Abstract: The present invention relates to compositions suitable for use as topical pharmaceutical compositions for use in the treatment or prophylaxis of a superficial microbial species infection, and/or as anti-microbial cleansing compositions for use in the sanitary cleaning of animate or inanimate surfaces. The pharmaceutical compositions comprise a physiologically acceptable metal ion chelating agent and a pharmaceutically acceptable carrier therefor, in which composition said metal ion chelating agent has a metal ion chelating capacity for metal ions on which said microbial species is dependent for viability. The cleansing compositions comprise: a cleaning composition wherein is provided a metal ion chelating agent and in which composition said metal ion chelating agent has a metal ion chelating capacity for metal ions on which a microbial species is dependent for viability.
