Combatting anti-microbial resistance (AMR)

A3IS has proven to kill ESKAPE as well as critical and high priority WHO specified pathogens and established biofilms with no resistance observed.

A3IS is a viable alternative to increasingly ineffective antibiotics.

Core Developments – Multi Drug Resistant Pathogens

A3IS has proven to kill all ESKAPE as well as critical and high priority WHO specified pathogens. A3IS is highly effective at removing established biofilms and is a viable alternative to increasingly ineffective antibiotics

The discovery of antibiotics has long been regarded as one of the most significant medical achievements saving millions of lives and enabling the performance of difficult medical procedures. The emergence and spread of global antimicrobial resistance poses a serious risk to public health and the provision of effective healthcare.

A3IS has demonstrated exceptional anti-microbial efficacy against the most dangerous pathogenic organisms worldwide with no resistance observed.

A3IS has proven to kill ESKAPE as well as critical and high priority WHO specified pathogens as well as established biofilms and is a viable alternative to increasingly ineffective antibiotics.

National Institute of Allergy and Infectious Diseases

Further testing against the outstanding WHO pathogens will be carried out by the US Federal Government National Institute of Allergy and Infectious Diseases (NIAID).

A3IS and Antibiotic Area of Inhibition Test Examples

Figure 3 A3IS is highly effective against the critical priority pathogen carbapenem resistant P. aeruginosa. Note that the AOI achieved by meropenem was below the EUCAST specified sensitivity threshold of 255mm2. The tested pathogen can therefore be classed as carbapenem resistant.

A3IS and Antibiotic Area of Inhibition Test Examples

Figure 4 A3IS is highly effective against the high priority pathogen vancomycin and methicillin resistant S. aureus (MRSA).

Anti-Biofilm Testing

Bridge PTS (San Antonio, TX) carried out a study investigating A3IS’ efficacy against established biofilms. A complex biofilm containing S. aureus, P. aeruginosa and E. coli was cultured utilising a Modified Robbins Device (MRD). The test materials were added to the established biofilm and incubated (37°C) for 4 hours. Colony Forming Units (CFUs) were then established.

A3IS outperformed the Povidone Iodine Control and proved highly effective against the established biofilm.
