The importance of hygiene in the past, present and future (Dr. John Hines)

Following the discovery of micro-organisms and the development of the "Germ Theory" of disease, hygiene played a vital role in disease prevention including healthcare, food preparation and storage and in many other aspects of everyday life. Indeed, before the discovery of antibiotics, disease prevention through proper hygiene was truly a matter of life and death. Today hygiene is no less important - it has been estimated that the simple act of regular handwashing with soap and water saves 2 million lives every year in the developing world - however a combination of our perceptions of the "cleanliness" and safety of the world around us, reliance and confidence in disease treatment and our emerging understanding of the complexity of the micro-world has lead to conflicted and often ambivalent views. In the future a decreasing reliance on antibiotics must re-focus our attention on disease prevention and on hygiene as essentials to health and wellbeing. A "targeted hygiene" approach must be developed and refined with the vital role of the human microbiome in mind.

10.30

The hygiene hypothesis in perspective (Prof. dr. Sally Bloomfield)

Evidence indicates the hygiene hypothesis is a misleading misnomer which is undermining attitudes to hygiene at a time when antibiotic resistance threatens effective treatment of infections. The hypothesis that children who have fewer infections are more likely to develop allergies is now largely discounted. The need is to develop new approaches to hygiene which maximise protection against infection whilst also sustaining exposure to the so-called "Old Friends" microbes which are important for health. Equally important, we need to change public and professional misconceptions about hygiene and cleanliness. In future we are going to have to view our microbial world very differently.

When cleaning makes things worse - the first microbiome analysis of used kitchen sponges (Prof. dr. Markus Egert)

The built environment (BE) of humans, and in particular kitchen environments and cleaning utensils, harbor a remarkable density and diversity of microorganisms, including pathogens. Our study stresses and visualizes the role of kitchen sponges as microbiological incubators in the BE, with the capability to collect and spread bacteria with a probable pathogenic potential. Follow-up studies will address the effect of different sponge sanitation methods in more detail as well as the transferability of our results to other cleaning utensils frequently used in kitchen environments.

Biocide susceptibility: towards realism in laboratory investigations (Prof. Dr. Andrew McBain)

Risk assessments of the potential for biocides to select for reduced antimicrobial susceptibility are frequently based on data generated through the laboratory exposure of bacteria growing in planktonic pure culture, to antimicrobial compounds in simple aqueous solution.
This presentation will describe a programme of research that aimed to assess these risks whilst taking into account variables including biofilm formation, growth in multi-species communities, potential effects on bacterial fitness of adaptation, and biocide formulation.

12.15

The risk of biocide resistance - the application view (Dr. Bernhard Meyer)

When reviewing the risk of antimicrobial resistance, it is of outmost importance to use correct definitions of biocide versus antibiotic resistance. Applying these definitions the risk of biocide resistance will be reviewed. Considering application conditions of biocides and history of biocide use the risk of spreading of any potential biocide resistance will be assessed.

Lunch break and visit exhibition hall

Parallel Afternoon Sessions (both in EN and NL)

During the afternoon sessions, participants can choose from one of four parallel sessions. In these sessions, specialist will elaborate on the topic of hygiene within a specific sector. Participants are invited to ask questions and take part in the discussion.
