prof. dr. Markus Egert: Huishouden, hygiëne en het menselijk microbioom (EN)

Humans are colonised by about 10 trillions of microorganisms, affiliated with thousands of different species, and collectively referred to as the human microbiome. Although the details are far from being fully understood, it is undisputed that the human microbiome plays a significant role for human health and well-being. Structure (species composition) and function (metabolism) of the human microbiome are influenced by many intrinsic (host-specific) and extrinsic (environmental) factors, the latter including cleaning and hygiene measures and the composition of the household (built environment) microbiome. While many cleaning and household practices are indispensable to prevent infections, they are also suspected to negatively affect the human microbiome and promote diseases such as allergies and asthma. Clearly, balancing infection prevention and microbiome protection at home is a challenging task. More (large scale) investigations are needed addressing the (long-term) effects of cleaning and hygiene measure on the built environment microbiome on the one side and the human microbiome and human health on the other side. In view of the author, future studies should particularly address pre- and probiotic hygiene strategies to modulate the built environment microbiome in a way that is beneficial for humans.
