Panel:   Enteric Pathogen Diversity (GI)
AR Bank # 0403 Salmonella Stanley
Study ID: GI-03

Biosample Accession #: SAMN12648953

   

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).

Disclaimer:
For resistance determinant detection, 90% sequence identity and 60% sequence coverage was used. Biosample accession numbers have been provided so that users can analyze the data on their own if so desired. (M) = denotes mutational - gene and position (amino acid) are listed 23S - nucleotide 2075 For additional gene information please visit the Reference Gene Catalog - Pathogen Detection - NCBI (https://www.ncbi.nlm.nih.gov/pathogens/refgene), a non-redundant database of bacterial genes related to antimicrobial resistance, biocide and stress resistance, general efflux, virulence, or antigenicity.
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 18-24hrs.
