Abstract
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.

Claims Analysis
Total Claims: 3
Claim 1
Independent Claim
155 words
A method for treating amoebiasis comprising administering to a human or lower animal in need of such treatment from about 0.1 to about 5 milligrams/kilogram body weight/day of a geminal diphosphonate compound having the formula ##STR4## wherein n is an integer from 1 to about 10, R 1 is selected from the group consisting of hydrogen, alkyl containing from 1 to about 20 carbon atoms, alkenyl containing from 2 to about 20 carbon atoms, phenyl, napthyl, phenylethenyl, benzyl, halogen, amino, dimethylamino, diethylamino, N-hydroxy-N-ethylamino, acetylamino, --CH 2 COOH, --CH 2 PO 3 H 2 , --CH(PO 3 H 2 )(OH) and --CH 2 CH(PO 3 H 2 ) 2 , and R 2 is selected from the group consisting of hydrogen, methyl, ethyl, propyl, butyl, amino, benzyl, halogen, hydroxyl, --CH 2 COOH, --CH 2 PO 3 H 2 , and --CH 2 CH 2 PO 3 H 2 , or a pharmaceutically-acceptable salts and mixtures thereof.
Claim 2
Independent Claim
155 words
A method for treating amoebiasis comprising administering to a human or lower animal in need of such treatment from about 0.1 to about 5 milligrams/kilogram body weight/day of a geminal diphosphonate compound having the formula ##STR4## wherein n is an integer from 1 to about 10, R 1 is selected from the group consisting of hydrogen, alkyl containing from 1 to about 20 carbon atoms, alkenyl containing from 2 to about 20 carbon atoms, phenyl, napthyl, phenylethenyl, benzyl, halogen, amino, dimethylamino, diethylamino, N-hydroxy-N-ethylamino, acetylamino, --CH 2 COOH, --CH 2 PO 3 H 2 , --CH(PO 3 H 2 )(OH) and --CH 2 CH(PO 3 H 2 ) 2 , and R 2 is selected from the group consisting of hydrogen, methyl, ethyl, propyl, butyl, amino, benzyl, halogen, hydroxyl, --CH 2 COOH, --CH 2 PO 3 H 2 , and --CH 2 CH 2 PO 3 H 2 , or a pharmaceutically-acceptable salts and mixtures thereof.
Claim 3
Dependent Claim
