Abstract:A method of selectively controlling pyrophosphate-utilizing microorganisms comprises contacting said microorganisms with an organism controlling amount of certain organophosphonate compounds. Accordingly, a method of treating amoebiasis in a human or lower animal comprises administering to a human or lower animal in need of such treatment a safe and effective amount of such organophosphonate compound. Similarly, a method of selectively controlling Propionibacteria species in the manufacture of cheese comprises incorporating an organism controlling amount of an organophosphonate compound in the raw materials for said cheese.

2. A method according to claim 1 wherein the geminal diphosphonate compound is a member selected from the group consisting of ethane-1-hydroxy-1,1-diphosphonic acid, dichloromethane diphosphonic acid, methane hydroxy diphosphonic acid, nonane 1,1-diphosphonic acid, aminomethane diphosphonic acid, ethane-1-amino-1,1-diphosphonic acid, methane diphosphonic acid, nonane-1-hydroxy-1,1-diphosphonic acid, propane-3-amino-1,1-diphosphonic acid, the pharmaceutically acceptable salts of the above compounds, and mixtures thereof.
