Examining Antimicrobial Resistance (AMR) data in PATRIC

1. Finding AMR data in PATRIC

1.1. Using Global Search to find antibiotic information

  • 1.1.1. The Global Search box is located at the top right of every PATRIC page. Step 1
  • 1.1.2. Enter the name of an antibiotic of interest, and then click on the down arrow that follows All Data Types. Step 2
  • 1.1.3. This will open a drop-down box that allows you to filter on specific types of data. Click first on Antibiotic, and then on the search icon that you can see in the text box. Step 3
  • 1.1.4. This will open the search results page. You will see higher level categories in a box at the top of the page. Click on the number that follows the word Antibiotics. Step 4
  • 1.1.5. This will open the Antibiotics List View where you can drill down on information on specific antibiotics (described below). Step 5

1.2. Using Taxon landing pages to find antibiotic information

  • 1.2.1. From the Organisms tab, click on a genus of interest. Step 6
  • 1.2.2. This will open the Taxon View landing page, that summarizes all the data for that genus. A table that summarizes the number of genomes that have been identified as resistant, susceptible or intermediate is available on the top right. Step 7
  • 1.2.3. To find specific data on the AMR phenotypes, click on that tab at the top of the page. Step 8
  • 1.2.4. This will open a table that shows all the genomes across the genus that have been identified as being resistant, intermediate, or susceptible. Clicking on the filter icon that can be found at the top of the table will open a dynamic filter. Step 9
  • 1.2.5. The filter that has information on the phenotype, laboratory typing and testing methods that can be selected to narrow the number of genomes. Step 10
  • 1.2.6. The search can be narrowed by clicking on specific fields. Step 11
  • 1.2.7. Clicking of a genome of interest will show all possible downstream analysis steps or views will appear in the vertical green bar. Click on the Genome icon. Step 12
  • 1.2.8. This will open the Genome View landing page, where the AMR phenotypes are displayed on the to right. Step 13

1.3. Using the Data tab to find antibiotic information

  • 1.3.1. Information on AMR can be found by clicking on the Data tab, and then on Antibiotic Resistance under Data Types. Step 14

2. Exploring AMR data in PATRIC-Overview

2.1. PATRIC has a new landing page where information on individual antibiotics and the information on antimicrobial resistance for particular genomes and genes, and regions can be accessed. To find this data, click on the Data tab and then on Antibiotic Resistance, which you can see under Data Types. Step 15

2.2. This will open a page that defines antimicrobial resistance (AMR), and gives you access to different types of information on the antibiotics, the phenotypes, genes and regions associated with AMR. Step 16

2.3. Information about the antibiotics that are included in the resource. To see a total list of all the antibiotics available in PATRIC, click on “View all antibiotics” that is in the Antibiotics panel. Step 17

2.4. AMR phenotypes, which are liked at the level of individual genomes and are also summarized across taxon levels. You can see all genomes across PATRIC that have AMR phenotypic data by clicking on “View all AMR phenotype data” that is in the AMR phenotype panel. Step 18

2.5. PATRIC also provides information on genes that are linked to antibiotic resistance. Data is assembled from several sources, including the Antibiotics Resistance Database [1], the Comprehensive Antibiotics Resistance Database [2] and NCBI’s Bacterial Antimicrobial Resistance Reference Database (also called NDARO) [3]. The PATRIC curation team has also been working on AMR genes, and that data is in the resource as well. You can see all genes available in PATRIC that have some association with AMR resistance or susceptibility by clicking on “View all AMR genes” that is in the AMR genes panel. Step 19

2.6. PATRIC has also identified small genomic regions that are associated with antibiotic resistance. That effort, which examines AMR for a few taxa, has been published [4]. You can see of the small regions currently available in PATRIC that have some association with AMR resistance by clicking on “View all AMR regions” that is in the AMR Regions panel. Step 20
