Abstract
The present disclosure relates to novel lantibiotics, lantibiotic pharmaceutical compositions, isolated and recombinant lantibiotic-producing bacteria, bacterial pharmaceutical compositions, methods of producing novel lantibiotics from lantibiotic-producing bacteria, and methods of using such lantibiotics, lantibiotic pharmaceutical compositions, and bacterial pharmaceutical compositions to treat gram-positive bacteria infections, including vancomycin resistant enterococci infections, in patients, and to treat food and other objects to avoid gram-positive bacteria contamination.
Claims20
A method of treating a gram-positive bacteria colonization or infection, wherein the method comprises administering to a patient in need of such treatment, a therapeutically effective amount of a pharmaceutical composition comprising an isolated lantibiotic comprising a domain having the amino acid sequence of SEQ ID NO:
- 3 and a pharmaceutical acceptable carrier.
A method for treating a gram-positive bacteria colonization or infection, wherein the method comprises administering to a patient in need of such treatment, a bacterial pharmaceutical composition comprising:
- (a) lantibiotic-producing recombinant bacteria comprising an exogenous nucleic acid comprising the sequence of SEQ ID NO:
- 5 and operable to produce a lantibiotic having the sequence of SEQ ID NO:
- 3, wherein the lantibiotic-producing recombinant bacteria are bacteria that do not comprise an endogenous Lan A gene comprising the sequence of SEQ ID NO:
- 5;
- and
- (b) a pharmaceutically acceptable carrier.
A method for treating a gram-positive bacteria colonization or infection, wherein the method comprises administering to a patient in need of such treatment, a bacterial pharmaceutical composition comprising:
- (a) lantibiotic-producing Blautia producta bacteria comprising an expressible nucleic acid comprising the sequence of SEQ ID NO:
- 5 and operable to produce a lantibiotic having the sequence of SEQ ID NO:
- 3, wherein the lantibiotic-producing Blautia producta bacteria are Blautia producta bacteria that do not comprise an endogenous Lan A gene comprising the sequence of SEQ ID NO:
- 5;
- and
- (b) a pharmaceutically acceptable carrier.
