PRACTICE 6 How to find the right disinfectant Themore insight customers give us into their everyday lives and tell us what requirements they have for a disinfectant, the easier it is to work with them to find a suitable product. The pathogen is crucial: is it a virus, a fungus or a bacterium? If you know the pathogen, you don‘t have to take the 'hammer‘ straight away and go for the product with the broadest spectrum of activity. And aspects such as exposure time, material compatibility or ease of use should also be taken into account. Basically, it is an interplay of infection and patient protection as well as occupational safety. Of course, the area of application also plays a role: What should be disinfected, the hands, skin, surfaces or instruments? Especially with instruments, it depends on how they have to be reprocessed. Can they be inserted? Do they have to be sterilised? We often receive questions about the virucidal spectrum of action. This is due to the irritating fact that viruses without an envelope are more difficult to inactivate by disinfectants than those with an envelope. These envelopes offer viruses many advantages. But when it comes to disinfection, they are a weak point. There is also often some confusion about sporicides. It is easy to think of fungal spores. In fact, sporicidal disinfectants refer exclusively to spore-forming bacteria. Fungicidal agents are recommended for fungal spores. Unfortunately, there is no ONE disinfectant for all cases. Many aspects can play a role in choosing one. We will help you find the product that best suits your needs. Efficacy & co. fungicidal against all fungi and fungal spores: Dermatophytes, moulds & yeasts yeasticidal against yeasts, e.g. Candida albicans virucidal against all viruses (enveloped and non-enveloped viruses!): e.g., SARS-CoV-2, HIV, polioviruses, adenoviruses, noroviruses and rotaviruses limited spectrum of virucidal activity against all enveloped viruses; plus: non-enveloped adeno- viruses, noroviruses and rotaviruses bactericidal against all bacteria, except mycobacteria sporicidal against bacteria spores (not fungal spores!) myco- bactericidal against all mycobacteria tuberculocidal against Mycobacterium tuberculosis You don’t have to take the ‘hammer’ straight away “ “ Laura Stirnberg, Expert Infection Prevention HARTMANN SCIENCE CENTER Classification according to pathogens: the spectrum of activity of disinfectants The extensively tested effectiveness of BODE/HARTMANN disinfectants also covers multi-resistant organisms (MRO). Resistance in such cases refers to antibiotics, not disinfectants. Virucidal against enveloped viruses against all enveloped viruses, e.g., SARS-CoV-2 Fungi Viruses Bacteria sporicidal against Clostridioides difficile
