Panel:   Multi-Mechanism (MULTI)
AR Bank # 1156 Pseudomonas aeruginosa
Study ID: MULTI-08

Biosample Accession #: SAMN34111342

mCIM Result: Positive    

Collection Year: 2018
Source: Urine
MLST: ST244(Pasteur)

MICs obtained by broth microdilution. Modal MIC is reported.

MIC results for each antimicrobial agent for an isolate may commonly be ± 1 log2 (doubling dilution) different than what is posted on the FDA & CDC AR Bank website because this is the normal technical variability of antimicrobial susceptibility testing (see J. H. Jorgensen. 1993. J Clin Microbiol. Vol 31[11]: 2841-2844).
Note: This AR Bank panel includes isolates that are pan-resistant, meaning they are susceptible to none of the antimicrobial agents tested which may include those commonly used to treat infections with these organisms. This represents an additional risk to staff working with these organisms and should be considered as part of the receiving facility risk assessment required by the Biosafety Compliance Agreement. The increased difficulty in treatment of any infection with those isolates should also be a consideration in deciding which protocols to use and precautions to take for working with these isolates.

1 Reflects MIC of first component
2 Cefepime to zidebactam ratio (1:1)
3 Screen for metallo-beta-lactamase production [Rasheed et al. Emerging Infectious Diseases. 2013. 19(6):870-878]
4 Clinical and PK/PD data demonstrate colistin has limited clinical efficacy, even if an intermediate result is obtained. Alternative agents are strongly preferred. Colistin should be used in combination with one or more active antimicrobial agents. Consultation with an infectious disease specialist is recommended.
Device manufacturers and users of FDA cleared devices shall consult the FDA’s Antibacterial Susceptibility Test Interpretive Criteria       website for breakpoints recognized or recommended by FDA, and for information regarding FDA exceptions or additions to the applicable, recognized consensus standard.

Disclaimer:
Antimicrobial Resistance (AR) gene prediction was performed using a combined and deduplicated AR database (ResGANNCBI) from ResFinder, ARG-ANNOT, and NCBI AMRFinder(primary Database) accessed on 2021-05-07. AR drug classes are assigned according to these databases. This analysis does not include mutations that may result in antimicrobial resistance, or resistance determinants added to newer versions of databases used, or other antimicrobial resistance gene databases. Additional AR genes other than those listed, may be present. For resistance determinant detection, 99-100% sequence identity and 100% sequence coverage from GAMMA (primary AR gene calling tool) and SRST2 was used. GAMMA uses amino acid sequence to assign gene alleles from assemblies; SRST2 uses nucleotide sequence to assign gene alleles from sequencing reads and is used to resolve AR gene calls located on the edges of assembly scaffolds detected by GAMMA. Biosample accession numbers have been provided so that users can analyze the raw sequencing data on their own, if so desired. *MLST Type (and scheme), as determined by Torsten Seemann's MLST program. For Enterobacterales the Pasteur MLST schemes are used except for E. coli for which both the Pasteur and Achtman schemes are reported. Similarly, for Acinetobacter baumannii complex, both Pasteur and Oxford MLST schemes are used and reported. SUB=novel MLST identified and "submitted". Dash (-) indicates no pubMLST scheme is available for that species. Truncated porins are defined as porin genes detected with ≥80% sequence identity and ≥80% sequence coverage and predicted to have an internal stop codon by c-SSTAR (https://github.com/chrisgulvik/c-SSTAR). ** Prescence of Efflux Pump may not be associated with resistance.
Propagation
MEDIUM
Medium: Trypticase Soy Agar with 5% Sheep Blood (BAP)

GROWTH CONDITIONS
Temperature: 35°C
Atmosphere: Aerobic

PROPAGATION PROCEDURE
Remove the sample vial to a container with dry ice or a freezer block. Keep vial on ice or block. (Do not let vial content thaw)

Open vial aseptically to avoid contamination.

Using a sterile loop, remove a small amount of frozen isolate from the top of the vial

Aseptically transfer the loop to BAP

Use streak plate method to isolate single colonies

Incubate inverted plate at 35°C ± 2°C for 18-24 hrs.
