Together with many colleagues and a substantial part of the international health care research & providers community, I feel concerned about the increase of antibiotic resistant bacteria and fungi in our environment. The rapid development and spread of antibiotic resistant microorganisms is especially alarming in nursing homes and hospitals. We are observing how “super bugs” infect and kill hundreds of thousands every year. With the immune-compromised constituting particularly a high-risk group, we frequently stand helpless when even applying next generation antibiotics without success. When Better Air introduced their technologies to me about 3 years ago, I have found their concepts and problem-solving approach highly interesting. In the laboratory, the formation of a natural inhibition zone by some Bacillus strains against a pathogen indicates some form of antimicrobial activity that may be applied for controlling of detrimental microbes in the environment and/or within a specific ecosystem. By controlled application of such a carefully elected antimicrobial agent (bacterial strain) the need for use of chemicals and antibiotics may be reduced.
