Evolution Biotechnologies is working to expand biological control from its successful application within agriculture, bringing this to the control of medically important targets. Biological control is an environmentally friendly approach using natural agents. These are highly specific, reducing any side effects. They are applied in small doses and spread naturally, producing long-lasting and sustainable effects. Initial targets include: - The house dust mite, the major cause of asthma - The bedbug, a resurgent infestation - Pseudomonas aeruginosa, a bacterial infection that is highly resistant to existing antibiotics.
