Merseyside SME develops new antimicrobial disinfectants

The Infection Innovation Consortium (iiCON) and its lead partner, LSTM, have supported Liverpool-based SME AmDel Medical with specialist product evaluation.

The Antimicrobial Chemotherapy and Resistance Group at LSTM worked with the company to test their MedibLU Universal Disinfection Formula (UDF) products and characterised four antimicrobial disinfectants, a new technology based on natural organic acids, as used in the food industry. They are designed to decontaminate healthcare environments but gentle enough for disinfection in the food, human, veterinary and farming sectors.

Previously fully EN tested by independent accredited test houses, the MedibLU products underwent further extensive specialist evaluation and laboratory testing utilising LSTM’s expertise, led by LSTM microbiologist Daire Cantillon.

Microbiologists tested the products against clinically challenging multi-drug resistant bacterial and fungal pathogens that are problematic for the NHS specifically and classified by the WHO as a top priority, such as MDR E. coli, colistin resistant E. coli, carbapenem resistant A. baumannii, MDR P. aeruginosa and C. auris.

The results of the tests, which were conducted over a number of defined time points, showed that all four MedibLU products tested performed extremely well and sterilised these problematic pathogens with 100% reduction of viable organisms (e.g. a 7 log kill for C auris, 9 log kill against Colistan resistant E.coli and an 8 log kill for the remaining pathogens). The results provide robust evidence that AmDel Medical’s MedibLU UDF range has potent efficacy against clinically relevant antimicrobial resistant strains.

Dr Adam Roberts, Reader in Antimicrobial Chemotherapy & Resistance and LSTM’s lead for Antimicrobial Resistance (AMR), said: “We’re delighted to have worked with AmDel to provide the necessary testing expertise to support and enhance product development.

“Our comprehensive test results showed that all four products performed extremely strongly when pitted against challenging multi-drug resistant pathogens and problematic micro-organisms – demonstrating potent efficacy and sterilisation capability.

“Supporting product innovation that tackles antimicrobial resistance and enables people to live healthier lives, is an important element of our work, and we’re pleased to have been able to leverage LSTM’s testing expertise to support AmDel in partnership with iiCON.”

James Lyon, AmDel Medical CEO, said: “As a local SME, we appreciate the opportunity of working with the world-renowned LSTM accessing their specialist support to verify our MedibLU biocide kill technology.  It is unique and very different from the conventional products but powerfully effective against the most clinically challenging microorganisms that NHS and WHO classify as problematic. Such valuable support has provided us further robust evidence and influential connections to help launch our MedibLU product range into to the disinfection markets of human and animal welfare.”

The activity was part funded by the European Regional Development Fund (ERDF) programme: Formulated Materials for Infectious Disease Prevention. This programme offers access to academic expertise to support innovation in Merseyside companies.
