Test Code YERSC Yersinia Culture, Feces


Ordering Guidance


This test is not intended to diagnose plague, which is caused by Yersinia pestis. Contact the laboratory for cases of suspected plague.



Additional Testing Requirements


If susceptibility testing is needed, also order ZMMLS / Antimicrobial Susceptibility, Aerobic Bacteria, Varies. If susceptibility testing is not needed (eg, due to lack of recovery of Yersinia species from feces), it will not be performed and the ZMMLS order will be canceled at time of report.

 

In some cases, local public health requirements may impact Mayo Clinic Laboratories clients, requiring, for example, submission of isolates to public health laboratories. Clients should familiarize themselves with local requirements and are responsible for submitting isolates to appropriate public health laboratories. Clients can obtain isolates of Yersinia species recovered from specimens submitted to Mayo Clinic Laboratories by calling 800-533-1710 as soon as possible after reporting (to ensure viability of the bacterium).



Shipping Instructions


Specimen must arrive within 96 hours of collection.



Necessary Information


Specimen source is required.



Specimen Required


Patient Preparation: Patient should not use barium or bismuth for 7 to 10 days before specimen collection.

Supplies: Culture and Sensitivity Stool Transport Vial (T058)

Container/Tube: Commercially available transport system specific for recovery of enteric pathogens from fecal specimens (15 mL of non-nutritive transport medium containing phenol red as a pH indicator, either Cary-Blair or Para-Pak C and S)

Specimen Volume: Representative portion of fecal specimen

Collection Instructions:

1. Collect fresh feces and submit 1 gram or 5 mL in container with transport medium.

2. Place feces in preservative within 2 hours of collection.

3. Place vial in a sealed plastic bag.


Useful For

Determining whether Yersinia species may be the cause of diarrhea

 

Reflexive testing for Yersinia species from nucleic acid amplification test-positive feces

 

This test is generally not useful for patients hospitalized more than 3 days because the yield from specimens from these patients is very low, as is the likelihood of identifying a pathogen that has not been detected previously.

Reflex Tests

Test ID Reporting Name Available Separately Always Performed
GID Bacteria Identification No, (Bill Only) No
ISAE Aerobe Ident by Sequencing No, (Bill Only) No
REFID Additional Identification Procedure No, (Bill Only) No
RMALD Ident by MALDI-TOF mass spec No, (Bill Only) No

Testing Algorithm

When this test is ordered, the reflex tests may be performed at an additional charge.
