Abstract

Methods and systems for monitoring and determining antimicrobial resistance and antimicrobial treatment using genomic subtype information. Various embodiments utilize molecular epidemiology and next-generation sequencing technologies (NGS) to monitor multi-drug resistant pathogens and provide early insight into emergent microbial threats.

First claim

What is claimed is:

1. A computer-implemented method for generating a subtype-specific display, the method comprising:
providing a computer processor configured to:
(a) receive information concerning the sensitivity of at least one isolate to at least one antimicrobial;
(b) receive information concerning the genomic subtype of the at least one isolate; and
(c) provide a graphical display of at least one number representative of the sensitivity of the at least one isolate to an antimicrobial, the isolates organized by genomic subtype.

2. The computer-implemented method of claim 1 wherein receiving information concerning the genomic subtype of the at least one isolate comprises:
(a) receiving data describing at least part of the genome of the at least one isolate;
(b) comparing the received genomic data from the sequencing operation against a reference database; and
(c) identifying a matching genomic subtype for the at least one isolate from the results of the comparison.

3. The computer-implemented method of claim 1 wherein receiving information concerning the sensitivity of the at least one isolate to at least one antimicrobial comprises receiving the results of an antimicrobial sensitivity test for the at least one isolate utilizing the at least one antimicrobial.

4. The computer-implemented method of claim 1 wherein providing a graphical display of the sensitivity of the at least one isolate to the at least one antimicrobial organized by genomic subtype comprises providing a graphical display in a matrix configuration with each row associated with one genomic subtype and each column associated with one antimicrobial.

5. The computer-implemented method of claim 1 wherein providing a graphical display of the sensitivity of the at least one isolate to the at least one antimicrobial organized by genomic subtype comprises providing a graphical display in a matrix configuration with each column associated with one genomic subtype and each row associated with one antimicrobial.

6. The computer-implemented method of claim 1 wherein providing a graphical display of the sensitivity of the at least one isolate to the at least one antimicrobial organized by genomic subtype comprises providing a graphical display of colored items in a matrix configuration.

7. The computer-implemented method of claim 1 wherein providing a graphical display of at least one number representative of the sensitivity of the at least one isolate to the antimicrobial comprises providing a graphical display of numbers in a column.

8. The computer-implemented method of claim 1 wherein each number is the prevalence of that isolate genomic subtype in a population in a particular timeframe and the sensitivity ratio for that isolate genomic subtype is displayed as a color or a shaded circle.

9. The computer-implemented method of claim 1 wherein each number is an average sensitivity for a plurality of isolates of a particular genomic subtype against a particular antimicrobial.

10. The computer-implemented method of claim 1 wherein each number is the sensitivity-to-resistance ratio for a genomic subtype against an antimicrobial.

11. A non-transitory machine-readable medium containing computer-executable instructions for performing a method for generating a subtype-specific display, the medium comprising:
(a) computer-executable instructions for receiving information concerning the sensitivity at least one isolate to at least one antimicrobial;
(b) computer-executable instructions for receiving information concerning the genomic subtype of the at least one isolate; and
(c) computer-executable instructions for providing a graphical display of at least one number representative of the sensitivity of the at least one isolate to an antimicrobial, the isolates organized by genomic subtype.

12. The non-transitory machine-readable medium of claim 11 wherein the computer-executable instructions for receiving information concerning the genomic subtype of the at least one isolate comprise:
(a) computer-executable instructions for receiving data describing at least part of the genome of the at least one isolate;
(b) computer-executable instructions for comparing the received genomic data from the sequencing operation against a reference database; and
(c) computer-executable instructions for identifying a matching genomic subtype for the at least one isolate from the results of the comparison.

13. The non-transitory machine-readable medium of claim 11 wherein the computer-executable instructions for receiving information concerning the sensitivity of the at least one isolate to at least one antimicrobial comprise computer-executable instructions for receiving the results of an antimicrobial sensitivity test for the at least one isolate utilizing the at least one antimicrobial.

14. The non-transitory machine-readable medium of claim 11 wherein the computer-executable instructions for providing a graphical display of at least one number representative of the sensitivity of the at least one isolate to the antimicrobial comprise computer-executable instructions for providing a graphical display in a matrix configuration with each row associated with one genomic subtype and each column associated with one antimicrobial.

15. The non-transitory machine-readable medium of claim 11 wherein the computer-executable instructions for providing a graphical display of at least one number representative of the sensitivity of the at least one isolate to the antimicrobial comprise computer-executable instructions for providing a graphical display in a matrix configuration with each column associated with one genomic subtype and each row associated with one antimicrobial.
